Daniel Kuhlmann Posted March 27, 2020 Share Posted March 27, 2020 When I export a 16bit image that has neither been downsampled or cropped by Publisher, the PDF correctly includes a 16bit image. However, if the image has been downsampled or cropped by Publisher, the PDF shows an 8bit image. Although there are not many use cases for 16bit images in PDFs, I assume that it will lead to possible confusion and errors if 16bit and 8bit images get unintentionally mixed in the same PDF, just depending on whether they were cropped in Publisher or not. Many thanks, Daniel Link to comment Share on other sites More sharing options...

Please clarify how you are downsampling. Is that via the More options during Export? Or some other way? Also, there are several ways one might crop an image in Publisher, including using the Crop Tool in the Publisher Persona, or a Picture Frame, or clip-nesting with a rectangle. Which method did you use? Can you provide a sample .afpub file, and the Export settings you used?

Daniel Kuhlmann Posted March 27, 2020 Author Share Posted March 27, 2020 Thanks for your quick reply, Walt. I used a Picture Frame. For export, I started with the standard PDF (for print) export setting and deactivated "Allow JPEG compression" as JPEGs can only be 8bit anyway. A sample .afpub file and linked 16bit image are attached. Best, Daniel Pub_16bit.tif 16bit export.afpub Link to comment Share on other sites More sharing options...
