[mapserver-users] Differnet Quality Output of Text labels

[Stephen Lime]

Again this is because the GD/Freetype integration doesn't process un-antialiased text correctly. There is no fix short of hacking GD or getting the GD group patches that fix the problem. They are open to that but I've not had the time to create them.

The best thing to do is to just use ANTIALIASing whenever you use TrueType fonts. Since the extra colors necessary are allocated at the end of rendering there is little impact on the actual output, nor is there much of a performance hit.

Hello Group!

After transfering my application from a old server to a new one the 
following problem appeard with the text labels in the maps:



I have on both servers Mapserver 3.4 running with gd 1.2, so the outputs 
are GIF images. The only difference is that on the old server i have 
compiled PHP 3.0.18  with True Type Support and on the new server i have 
compiled PHP 4.0.5 without True Type (as told in the documentation) . 
But i have included True type to the Mapserver compilation. When i leave 
this paramter the demo wont work, because the Mapserver didnt know the 
TRUETYPE Tag in the Mapfile, so i know that it should work correctly.

This problem looks simmilar to the problem S(tepán Kafka wrote some 
postings ago, but i dont use 3.5 yet.

I have read Stevens answer to the post, but i dont know what can i do 
against this issue between GD and Freetype.

I hope anybody can help me. (So that i can give away the old server 
soon.)  ;-)
