hvHTML don't show pdf in Linux

  1. 4 months ago

    for pdf converted from tiff

    hvHTML.LoadPage fi

    works on my MacOSX 10.12.4

    but it doesn't work

    on my Ubuntu 14.04 LTS

    How can I still show it within my mainWindow

    Again Safari and the underlying engine on OS X has support for things that most browsers don't because of the support that CoreGraphics gives Safari
    So while most major browsers and underlying engines do not support PDF or TIFF ( see https://en.wikipedia.org/wiki/Comparison_of_web_browsers#Image_format_support ) Safari does

    I'd use PNG or JPG

    If you have imagemagick installed on Linux it may be able to convert the TIFF to a JPG or PNG

    PDF viewing is not built into the HTMLViewer itself
    On OS X The underlying OS control has a way to do this
    On Linux it does not

    You'd need "something else" to

    • maybe turn the PDF into an image
    • a plugin likeDynaPDF to open & show the PDF

    Or simply display the TIFF, and not turn it into a PDF in the first place ...

  4. TIFF file displaying with HTMLViewer1.LoadPage fi works on Mac but doesn't
    work on Linux
    is it possible to wrap in <html tags>
    Anybody have a simple example?

  7. i'm able to convert the files in terminal with mogrify/convert from the imagemagick package
    but it splits multiple pages in different files, so i have to handle it twice (png_view and pdf_store)

    Thanks for your advice
