In python mapscript, I am creating a pixmap symbol from a gif. I am =

I am pretty sure that I need to set a color or background color, but =

Here is what I am trying:=20
# add the image symbol we defined above to the inline layer
cls =3D mapscript.classObj(inline_layer)
cls.name=3D'classname'
style =3D mapscript.styleObj(cls)
style.symbol =3D mymap.symbolset.index('from_img')
style.backgroundcolor.setRGB(-1, -1, -1)
style.color.setRGB(-1, -1, -1)
Thanks,=20

If your GIF is properly transparent, all you have to do is set the
transparency property of your layer
layer.transparency = mapscript.MS_GD_ALPHA
