#145 closed enhancement (fixed)

Labelling: Please enhance cartographic text output

While the text placement in MapGuide TNG is generally pretty good, there are several cases where it really breaks good cartographic practice.

In particular:

  • There does not seem to be any preference applied to the orientation of line segments. Often, text will be placed on a curve in the middle of a line, rather than on a relatively straight segment.
  • Sometimes text appears upside-down. I believe that this occurs when placing multiple labels on a single line segment that curves signifigantly.

I'm attaching images illustrating these cases. This is on MapGuide 1.1.0, so maybe it's already been fixed :)

I should note that although these examples look like polygon labels, they are actually labelling an invisible street centerline.

The upside down label problem has been addressed by the fix to ticket #196

Just confirming that the upside-down problem works fine with 2.0.0, and that it still does not seem to prefer straight segments for labelling.

Should I close this request and open one that addresses the second issue specifically?

Closing in favour of #351, which describes the same "prefer straight segments" problem in more detail.
