	Originally Posted by: Guest I decided to give it a quick go and test it with a PDF containing mostly JBIG2 images (grayscale). A lot of HP MFPs seem to prefer this image format when scanning documents. Well, the extracted images are just completely black, so something's not working as it should. I used the sample code in the SDK user manual to extract and save the images, and the latest Nuget package to test it. fixed! https://forum.patagames....on-Jun-18--2019#post1661

	I'm afraid the document I'm testing on contains sensitive information, so I can't share it. I'll see if I can find a similar document scanned using the same settings which I can send to you. The image XObject for one such image has these keys, if that helps you: Code: `/Type /XObject /Subtype /Image /BitsPerComponent 1 /Length 26334 /Width 3508 /Height 2480 /ColorSpace /DeviceGray /Filter /JBIG2Decode` (Essentially, the entire PDF page is just an image).

	Could you please provide the document with such images. I would like to examine it on my side. Thanks.

	As I know all that decoders are supported. So you can easily get access to converted System.Drawing.Image through PdfImage.Bitmap.Image property No external decoders are required.

	I'm trying to find some information which raster image formats are supported by Pdfium, but I can't find anything specific on your website. Are DCTDecode, JBIG2Decode, JPXDecode and FlateDecode all supported? E.g, if I process an image XObject that's using the JBIG2Decode filter, can I get a converted System.Drawing.Image or System.Drawing.Bitmap from this that I can process/save/whatever or is a separate JBIG2 decoder required?
