While recently trying to upload a process diagram (a PDF, generated by a digital whiteboarding tool) to a customer's repository I ran into the error "A generic error occurred in GDI+.".

Printing this to a smaller (ARCH D, 24"x36") paper size using Adobe seems to have resolved this so I'm guessing this has to do with the page size.

If it's not possible to support the generation of pages/OCR text over a certain size limit (which removing said limit would be the ideal solution), then it would be nice if there was an option to automatically downsize PDFs to an uploadable/proccessable size (ideally with a prompt, so the uploader is aware of the processing) instead of giving an generic error which then has to be researched and remedied with a third-party tool (Adobe Acrobat/other print-to-PDF driver, which not all users might have installed).
