<p class="MsoNormal"><span style="font-size:8.0pt;font-family:"Comic Sans MS","serif"">I thought of an easier way to ask my question about a capability being removed in recent Mapserver.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:8.0pt;font-family:"Comic Sans MS","serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:8.0pt;font-family:"Comic Sans MS","serif"">How can a Pick a RGB color and use that as a TRANSPARENT piexel value across the whole image, doesn’t matter if the color is the background color, or a feature color. I
just want to make a particular color transparent.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:8.0pt;font-family:"Comic Sans MS","serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:8.0pt;font-family:"Comic Sans MS","serif"">It doesn’t look like I can set transparent to TRUE without the background going transparent. What I’m after is drawing a feature layer (polygon) as transparent. Is there
a way of setting a layer element transparent??<o:p></o:p></span></p>

<p class="MsoNormal" style="margin-left:.5in"><span style="font-size:8.0pt;font-family:"Comic Sans MS","serif"">All,<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-left:.5in"><span style="font-size:8.0pt;font-family:"Comic Sans MS","serif""><o:p> </o:p></span></p>
<p class="MsoNormal" style="margin-left:.5in"><span style="font-size:8.0pt;font-family:"Comic Sans MS","serif"">So I used to be able (MS6.1 and older?) to just define a color and then set transparency to ON, and that color would be transparent. It didn’t matter
if it was the background or a feature that was drawn in that color, it just turned transparent.<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-left:.5in"><span style="font-size:8.0pt;font-family:"Comic Sans MS","serif""><o:p> </o:p></span></p>
<p class="MsoNormal" style="margin-left:.5in"><span style="font-size:8.0pt;font-family:"Comic Sans MS","serif"">I have a slightly different use case than most users as. I want to maintain a background color for the image, but filter out polygons (parcels)
to be transparent in color (not opaque) as an overlay. This is to represent all Public right-of-way areas, or rather, areas that are NOT parcels.<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-left:.5in"><span style="font-size:8.0pt;font-family:"Comic Sans MS","serif""><o:p> </o:p></span></p>
<p class="MsoNormal" style="margin-left:.5in"><span style="font-size:8.0pt;font-family:"Comic Sans MS","serif"">I’ve been trying for a couple of days now on and off to make the new methods replicate this capability, to little effect. All the new tools assume
a transparency is going to be applied across the whole image background. I need to be able to only poke holes in the background where there is a parcel polygon.<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-left:.5in"><span style="font-size:8.0pt;font-family:"Comic Sans MS","serif""><o:p> </o:p></span></p>
<p class="MsoNormal" style="margin-left:.5in"><span style="font-size:8.0pt;font-family:"Comic Sans MS","serif"">Is there a way to make this work like in the good old days (I mean good old versions ?? :c) of Mapsever??<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-left:.5in"><span style="font-size:8.0pt;font-family:"Comic Sans MS","serif""><o:p> </o:p></span></p>
<p class="MsoNormal" style="margin-left:.5in"><span style="font-size:8.0pt;font-family:"Comic Sans MS","serif"">One suggestion I did find that would likely work, was the use a mask, but then I need a larger bounding area to contain the mask (Is there a way
of defining an edgeless mask??). Is this the track I should be persuing? I could use our City Boundary for this as a possible solution. Also, what’s all the stuff about a COMPOSITE block, looks like this is the future of masking type operations in the future.<o:p></o:p></span></p>
