Pdfium viewer dont see some pdf content. You cant see some images in doc.
If you check the same doc with Adobe Reader all fine.
Check 59, 60, 61 pages in this doc in your viewer and in Adobe. You will see bug :

I hope some one can fix this problem!

We can take a look, but the PDF may be bad. Microsoft Edge and Apple's Preview.app cannot render page 60 correctly either. Using pdf2ps from Ghostscript, the PostScript output is also incorrect.

Document not bad. I can send many docs like this and you will see that Adobe read them correct and Pdfium not. Do you need more samples ?

Without more analysis, I cannot say for sure whether the sample PDF is good or bad, which is why I said "may be". In any case, the fact remains that multiple PDF viewers cannot render the document correctly.

It looks like "doPDF" is the software that produced the sample PDF. Have you asked them about this?

We probably do not need more samples, especially if they are all generated by the same software.

The problem is : Adobe work correct with this file and Pdfium not. Maybe its about content detection in Pdfium ?
Btw - soraxsoft viewer (Sorax Reader ) see content correct too. So i hope you can fix this in Foxit and Pdfium.

I can provide you more samples file and you can find out why some content dont recognize.
Check pages in this doc : 247 253 500 ( Abobe and Sorax work correct)

The original link is dead. I took a look at page 500 in the comment 5 link, and it looks like the missing image object has a dictionary that looks like:

<<
/Mask [1 1]
/Subtype /Image
/Type /XObject
/Width ...
/Height ...
/Length ...
/BitsPerComponent 1
/ColorSpace [...]
>>

If I remove the /Mask, then the image renders correctly.
