[mapserver-users] Problems with png output when using libpng 1.5

Hi,
I compiled MapServer 6.0 beta6 against libpng 1.5.2 and encountered the
following problems:
* when using the default png IMAGETYPE (i.e. no OUTPUTFORMAT block),
I got yellow & striped maps (see cyprus.png)
* when using the AGG/PNG driver and IMAGEMODE "RGBA", the output
image looks fine
* when using the default png8 IMAGETYPE, the output image looks fine
I also compiled with cairo, and with the driver set to CAIRO/PNG, I had
the same yellow & striped maps.
With libpng 1.2.44, everything seems to work properly. Has anyone else
seen this problem with libpng 1.5? Should it work properly with MapServer?
Regards,
Christy
