Blank PDF when drawing lots of large images

1. offizieller Beitrag

    Hi,

    We use wPDF 3 and have the latest version.

    When our application exports a PDF file containing a lot of high resolution images to a single PDF page, the PDF file is blank but the correct page size. We can create large PDF pages with a small number of images no problem. Sometimes, if there are a lot of them, some of the images will be missing from the PDF file.

    No errors or exceptions occur during the PDF export.

    Is this a memory issue in wPDF or just lack of Windows resources?

    Hi,

    Please use FastMem to maske sure there is no memory leak.

    Inside wPDF there is no known leak, but it is possible that the image get lost when passed to the DLL.

    It is also possible to pass JPEG directly to the PDF engine. In this case they will not be compressed but taken as they are. That can help if your many images are JPEGs.
