Wrong image rotation on some files with `add-image` and `sign` tools

[paspo]

In some pdf files, when I put an image with the add-image or the sign tool, I obtain a PDF with the desired image but in a different position, with wrong dimensions and wrong rotation (always 90° ccw).

I can resolve this issue by:

• opening the original file with LibreOffice Draw and exporting it in PDF without modifications
• using the pdf repair tool on the original file

There's clearly something wrong with the original files, but I don't have enough data ATM. I can safely say that this has nothing to do with PDF version (some files are 1.3, others are 1.7 ...) I can also exclude the image file format: the problem arises with jpegs, pngs...

Even if I understand that the problem is in the "somewhat broken" input files, I think that there's the possibility that solving this issue can lead to a more robust processing.

I can provide some example files to any contributor asking for it, but not publicly; DM if interested.

Thanks.

Can you send me the example file? I am the main contributor and admin of the discord if you want to PM me it there

For anyone to try, here's a sample file. It's a PDF generated by a MFP. scan258275.pdf

This issue is still present in 0.10.3

The problem is that the orientation of the PDF in your file is 270°, which is where the incorrect ratio calculation comes from and the incorrect aurization of the image.
