Thanks, Leonard! Before I submitted my question to PDF-dev, I'd experimented with Quite Revealing and Quite A Box Of Tricks, and it appeared that I wasn't getting the info that I needed. After you suggested Quite A Box Of Tricks again this morning, I had another go with Quite A Box Of Tricks and realized that I had not been using it correctly when I tried it the first time. Aandi - the image information that I got from QBox is "JPEG, 3.0 med/lo/4.05 max" If LZW had something to do with it, the string "LZW" would have been included in the QBox "Image information" dialog box, right? In case anyone is curious about why I need this information, here is the background: We're working with a customer that has used variable-data-printing software (DL-100 from Datalogics) to create customized documents with a layout that's quite unusual. It looks great on screen, but we have not yet found a RIP that will process it - every RIP we've tried has slowed to a crawl and refused to spit out even one page. I didn't build the file, but I'm told that transparency is used in it, and it's my understanding that there's a lot of RIP overhead when a RIP has to deal with transparency. Also, just recently, I was talking with someone that said that he's observed that many RIPs slow to a crawl when processing LZW-compressed images in PDF files - and this is what prompted my "Identifying LZW-compressed images in PDF" post. The problematic file is in http://www.CitationSoftware.com/Demos/Midland/output_test_4up.zip. If anybody has ideas or comments about this issue, I'd appreciate hearing them.
