<P><FONT SIZE=2 FACE="Arial">The fact that the existing MapGuide 6.5 and below does not support this has been a major problem for several of my clients. The problem that arises is that tiled imagery is often obtained from a source in one coordinate system and then is transformed to the desired map coordinate system. This results in black "wedges" along all of the edges of the resultant orthogonal image. MapGuide 6.5 does not allow you to specify a null color value (to non-bitonal images) so when image tiles are viewed together, the sliver from one image blocks part of another image. To get around this, the clients have had to spend a large amount of time, resources and money (for special image software) pre-processing the imagery. We end up having to mosaic the projected images and then tiling back out into orthogonal pieces.</FONT></P>
