[mapserver-users] color range fade to transparent.

[Robert Sanson]

Hi Bob

You need an alpha (opacity) value that would go from 1 to 0. 

Can you set an opacity value in your database as an attribute that is calculated from age? Then maybe you could set the OPACITY in your layer to read it from the database column?

Your output format should support RGBa values, so GIF or PNG.

Cheers,

Robert

All,

Anyone know how to use a transparent color on one end of the coloring option?

COLORRANGE 255 0 0 ??? ??? ??? ## red -> transparent

It there a RGB color to use for Transparency to fade to?  I basically want to fade a line based on age to nothing.

Thanks

bobb
