Wrong/different legend generation

[Dejan Gambin]

Hi,

I am using GetLegendGraphic request for generating legends in my OL application. Everything was fine in previous MapServer version 6.0.3. The request like this:

http://my.site.com/cgi-bin/mywms6?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetLegendGraphic&FORMAT=image/png&LAYER=my_layer

returned an image like in attached image1.png. The same request in 6.4.1 returned an image like in attached image2.png. The legend part of mapfile is:

LEGEND
OUTLINECOLOR 194 194 194
KEYSIZE 25 18
KEYSPACING 8 5
LABEL
COLOR 255 0 0
FONT Arial
SIZE 8
TYPE truetype
OFFSET 0 -5
END
END

Is it a bug or should I hopefully just configure things differently?

Thanks very much

regards, dejan

Does anyone have a clue about this? Not sure if this is a bug or not :-(

thx, dejan

Certainly looks like a bug but it would help to see the layer defs for one of the solid fills layers and one of the line layers. Are you setting map resolution explicitly? --Steve

Here it is:

Solid layer example:

CLASS
Name 'Golf, sport and recreation'
EXPRESSION ('[namjena_oz]' eq 'R' OR '[namjena_oz]' eq 'R1' OR '[namjena_oz]' eq 'R2' OR '[namjena_oz]' eq 'Rt' OR '[namjena_oz]' eq 'PN+R' OR '[namjena_oz]' eq 'R2/R6')
COLOR 0 255 0
OUTLINECOLOR 0 0 0
END


Line layer example

CLASS
Name 'City'
STYLE
COLOR 250 0 0
WIDTH 3
END
END


But this all doesn't seem to be the problem as it happens on all possible layers. Decreasing font size helps in a way the legend text is smaller but it still "doesn't fit". Take a look on attached picture (font size 6 and 8, text is cut)

I have resolution explicitly set to 96.

I believe I didn't send the answer to the list. So, yes it works in this case. Is it then a bug and should I report it?

Same problem here.
With FONT Type bitmap the legend Image is correctly sized.
Maybe some bug with calculating the font metrics of true type fonts.
