Hmmm...

  [Feb. 2007] When internal links go ... (external | bad)

When the Adobe Acrobat Menu Structure: Acrobat 7.0.8 to Acrobat 8 change summary (PDF: 236K), a very useful PDF for users upgrading to Acrobat 8.0, is viewed in Internet Explorer, the TOC links are not functional. Unfortunate... However, if you download the PDF to your computer, the links work. Strange... If you rename the PDF, the links go bad again. Stranger and stranger...

An examination of the links shows that even though these are internal links, the link action is "Go to a page in another document". As a result, when the PDF is stored on a web site and displayed through a web browser, these links are rendered non-functional because the although the links are internal, the PDF looks for another file (even though it has the same name). This also explains why if you rename the PDF saved on your computer the links go bad -- the links are still looking for a PDF with the old name.

It is very likely that in the case of this PDF (produced by Adobe's Knowledge Worker User Experience Group), this exotic linking method is yet another side-effect of FrameMaker's "Save as PDF" function.

Once again, the importance of systematic link checking of final PDFs is demonstrated. Simply opening the PDF in Acrobat/Reader and clicking the links will not reveal the problem in a case such as this.

And while you are about testing the PDF, make sure that the file's metadata is related to the content (especially if it will be placed in a web site and indexed by search engines). This particular PDF has a Title of TitlePage1.fm, and the Keywords are: Security feature user guide, digital signatures, security policies.

 

  [Jan. 2007] Question: What is common to the following PDFs (and several others) from the PTC web site?

Answer: They all have a PDF title of Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna, also seen in web searches [try it].

What is Lorem ipsum...? For a detailed explanation of the text itself, visit the Lorem Ipsum web site.

Where does it come from? It was used as a default title in the template used for these and other PDFs. For more information and examples, see related Hmmm... items: <This is a placeholder. Final title will be filled later.> (August 2005) and Keep it simple, but relevant! (December 2002).

Other PDFs in PTC.com offer the (unfortunately) all too common generic titles, such as Untitled, Layout1, Tutorial Template, No Slide Title, Special Report, Email Newsletter, RReevviieeww, CCoorree UUppddaattee, along with On the Word menu bar, click File > Properties and type the title of the book.

PS. And now you can guess how quick brown foxes are related to digital video, internet monitoring, ceramic fuel cells, theater reviews, legal agreements, and the Australian Treasury!

 

  [Dec. 2006] Ups and Downs

The paper was not placed incorrectly in the scanner; no hand-lettering or metal type were involved; and no, the underline was not drawn manually. Is this an exotic Acrobat display bug?

It is a FrameMaker document converted to a screen-optimized PDF (JSCollection.pdf file, included in the Acrobat 7 SDK and now also in the Acrobat 8 SDK); the likely cause is a slightly rotated text frame.

[FrameMaker Tip: hold down the Shift key when rotating a text frame by Alt-dragging, to constrain rotation to 45-degree angles.]

 

  [Nov. 2006] A Vision of the Future for Technical Communications?

"... With its flagship product, MadCap Flare, MadCap Software is leading the technical communications industry into the future..." (MadCap > About Us).

Now surely a company that sees itself as an industry leader and visionary has the highest of standards, and provides a shining example of how things should be done. Well, check out their documentation:

MadCap Flare 2.0, Getting Started Guide (PDF: 1.8MB, 130 pages): 55 bad links out of 325 links (of which some are duplicate), 0 links in the Index, 0 bookmarks, and the document title is "Title_Page".

If this is any indication of the investment they put into their product, potential clients should test it carefully before putting their hands into their pockets... And may I suggest that MadCap Software, as a company that sells software to technical communicators, add to their vision of the future new and better standards for the documentation accompanying technical communications products?

 

  [Oct. 2006] Code Fragments: What You See vs. What You Get

One of the immediate benefits of a programmer's guide provided as a PDF is that code fragments may be copied from the PDF file and pasted directly into text editors, reducing typing time/errors when studying or implementing the techniques discussed. But the text copied from Acrobat/Reader and pasted elsewhere is not necessarily the same as the source code when it comes to leading spaces or white space characters, line breaks or special characters.

One PDF that demonstrates various problems related to copying code is Adobe InDesign Programming Guide (PDF: 9.7MB). When copying the following code fragment (page 246)

and pasting it in Notepad, the result is:

The text extracted from Acrobat/Reader will not be identical to the text that you see in the PDF (or originally placed in the authoring application), as Acrobat has its own interpretation as to white space. If the code fragment is split between pages, the text of running headers/footers will be selected and copied as well.

Even though not common anymore in PDFs, problems related to font encodings may cause a situation where the pasted code fragment has no relationship whatsoever to the original text, such as the following code fragment (page 254)

resulting in:

(this applies to most code samples in this particular PDF).

The Adobe InDesign CS2 Scripting Guide (PDF: 2.6MB) goes to the extent of including the following note (page 3): "Because of the layout of this document and the nature of the copy and paste process, some long lines of code might include unwanted line breaks when you paste them into your script editor. In some cases, these line breaks will cause the script to fail. To fix the script, you must remove the unnecessary line breaks."
[This problem does not apply to other Adobe scripting guides/references, where security settings prevent copying text altogether -- such as Adobe Photoshop CS2 Scripting Guide (PDF: 0.7MB) or Adobe Photoshop CS2 JavaScript Scripting Guide (PDF: 3.3MB).]

An alternative solution to handling code fragments is to embed them as file annotations in the PDF, so that users (Acrobat/Reader 6 or higher) can open such embedded files by double-clicking or save them locally (see sample PDF).

 

  [July 2006] ePublishing: Whose Space?

When trying to locate the word "publishing" in FrameMaker 7.2: New Feature Highlights (PDF: 245K, 5 pages), five instances are reported.

But I found six other instances of "publishing" (in headings alone) which are not reported by Find/Search, due to the extra spaces present in Acrobat's recognition of that word. To locate these instances using Find/Search, you have to add spaces at different positions and search for strings such as:

  • pu b l i shing
  • pu b l i s h i n g
  • pub l i shing
  • publ i s h ing
  • publ i sh i n g

How come? Acrobat's text-analysis mechanism interprets a certain distance between letters as a space. When interpreting text that uses regular letter spacing (also known as spread or tracking), this mechanism generally produces reliable results; with loose text settings, the results may not be consistent and depend on the specific fonts and settings used. In such a case, extra "spaces" will be evident when text-related operations are used (for example: search or copy/paste), even though there are no spaces in the corresponding locations in the source document (regardless of the authoring program or distilling parameters). The looser the letter spacing, the higher the number of combinations which show an extra space will be.

Although this problem is not related to a specific font, it is more evident with san serif fonts (where there is slightly more natural space between letters, due to the lack of serifs).

A solution to this problem is available with tagged PDFs -- where text interpretation is not based on visual white space, but taken from another source embedded in the PDF file (and hence the much larger file size). Unfortunately, tagged PDFs introduce other types of problems...

 
 
 
 
 
 

 

  [May 2006] Why bother learning how to use a feature, if you can simply disable it?

From Redaction of Confidential Information in Electronic Documents, an Adobe technical note (PDF: 614K, 13 pages, March 2006): "Both Word and PDF documents can carry metadata information about the document, such as author, subject, keywords, and title. The author may be unaware of metadata generated by the application, and it may not be apparent unless the user knows where to look for it. ... The checkbox Convert Document Information controls the conversion of Microsoft Word metadata to PDF and is checked by default." This is followed by a recommendation to turn off this feature.

The importance of the Title field, and optionally other document information fields, was discussed in several Hmmm... items, together with numerous examples of how these fields may contain useless/ridiculous values ("This is a placeholder. Final title will be filled later") in PDFs. If the Convert Document Information option is turned off, as recommended by Adobe, then the Title (and other fields) will have to be entered manually every time the file is converted to PDF. It is true that sensitive/internal metadata should not be present in a PDF, but why recommend disabling a good feature instead of educating users as to how this is best handled as part of the authoring process in Microsoft Word? Adobe, as the parent of this useful feature, could be expected to work towards establishing standards for useful yet non-sensitive metadata, instead of throwing the baby out with the bath water.

Taking the logic behind the recommendation made in the technical note further:

  • Many PDFs have bad links, so why not simply turn off link generation? (The technical note itself -- a PDF authored with FrameMaker 7.2 -- has 18 bad links out of a total of 41, that's 44%!)

  • Graphics integration in PDFs often involves display/quality problems (and this document is no exception), so why not avoid having graphics altogether?


Furthermore, the technical note does not address a real issue: PDFs are commonly created from Microsoft Word by printing to the "Adobe PDF"/Distiller printer drivers directly (without PDFMaker), in which case the Title field shows the source file name/path and the Author field shows the log-in name -- which are potentially far more sensitive than Document Information fields set specifically by the document author (see examples). The Title is handled the same way, even when the "Add Document Information" field is turned off in the printer driver properties.

 

  [April 2006] Seeing double and triple (or even quadruple)

When using text shading (Microsoft Word) or artificially "bolded" fonts (Adobe FrameMaker), resulting PDFs have multiple instances of the same text, disrupting text-related functions such as search, copy/paste or "read out loud" (with some variations depending on the authoring tools, drivers, and Acrobat/Reader versions being used).

     

 

  [March 2006] e-book = any PDF?

What is an e-book? "Sometimes presented as Ebook or EBook, the term refers to a book that is available in electronic format. Usually eBooks are available in Adobe PDF or eBook Reader format, or in Microsoft's LIT format, but there are many other formats available. A good eBook uses the technology effectively, with tables of contents that link to the correct chapters and search capabilities. Links to Web sites and other files also can be included." (www.bookzonepro.com, Glossary)

The e-book (PDF) included with Microsoft Manual of Style for Technical Publications, 3rd edition could have been a great opportunity to demonstrate the added value of an interactive e-book, and the subject matter and technical character of the book certainly lends itself to interactivity. What a disappointment to discover that it is yet another sub-standard PDF promoted as an e-book. For starters, the table of contents has no links. Likewise, the index entries are not linked. Nor are the numerous cross-references throughout the book. In fact, this PDF has a total of ... one link (on page 318), which happens to be a bad link.

The PDF was authored with FrameMaker 7.0. As there are traces of FrameMaker-derived interactivity (e.g. destinations, bookmarks, article threads), it is highly probable that the links were removed after the PDF was created.

[Note: the PDF replaces a compiled HTML help (CHM) provided with the 2nd edition, which was fully-interactive and easy to use. As the PDF was created as a single PDF for the entire book, it does not utilize the potential benefits of Acrobat's search mechanism. Had this been a collection of separate PDFs, each with its own unique title (and possibly keywords), Acrobat Search could have yielded results similar to or better than those of the CHM search. With the "entire book = single PDF" approach, the reader is confined to clueless, serial jumps in a long document.]

 

  [Feb. 2006] Links: The Good, the Bad and the... Unintentional

The Open Service Event Manager User Guide (PDF: 1.9MB) has 50 bad links out of 908 links. Of the remaining 858 links, there are approximately 300 unintentional links. In addition, many of the cross-references are a combination of two links, one pointing to the heading number and the other to the heading text. When you consider these factors, the ratio of bad to good links is more likely in the range of one bad link out of every five links (most of the links in the Glossary are bad, for example).
[In FrameMaker-authored PDFs, a common reason for random bad links is having "Create Named Destinations for All Paragraphs" turned off in FrameMaker's PDF setup, Links tab.]

Unintentional links are often created in PDFs when cross-references are used in the source files for the purpose of retrieving text, for example a book title or release date. When such cross-references are placed in the header/footer and repeated on all pages, their presence becomes significant, and adds a burden to the file size without any benefit.

FrameMaker-specific: When using FrameMaker to author PDFs, it is highly recommended that you use variables and not cross-references for text retrieval. There are a number of reasons for this:

  • A large number of unintentional links is created when cross-references are placed on master pages, and these may also become bad links (depending on how the PDF is created)
  • Cross-references may cause formatting problems (for example, if you have italic/bold in the title text), because in cross-references, <$paratext> ignores all character properties present in the extracted paragraph text, with the exception of tag-based font family properties, superscript and subscript.
  • The links have an incorrect active area if there are variable-width items preceding the cross-reference (the active area on the current page corresponds to the required area on the previous or next page; zip with sample FM7 + PDF files).
    [With the FrameMaker-to-Acrobat TimeSavers add-on, it is possible to "disable" external cross-references pointing to a specific file/path (link is removed but text/formatting remains intact): Links/General screen, "Suppress x-refs when path or file name includes: ....".]

 

  [Dec. 2005] How to achieve quill-like effects without paying a graphic artist?

The Adobe FrameMaker 7.2 "Structure Application Developer's Guide" PDF has several diagrams which simulate FrameMaker's Structure View window, where elements are shown as bubbles (the one below is on page 168). The quill-like effects (display and print) are not related to drawing by hand, but to a new setting in Distiller 7. When "Convert smooth lines to curves" (Advanced tab) is turned on (and it is turned on by default in the "Standard" and "Smallest file size" options), FrameMaker rounded rectangles are warped (this has to do with the way FrameMaker outputs its graphic objects to PostScript, splitting basic shapes into multiple segments).

FM7.2 "Structure Application Developer's Guide", page 168

 

  [Nov. 2005] Warning! Empty Page!

When the View > Read Out Loud function in Acrobat/Reader 7 is activated in the Adobe FrameMaker 7.2 "User Guide Supplement" (52-page PDF provided as part of the product), Acrobat's computer voice says "Warning! Empty Page!" for about half of the pages (1, 2, 12, 22, 24, 28, 32-45, 47, 48, 52).

In the Adobe FrameMaker 7.2 "Structure Application Developer's Guide" (619-page PDF), the "Empty Page" warning is issued for all pages.
This PDF has a total of 109 bad links (in pages 30, 134-139, 202, 230, 593-600). Page 15 has 123 valid links even though it is really empty (link areas are displayed when Acrobat's Link tool is selected). The bad links are likely the result of having "Generate Named Destinations for All Paragraphs" turned off (FrameMaker); the superfluous links are likely the result of page replacement (Acrobat).


  [Sept. 2005] Practice what you preach?

"Making visually rich, personalized content reliably available anytime, anywhere, on any device" is the essence of Network Publishing. Yet Adobe's presentation of this concept, The Next Wave: Network Publishing (PDF: 801K), is a bitmap-based PDF. In such PDFs, text is not accessible (no search or copy), display/print quality is poor and typically the file size is larger than it should be.

text becomes a bitmap


Adobe, everywhere you look -- bitmapped Adobe, everywhere you look: The first and last page (identical) of the presentation consist of the Adobe logo and the "everywhere you look" phrase as text -- zoom in and the quality of text is not affected, and you can also locate the text by searching.

"Adobe, everywhere you look" is also present in all other pages, in a bitmap form, at the bottom-right corner. Because of the poor visual result, an opaque white rectangle with the Adobe logo (in a high-quality vector format) was placed on top of the "Adobe, everywhere you look" bitmap. When paging down, the "hidden" items show up briefly on screen (even though not visible in printed output). To see what's below the vector logo and the white rectangle, use Acrobat's TouchUp Object tool.

PS. When activating the View > Read Out Loud function (Acrobat/Reader 6 or higher) for the entire PDF, Acrobat has the following to say (in its synthesized voice): "You look trademark everywhere. BBC. BBC. BBC. BBC. BBC. BBC. BBC. BBC. BBC. BBC. BBC. BBC. BBC. BBC. You look trademark everywhere."

 

  [Aug. 2005] <This is a placeholder. Final title will be filled later.>
(or: Default PDF titles can be counter-productive!)

When PDFs are searched on the web, the PDF title (if present) is displayed in the search results. In the absence of a title value, content from the first paragraph is displayed (sample search, pointing to a sample PDF file).

PDF with no title

Generic titles assigned to PDFs by default are counter-productive, and far worse than not having any title -- as shown by countless Google search examples:

It is best to assign a unique, document-specific title for each PDF (and it is also possible to set the PDF so that it shows the title in the title bar when opened locally). If you don't plan to assign document-specific titles, having no title at all is much better than a default title.

 

  [April 2005] Lost the Index group title bookmarks (A, B, C...) in the user guides for Apple's Pages or Keynote 2?

They are alive and well in both books, but went astray. You can find them under the bookmark for the heading preceding the Index:

When PDFs are authored with FrameMaker (as is the case here), common reasons for incorrect bookmark order are multiple flows in the same document or disconnected pages.

  [Dec. 2004] White text is not always invisible

Coloring text in white to make it invisible is a common practice, but it is not recommended with PDFs used on-screen. In PDFs, the white text may be displayed (or even printed) in some circumstances. For instance, Acrobat/Reader supports different color schemes for background/text, through Edit > Preferences > Accessibility, even when the PDF is displayed through a web browser -- and when the background color is not white, white text shows up. In addition, "hidden" white text behaves like any other text: it can be selected inadvertently when copying, it is located by the Search function, and it will be spoken by Acrobat/Reader screen reader (View > Read Out Loud).

Examples below are from Adobe's PostScript Language Reference (PDF, 7.4MB) [same problems present in different versions of PDF Reference]:

  • Paragraph at the bottom of page 783

  • All chapters have the chapter number in small white type in front of the chapter title (same with appendixes -- as with Appendix F, page 795)




Notes:

  • "White is not invisible" also applies to graphic items, such as change bars or frames.
  • Small-size text which uses the same color as the background (supposedly "hidden"), may be greeked regardless of its color, displayed as gray lines. Zoom in to see what's in there, and it disappears (because it is not longer greeked). To control greeking in Acrobat/Reader: Edit > Preferences > Page Display, Use Greek Text Below __ .
  • When using FrameMaker as an authoring tool, specific colors can be suppressed from being displayed/printed through "Color Views" (e.g view #6 shows all colors, view #1 hides the 'NoPrint' color).

 

  [Oct. 2004] Zero interactivity

Multi-Edit Software's web site announces: "The New Multi-Edit v9.10 Manual is Online! ... Complete with all the new content ... Please note: This is an online version and the graphics have been compressed for easier downloading...".

But this PDF (289 pages, 2.9MB) has zero links, zero bookmarks. And many potential users are likely to have zero tolerance for such an online manual.


  [Aug. 2004] How to link and link and link and link ... from a single TOC entry?

Arbortext's Technical Support Guide (26-page PDF), "created and published using Arbortext Software", has a Contents page with 32 entries which use 226 links -- that's an average of 7 links per entry. The links point to the corresponding pages (and not to the specific location of the heading on a page, which is less convenient if the heading happens to be placed at the bottom part of the page), but otherwise they are all valid.

link rectangles are displayed when Acrobat's Link tool is selected

The PDF has bookmarks, but does not specify these to be displayed initially. Bookmarks for chapters are present as numbers only, with no text; bookmarks for the headings include the paragraph number together with text (in the case of 3- and 4-level headings, numbering often causes heading text not to be displayed in full in the bookmark pane).

  [June 2004] Help! Acrobat article threads!

The default setting in many FrameMaker templates and documents is to create Acrobat articles from text flows. Even when implemented properly, the presence of articles is often problematic, since many PDF users are not familiar with this feature and do not know how to use it efficiently. They may try to click a link, but activate the article instead; they are not taken to the expected location, and the view/zoom changes as a result of the article activation (hiding buttons or navigational items, if present).

A demonstration of another aspect is provided by the PDF file of FrameMaker 7.1 Reviewer's Guide. When providing an article thread in a multi-column layout, it is essential that the article's beads match individual columns, and not the page. Having three columns treated as a single bead is counter-productive. As the article is activated, the three columns are displayed. Additional clicks scroll the three columns as one unit and then continue to display the next three columns on the following page, rather than the top of the next column in the current page.

Note: same applies to the "User Guide Supplement" PDF provided with FM7.2

(cursor indicates presence of an article thread)

  [April 2004] On [line] page.

These and several other cross-references in FM7.0/FM7.1 online help point to page numbers, which are of course irrelevant in an online help format. Moreover, the page numbers do not even correlate with the relevant information in the FM7 printed user guide.

Thus, according to the version information file, the FM7.2 help was compiled on March 14, 2002 -- i.e. three and a half years before the actual product was shipped.]

  [Nov. 2003] !#"%$'&() ???

When searching for PDFs on the web, you may be surprised to see results displayed with titles that have random-looking letters, such as oooooo, aaaaa, ggggg, rrrrr, or even !#"%$.

A common reason for these strange-looking titles is missing DocInfo/metadata fields. In their absence, web indexing mechanisms resort to displaying the title using what seems to be the beginning of the content -- which may have duplicate text strings (sometimes used by applications/drivers to create a "bolded" version of the text), text-based shadow effects, decorative dingbats, special symbols or form field elements. Some font-related problems may also cause the underlying text to be very different from the text displayed in the PDF page.


  [Oct. 2003] Cannot locate Microsoft in Adobe's OpenType User Guide (PDF: 999K, produced with InDesign 2) even though you see at least one instance on screen?

Advanced typographical features available with OpenType fonts (including ligatures, small caps, oldstyle figures) help produce superb type (print and display), but may cause problems when the PDF is used online. Acrobat does not recognize some of the resulting characters (even when it's a Tagged PDF), so that although you see the words on the screen, the internal text representation is garbled -- disrupting the Find/Search and Copy/Paste functions. In the paragraph shown above (page 2), you won't be able to find the words file, SFNT, This or suffix either.

  [June 2003] No time for niceties?

Acrobat 6 Core API Reference was made available (PDF: 12.1 MB) late May. Still labeled as "draft", it does not have even a draft table of contents for its 3357 pages.
Update (11/03): The final version, dated November 25, 2003, does not have a table of contents either.

Note: The Acrobat 5 Core API Reference PDF was briefly reviewed, among other PDF files included in the Acrobat SDK documentation set, in PDF Best Practices #3: Links Can Guide the Way (12/2001): "...You would expect that CoreAPIReference.pdf, being a 2750 page PDF, would have a detailed and fully-linked table of contents, making it easier to locate items or navigate in a document of this scope. The Table of Contents is slightly longer than one page (!) – it has 19 items in total. And to make it even more absurd, these items are not even linked..."

 

  [May 2003] Link automation is great, but it's even better when a human inspects its results

Sun MicroSystems' Product Documentation site has quite a few PDFs, authored with FrameMaker. The link area in tables of contents is inconsistent, sometimes containing only one word or one character, and does not include the page number. Below are sample link areas as displayed when Acrobat's Link tool is selected (Acrobat Reader users need to "hunt" for links by moving the Hand tool and watch for the change of cursor).

  [March 2003] The Big A (for Apple)

The QuickTime 6 API Reference -- which "documents every function, struct, data type, and constant in QuickTime" -- is a whopping 36M PDF file! With very little effort (and without even having access to the source files), the file size can be reduced to a 14M PDF without any loss of functionality.

Over 50% of the 36M PDF is related to superfluous named destinations. But this reference-oriented PDF isn't that generous with bookmarks. There are only 25 bookmarks for 2200 pages of alphabetic function listing. Want to locate information on the MusicSetPartInstrumentNumberInterruptSafe function? Well... click the M bookmark, which takes you to page 832. The item you need is only 248 pages away (page 1080) -- use the page down key or scroll to get there. Sure, you can also use Acrobat's slow Find function, if you are patient enough and can type the function name without any typos. Considering using the Table of Contents to quickly get to the item you need? Don't bother, as it is not any more detailed than the bookmarks.

     


  [Feb. 2003] Adobe Acrobat 5.0 at Work?

Adobe Acrobat 5.0 at Work: Engineering How To Guide (3MB / 76 pages) discusses how to "create reliable Adobe PDF files for efficient exchange of engineering documents" and more. The introduction states: "Acrobat converts files to Adobe Portable Document Format (PDF), a universal file format that preserves all the fonts, formatting, graphics, and color of source documents, regardless of the application and platform used to create them." But not regardless of appropriate ingredients and parameters, as this PDF file demonstrates. When fonts are not embedded, Acrobat resorts to font substitution with variable results. When excessive downsampling is used, images and bitmapped text may lack significant details.

  [Dec. 2002] Keep it simple, but relevant!

The documentation download page for Enfocus Instant PDF has links to 16 different PDFs. The document developers certainly made their life simple - they used the same PDF document title ("Enfocus End User Documentation") for all PDFs, regardless of its relevance to the content or to the document language. This generic title is also used in PDFs for other Enfocus products.

The PDF DocInfo Title field should be highly specific, as it is

  • optionally displayed in the title bar, where it serves the user much more than a file name
  • listed in Acrobat's Search Results box (in fact, to optimize Acrobat's Search performance, a longer manual is best split to different chapters, each with its own unique Title, Keywords or Subject fields)
  • used by many web search engines as the document's title (see below)

 

  [Nov. 2002] Q: What weighs more: English, French, Spanish or Portuguese?  A: French

Qualcomm's documentation download center contains PDFs of four identical versions of the GSP-2800/2900 User Guide in these languages. Three weigh approximately 1.2MB, one weighs 4MB.

French may be tough for some people to learn, but having examined the PDFs using Acrobat's Tools > PDF Consultant > Audit Space Usage function, it seems to me that in this case it is the graphics to blame, not the language. The French version was distilled using drastically-different job options. No one seems to have questioned the significant file size difference, not even the web master who diligently indicated the file size for download purposes.

Q: Which markets require document usability?  A: Apparently Spanish-speaking countries.

The Spanish version of the above document is the only PDF with basic interactivity -- bookmarks, linked table of contents and index (but unfortunately 7 links in the 1-page index are invalid).

Moral: Always thoroughly test PDFs before distribution!

 

  [Sept. 2002] Scanned PDFs

Scanned PDFs are associated with lower display/print quality, excessive file sizes, non-functional Find/Search functions (unless an OCR layer is added, and even then, searchability may be limited).

Why would someone scan a high-quality, text-based PDF into a bitmap-based PDF? In the case of the freely-available PDF of Acrobat Shortcuts, it seems that the reason was the unethical deletion of the MicroType logo and line (including the URL, where an updated version may be found).

This is MicroType's Acrobat Shortcuts PDF, discovered at the U.S. Department of the Interior's Minerals Management Service web site:

This is the original version (free and updated) of the Acrobat Shortcuts PDF (116K), still available at the Resources section:

 

  [August 2002] Adobe FrameMaker 7.0 Solutions Guide

Adobe FrameMaker 7.0 Solutions Guide (PDF: 7.65MB / 123 pages), page 9-3: "FrameMaker... maximum PDF publishing integration... automatic bookmark generation, automatic production of hyperlinked tables of contents", yet these were created manually in that PDF (authored with FM7.0).

When selecting the Link tool while in the TOC pages, one sees uneven/overlapping links (not created automatically by FrameMaker):

The random extra spaces in some bookmarks indicate manual creation (New Bookmark when text is selected with Text Selection tool). The extra spaces are also an indication of text-related problems in the corresponding pages, and will affect Find/Search or copy/paste operations.

[September 2000] Is This a Useful PDF Reference Point? Adobe’s own PDFs offer no benchmark for users.
