And one additional comment... If you are compiling the server yourself
and willing to try new things, you can locate the function:

MgByteReader* MgServerRenderingService::RenderMap(MgMap* map,
                                                  MgCoordinate* center,
                                                  double scale,
                                                  INT32 width,
                                                  INT32 height,
                                                  CREFSTRING format)

In ServerRenderingService.cpp around line 400 and in there change the

    GDRenderer dr(width, height, bgcolor, true);


    GDRenderer dr(width, height, bgcolor, false);

This should make your GETMAPIMAGE generated tiles look a lot more like
the tiled AJAX viewer (GETTILEIMAGE) tiles at the expense of some

Hi Velen,
Also, have in mind the comments I posted in the "Tiled Map" thread at:

The AJAX viewer uses GETTILEIMAGE, so if you want your tiles to look the
same then that's the API you need to use.  GETMAPIMAGE was not designed
for use in a tiled context.

We were able to generate tiled map using GETMAPIMAGE from a .net windows
form; below is the screen shot. As you can see, in the sample Sheboygan
map, some "District" numbers were chopped off in the same tile or showed
in the adjacent tiles. I understood this is probably because each tile
get rendered individually, but is there a solution for making tiles look
likes what ajaxviewer does?


Thanks for your help in advance,
