 sorry, first do cvs update for libgdiplus, then copy the line I have
 given above and then build libgdiplus.

 About Color.Green, we should use the same as MS does. I sent an email
 to ravindra on this.

+I have added the printf command to the latest libgdiplus source. Here are the results from 
+the tests. The first line displays the ARGB properties of the managed Color structure, the 
+second the output from the new printf line. So far everythings seems to be in order. I fear 
+the error is in far deeper regions.
+
+Blue:
+Mono Color value: A=255, R=0, G=0, B=255, argb=-16776961
+libgdiplus: a=255.000000, r=0.000000, g=0.000000, b=255.000000
+
+Red:
+Mono Color value: A=255, R=255, G=0, B=0, argb=-65536
+libgdiplus: a=255.000000, r=255.000000, g=0.000000, b=0.000000
+
+Green:
+Mono Color value: A=255, R=0, G=128, B=0, argb=-16744448
+libgdiplus: a=255.000000, r=0.000000, g=128.000000, b=0.000000
+
+I also did a test with Color.Green on the Microsoft Framework. The ARGB value is exactly 
+the same as in Mono.
+BTW with the latest libgdiplus version, the bmp.Save() methods throws an exception now. 
+But this seems totally unrelated. I first want to test some other things before submitting a 
+bug here.
