ExtractImages() exception

[Massimo Cicognani]

Hi,

in my application I read a PDF and extract its images to process them later.

I discovered that some pdfs are corrupted due to problems during the transfer, and so far there are no problems as I closed the entire code block inside a try catch to intercept them.

I encountered the problem in a damaged PDF which opens correctly but when I call the ExtractImages() function on a page it throws an exception (screenshot attached)

Since it is an automatic procedure, I cannot know a priori whether the PDF is damaged or not, I just wanted to report this problem to find out if it is something normal or if it is something that can be fixed somehow.

Hope this can help
