In Mapscript 3.6, the saveImage method had a parameter that allowed the
transparent color to be specified.
$img = $map->draw();
$img->saveImage($imgfile, MS_GIF, hexdec('FFFFCC'), 0, 0);
I'm porting to 4.8.2 and still discovering differences in the object model.
The following lines seem to get me a gif, but how do I tell it which color is
transparent?
$map->selectOutputFormat('gif');
...
$img = $map->draw();
$img->saveImage($imgfile);
Thanks for your help.
