[mapserver-users] Support for PNG Symbols

[Referencia SA]

Thanks Scott for kind reply, i am submitting the question again to the list
to see if some one else have a clue....

Hi every one

Finally we have mapserver running. We didn't install .gif support, only .png
installed.



 We are playing with itasca demo, and  have changed all .gif to .png  how
ever we get the following error:
 msLoadMap(): General error message. Undefined symbol "symbols/ctyhwy.png"
in class 0 of layer ctyrdln3_anno.

Can the symbols be .png or they must be .gif? If above possible, how to
avoid error?



Off course, if class for symbol is commented (#) the demo runs ...
