iPad and images in PDF's

Not. I've tried three PDF readers, PDFMate, Stanza and your recommendation Good Reader along with Safari and none render many of the images, maps and graphs in the document, which you can find at:

http://www.wsrphoto.com/web-files/CarbonRiverESA.pdf (warning it's 346 pages)

I've tried other scientific publications and almost all don't render some to many of the graphic formats in the document. And these PDF's were created from a variety of publication and word processing applications (eg. Word, FrameMaker, etc.). I'd like to know if you or anyone can see the images, starting with the one on the cover.

The problem isn't the text in the document, those are fine in these readers, it's the images, maps and graphs that's the problem and it's something with iPad. Right now I'm negotiating with one agency to get a copy of the original to examine the images in the document and look at converting them to iPad compatible ones.

Ok, some clues. Working with the PDF in Acrobat I discovered many the images, maps and graphs in the document are composited images, meaning composed of 8-10 vertical or horizontal slices, and while it works and looks fine in the PDF, apparently iPad has issues with it. Only those images which are whole, and not composite or combined (meaning more than one image as one large image), display in the PDF readers or in Safari. This is a problem with some of the government publications I tested, but not all as some displayed complete.

As a futher test I loaded a 300+ MB publication, see "The Whole Book" at:

http://www.wsrphoto.com/mtdnrbook.html

and while it wouldn't load in Stanza, it did load in GoodReader and everything displays fine. So it's in the images either pre-import of the PDF or in the production process of the final PDF or in the PDF capabilities in the iPad.

Except after reading the review I didn't find any direct information stating that iPad's don't display images in jpeg2000, although I found references elsewhere, except the solutions don't alway work (resaving a PDF in Acrobat), converting jpeg2000 to jpeg. The problem isn't the image format but the image slicing. The iPad can't recognize a set of sliced images as one to composite them into one for display.

Sure, it's at:

or at the bottom of the Web page at

When you extract the images, maps and graphs in Acrobat, many export as 8-10 horizontal or vertical (long axis) images. Acrobat on the Mac has no problems rendering it right, but on the iPad it's blank areas. I've tested other PDF with the same problem.

On the working side with the iPad I've loaded entire geology guide at

see link to the "Whole Book" in list of chapters. Every image, map and graph display fine (and make a cool carry along book for road trips).

Thanks, I will try that. I used Acrobat save as and export of which neither worked.

Thanks that worked. Preview must composite the sliced images, maps and graphs into a single version which PDF readers on the iPad can display. I've only tested three PDF readers, and GoodReader has the highest file size allowed.
