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

[Gerald Buckmaster]

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.

Gerald
