Re: [mapserver-users] RGBA transparent images?
Hi Steve, I have this in my file: OUTPUTFORMAT NAME AGGPNG DRIVER AGG/PNG EXTENSION png MIMETYPE image/png;mode=24bit; IMAGEMODE RGBA FORMATOPTION INTERLACE=true FORMATOPTION QUANTIZE_NEW=ON FORMATOPTION QUANTIZE_FORCE=ON FORMATOPTION QUANTIZE_DITHER=ON FORMATOPTION QUANTIZE_COLORS=256 END And in my layer, if you want opacity: OPACITY 60 That should render nice lines :).

Erm, pick interlace=false instead.

[mapserver-users] RGBA transparent images?
If I want to generate RGBA transparent images using AGG, what should my OUTPUTFORMAT block look like? I was using this one for 8-bit images, but the anti aliasing was creating blackish artifacts along the rendered lines. Is there a way to avoid them?
