I searched the forums for this, but did not find a thread that directly addressed this issue. When I export pdfs from InDesign CC(2014), and use the setting "crop image data to frames" checked on, but do not otherwise downsample or compress the images, the images are NOT cropped to the frame edges. I found this out with the "edit in Photoshop" from the tools in Acrobat Pro (XI). I have not tested with other settings for downsampling, as I don't want to downsample these images. These particular images are scans from a copier/printer - bitmap images. I understand that it does not work on vector data, but this is not vector.
