I have a PDF that contains images. When I read it your library correctly finds all images. However when I try to read the image data I run into problems.
1) I have a simple drawing as an image. Compression attribute gives 11. In your documentatio there is no value 11. The largest value is 10 (acCCTTTFax). What does this 11 mean? Anyway I get the image data correctly from BitmapData attribute.
2) Another image is originally a JPEG photo and Compression attribute gives 7 (acJpegMedium). This is OK. However the BitmapData gives empty byte array. Is there some other attribute that contains JPEG compressed data?
Best regards,
Johannes
