Re: [png-mng-misc] fuzzy, bad quality of png files rendered with v 1.6.2

[John B. <joh...@gm...>]

Questions relating to libpng, as opposed to the PNG file format, need to be
asked on the png-mng-implement list, however in this case I suspect this is
an issue with the change to GeoMOOSE.  It's quite possible that GeoMOOSE
does everything using just 256 colors, and it's quite possible that
shp2img  changed in its handling of 24 bit rgb in the mapserver bump from
5.x to 6.x

I suggest you repost on png-mng-implement and include a sample mapfile, the
shp2img command that the new output.  Ideally if you have it include the
original output, but in any case include the output when the image format
is set to JPEG.

Unfortunately I can't get shp2img to work - it just fails on the test.map
mapfile with "loadProjection(): Projection library error. Projection
support is not available. <br>", anyway test.map doesn't have any PNG files.
