[Mapserver-users] legendObj outlinecolor property does not exist?

Daniel,
Thanks, but apparently it still does not display an outline around the legend,
but something did mess with my truetype on a different class object. My
truetype support died on the labelObj of scalebarObj...still works fine on
the labelObj of the legendObj (already tried a few minsize-maxsize scalings).
I get an error in the Apache error_log: PHP Fatal error: MapServer Error in
msGetBitmapFont(): Invalid bitmap font. Must be one of tiny, small, medium,
large or giant.
The scalebarObj label is exactly the same (even copy-pasted) as the legendObj
label but gives me this error. This file is the only code I've messed with
(font scaling worked fine before on both major objects), so I think it may be
tied somehow to modifications to the ColorObj's. I don't know...just wild
stabs in the dark.
This script works great, but doesn't render an outline around the legend.
/* BUILD LEGEND */
$my_legend = $map->legend;
$my_legend->set(height, 80);
$my_legend->set(width, 160);
$my_legend->imagecolor->setRGB(240,220,200); # tan
$my_legend->outlinecolor->setRGB(1,1,1); # black
$my_legend->set(status, MS_EMBED);
$my_legend->set(position, MS_UL);
/* SET LEGEND LABEL PROPERTIES */
$my_lg_label = $my_legend->label;
$my_lg_label->set(font, "arial");
$my_lg_label->set(type, MS_TRUETYPE);
$my_lg_label->set(size, 10);
$my_lg_label->set(minsize, 6);
$my_lg_label->set(maxsize, 12);
$my_lg_label->color->setRGB(100,100,100);
$my_legend->set(postlabelcache, MS_TRUE);
/* DRAW LEGEND */
$map->drawLegend();
This script generates the BITMAP error indicated above.
/* BUILD SCALEBAR */
$my_scalebar = $map->scalebar;
$my_scalebar->set(height, 6);
$my_scalebar->set(width, 300);
$my_scalebar->set(intervals, 10);
$my_scalebar->set(units, MS_KILOMETERS);
$my_scalebar->set(status, MS_EMBED);
$my_scalebar->set(position, MS_LC); # lower center
$my_scalebar->color->setRGB(200,10,10); # maroon
$my_scalebar->backgroundcolor->setRGB(10,100,10); # evergreen
$my_scalebar->outlinecolor->setRGB(255,255,255); # white
$my_scalebar->imagecolor->setRGB(20,255,90); # bright green
/* SET SCALEBAR LABEL PROPERTIES */
$my_sb_label = $my_scalebar->label;
$my_sb_label->set(font, "arial");
$my_sb_label->set(type, MS_TRUETYPE);
$my_sb_label->set(size, 10);
$my_sb_label->set(minsize, 6);
$my_sb_label->set(maxsize, 12);
$my_sb_label->color->setRGB(100,100,100);
$my_scalebar->set(postlabelcache, MS_TRUE);
/* DRAW SCALEBAR */
$map->drawScalebar(); # <--- ERROR ON THIS LINE
So, in summary, It looks like labelObj's attached to ScalebarObj do not like
MS_TRUETYPE as a type, or the integer style property is mandatory, regardless
of type, or I'm in over my head.
Thanks...this is getting interesting.
