Remarks

Supported image formats include: BMP, JPG, DIB, TIFF, PNG, PNG24, PNG32, EMF, PS, PDF, GIF, SVG and SVGZ.  When a PNG24 image is requested from MapServer and in the same request specifies a transparent color, a 32-bit PNG is returned in order to support the transparency.  The transparency is within the alpha channel and only supports only binary transparency.

However PNG32 image format supports with full alpha channel transparency. PNG32 maintains transparency in the image that is set on the layer in the source map. To find out what image formats are supported by a map service, use the IMapServer2::ServiceConfigurationInfo property.
