WPViewPDF-Demo and some Problems

1. offizieller Beitrag

    Hi,

    Please see this file.

    This is a small PDF File in german containing some bitmaps. I've tried to display and print it using the latest wpViewPDF Demo.

    Some problems here:

    * one bitmap is not displayed at all, one bitmap is displayed in a wrong color scheme
    * german umlauts are not displayed, they are only displayed if I disable the "advanced text rendering for embedded fonts"
    * if I use the printit.exe utility to print this pdf, german umlauts are replaced by a strange symbol character, same bitmap issues...

    So I am a little bit puzzled, can you help me? I'd love to use it to implement an embedded pdf viewer / printer in a VCL-application...

    Thanks,

    Daniel

    Hi,

    * one bitmap is not displayed at all, one bitmap is displayed in a wrong color scheme

    RGB, grayscale and CMYK JPEG are supported.

    * german umlauts are not displayed, they are only displayed if I disable the "advanced text rendering for embedded fonts"

    I have to check if an update to the FreeType module helps here. With compressed fonts it does not seem to find the gylphs.

    * if I use the printit.exe utility to print this pdf, german umlauts are replaced by a strange symbol character, same bitmap issues...

    Please check what kind of PDF you have. I saw pretty corrpted PDF files, mostly by wrong settings in ghost script based printer drivers.

    Hi,

    Well I was just checking out the demo with a few PDFs I have here and was wondering why I found so many problems (sorry).

    I didn't read about the limitations yet, I am looking for a possibility to display pdf's embedded in a Delphi application. Not all pdf's will be generated out of my software, so the limitations may hit several times...

    Sorry to be rather negative, but I have to say the display bugs disappointed me a bit... I'm not sure if I will buy wpViewPDF.
