[mapserver-users] Error MsDrawMap Image handling error when using PNG

[Gerhard Völkl]

Hello,

when using a png image as symbol I got the error

Image handling error

When using a gif image all is fine.
But I can’t change all 1000 Images to gif.

What can I do? Whatˋs wrong?

Here an example Output:
