I have imported a bunch of images from a PDF file, which, besides the problems listed on the other question I posted today (related to the apparent absence of a ASCIIHexDecode decoder), originated images that, visually inspected, seemed identical to the original PDF content.

After performing some image processing on them, I wanted to place them back into a PDF file.

The problem is that there seems to be no options for the export of raster images into a PDF, like, for instance, the "filter" to be used (the encoding): DCTDecode, LZWDecode, JPXDecode, ASCIIHexDecode, etc. and their corresponding options.

Unfortunately, the default Export result is very far from my needs. Am I missing something?

Also, it is not clear to me how to define a PDF page of a specific size. Am I supposed to compose a Graphics with the raster inside? Are there examples of this available?

Thank you,
