[mapserver-users] Lost the transparency after a SO Update

[Andrea Peri]

The "#ffffff01" sintax was dismissed ?

The 7.4.2 docs don't report this.


------ from https://www.mapserver.org/mapfile/style.html
-

RGBA value (adding translucence): “#rrggbbaa”. To specify a
semi-translucent magenta, the following is used:

COLOR "#FF00FFCC"

-------

I try this sintax with OPACITY.

Thx,
A.
