[Plugin: POST2PDF Converter] Png images 100% CPU

  • I have enjoyed using the excellent post2pdf-converter plugin. And I also use the tcpdf library which has been very helpful and very frustrating from time to time. On WP 3.34, I have observed that posts with PNG images when saving as a pdf using this plugin causes near 100% CPU until the process times out. This also happed on the previous versions of WP 3.3x.

    I disabled all other plugins but still I get always the runaway CPU. The tcpdf program, while a wonderful facility has no error return values and I think that cause a lot of us problems tatcking down errors.

    If anyone has a solution for this PNG specific problem, I will be happy, happy!

    The Jul 3, 2012 TCPDF Version 5.9.172 fixes the 100% CPU problem for pages that have Png images in them.

    I retrieved the tcpdf version from https://freecode.com/projects/tcpdf
    and replaced the “post2pdf-converter” folder “tcpdf” with this new one.

    The tcpdf/cache folder needs to be writable by the web server.
