[MS4W-Users] [ms4w-users] agg + transparency + quantize not working

[G. Tiemens]

I am busy writing a application with mapscript in C#.

Currently I am facing the earlier mentioned problems of agg + transparent
images + quantization.
Is the new MS4W compiled with the quantization options?

The image background is now Black. The labels are dissapearing.
It should be an image wich is completly transparent with some colored lines
and some black labels.

Setting the imagecolor will not help me.
Images without quantization options on, are perfect and beautiful png's.


What I am using now is this:
MS4W 3.0 Beta 7    
C# mapscript


Mapfile is completely written in C#, so all default options apply.
I saved
