[mapserver-users] Background color using PHP/MapScript.

[Rob Martinson]

Beau,

I wrote parameters for the saveImage line incorrectly in that .phps. I
think what is happening is it's setting color index 90 to transparent
which allows your background to show through (maybe? Just a guess, I
know my line is incorrect). Try changing line 82 of buildmap.php from:

$img->saveImage("",MS_PNG,90,0, 0);

To: $img->saveImage("",MS_PNG,MS_FALSE,MS_TRUE,-1);
