    Wink [Fix] poor quality of exporting Dia diagrams into .png format

    If some of you actually try Dia - a simple software for creating diagrams, a visio alternative (a very simplistic one) and after all the work finds that the exported .png file has very low quality this is how to fix it:

    It seems that when exporting with Dia if you do:
    Under "File->Export..." in the dialog select: "Determine file type: By
    extension" and under "Name: " put something like "test.png"
    the final .png has poor quality, and no antialiasing is used.

    But by doing:
    under "File->Export..." in the
    dialog select "Determine file type: Portable Network Graphics (*.png)" and
    Under "Name: " put something like "test2.png"
    Now a window will ask about image size, just click "ok".
    the final .png now is antialiased and the quality is perfect!

    I described the bug here with a simple example: http://bugzilla.gnome.org/show_bug.cgi?id=535179

    If someone can reproduce this I would appreciate to comment on the bug. Thank you.


    I actually lost several hours trying to fix this so I hope this will be useful in saving your time...

    I can report repeating this in Ubuntu 8.10 with Dia 0.96.1.

    Thanks for the information, it is very helpful to me.
