I've been looking through the documentation and examples of
PDFSharp-0.9.653,and the ExportImages sample says:"JPEG has native support in PDF and exporting an image is just writing the stream to a file."
so it's very easy to extract the jpeg from a pdf.i just think a question:the jpeg in pdf is same as itself as a image?and other format image file is different,so the other image except jpeg can't be written the stream to a file(such as tiff,gif,png etc.).the reason is the image file(tiff.gif png) is compressed in pdf,so it is difficult to extract it from the pdf.How can i do it,how can we extract the other image format from a pdf with pdfsharp? i know is possible,but i don't know how to do it?

Thanks,
