Description
Starting with Mapserver 4.10.0 truetype font outlines appear to be broken. Each character outline now shows up as multiple outlines offset randomly, making it difficult to read the text or interpret symbols. Truetype font outlines worked fine with Mapserver 4.8.4. Here is a sample mapfile demonstrating the problem: MAP SIZE 500 200 EXTENT 0 0 100 100 FONTSET "{path to fonts}/fonts/fonts.list" IMAGECOLOR 0 0 0 OUTPUTFORMAT NAME png DRIVER "GD/PNG" MIMETYPE "image/png" IMAGEMODE RGB EXTENSION "png" END PROJECTION "proj=latlong" END LAYER TYPE ANNOTATION FEATURE POINTS 50 65 END END STATUS DEFAULT CLASS TEXT "TRUETYPE FONT;Mapserver-4.10.0" LABEL TYPE TRUETYPE FONT courier SIZE 35 POSITION CC COLOR 255 0 0 OUTLINECOLOR 255 255 255 WRAP ';' END END END END

Example using Mapserver 4.10.0, text outline has problems.

Yup, that FUBAR. I've not seen the same problems with any of my 4.10 applications. What versions of GD and Freetype are you using? Steve

I tried both gd-2.0.33 and gd-2.0.34, freetype-2.3.1 and the version included with the Redhat distribution(libfreetype.so.6.3.7). Makes no difference. I'm building both mapserver 4.8.4 and 4.10.0 identically using the same versions of dependent software. Version 4.8.4 works fine but 4.10.0 does not. Did you try using my test mapfile? And did it work for you? The problem is not obvious if you are using small fonts so could the problem be there but you just overlooked it?? The problem is particularly troublesome to me since I'm using a large ship outline symbol to plot the location of a ship and starting with version 4.10.0 the ship is no longer recognizable. I'm using this font in a label so could it have something to do with maplabel.c? I've noticed you made a lot of changes to this file since mapserver 4.8.4 to support curved labels. -Steve

I can confim the bug on my end. I'm puzzled why this hasn't been noticed before. Perhaps since folks don't often render 35pt text. For example, if you reduce your size to 10 you don't see the effect, but larger and you do. All my 4.10 interfaces stick to relatively small text sizes. I suspect the problem is in mapgd.c since that's where the outline is applied. Working on it, should be an easy one (I hope)... Steve

Ok, found the problem. I suspect this cropped in when some other changes were contributed by a third-party and I simply didn't scrutinize them closely enough. I have fixed the error in 4.10 branch and CVS HEAD... Steve

Example using Mapserver 4.8.4, this is OK
