[mapserver-users] MS 6.0 beta6 and faulty image/png; mode=8bit output if source image has overviews

[thomas bonfort]

Erik,
the png compression that is applied is now configurable, and defaults
to "6". You can set it as it was by default in 5.6 for quantized
output with
FORMATOPTION "COMPRESSION=9"

please post your image size after the change.
