<div>I'm using ellipse or vector type symbols for the hatch, not pixmap, but "TRANSPARANCY ALPHA" is set within my layer, which allows the blank parts of the hatch to be seen through. </div>
<div> </div>
<div>Previously you also had to set transparent on in the outputformat or else transparancy alpha within the layers failed. Going further back in time, transparent on used to be set outside the outputformat block at the top of the mapfile for the same effect.
<br> </div>
<div>But I guess this is all moot since transparancy alpha works properly now without transparent on in the outputformat. Hopefully our conversation will point others in the right direction if they encountered the same issue.

<br>From the mapfile-reference.html:<br><br>---<br>The "ALPHA" symbol directs the mapserver rendering code to honor the<br>indexed or alpha transparency of pixmap symbols used to style a layer.<br>This is only needed in the case of RGB output formats, and should be
