Fail with PDF Mask #3

Open maxpowel opened 4 months ago

maxpowel commented 4 months ago

I am getting this error while processing the attached PDF:

thread 'main' panicked at /media/storage/vortex/src/writer/mod.rs:36:13:
source slice length (23040) does not match destination slice length (69120)

In the file https://opensource.adobe.com/dc-acrobat-sdk-docs/pdfstandards/pdfreference1.7old.pdf page 222 there is a little description about it.

Looks that the image contains another image wich is the mask applied to the first one. The PDF contains two images that should look like this 0 1

It is weird that the content size does not match the width X height but all PDF viewers I tested, open and show correctly the images so I guess that the PDF is correct.

Hi sorry I couldn't respond in the past few days. I'll take a look into this
