We recently generated an entire users manual for one of our products as a Confluence (v4.1) space. It looks great - until we do a PDF export. Many of the screenshot images in the export appear to have been resampled. Some of the text in the images is now unreadable. I know we can work around some of this by carefully choosing the size of our original images, narrowing the scope of the image, etc. But what I am wondering is this:
Are any settings in Confluence or in the PDF stylesheet (or anywhere else, for that matter) that we can use to modify how the images are being resized/resampled during conversion to PDF?
We had a lengthy discussion about image quality in PDF export at https://answers.atlassian.com/questions/93381/column-width-and-pdf-export#comment-148155
It developed quite a bit so it can be confusing. Bottomline is you need very big images on the wiki page to get good images in the PDF. Using thumbnails to make the images smaller often causes even worse results in the PDF. But there is some kind of a workaround...
