<br>
I make the path for polygon A, stroke it, fill with red, and apply "Long Label<br>
A" using pango. Next, I stroke polygon B, fill with blue, and apply "Label B".<br>
Everything is great, expect the polygon B fill overlaps and hides part of "Long<br>
Label A" text.<br>
<br>
<br>
-----------------------<br>
| Long Label A |<br>
| | Label B |<br>
-----------------------<br>
A B<br>
<br>
How do I always keep the text in the z-order foreground? I already know about<br>
decreasing font size and making the labels appear on multiple lines to prevent<br>
overlaps. I'm looking for something to use when overlap cannot be prevented. I<br>
tried using alpha channel, so the label can show through, but I lose too much<br>
intensity for both text and fill colors.<br>
<br>
<br>
In other words, is there a way to tell cairo / pango "I want this text to always<br>
be foreground", or "I want this fill to always be background".<br>
<br>
If not, is it possible (or advisable) to write the polygons to one context (I<br>
guess), write the text to another context (or whatever), and then overlay the<br>
text over the polygons? If this is feasible, could someone sketch out the key<br>
functions to use.<br>
<br>
Perhaps I will end up doing all the polygons first, and then doing all the<br>
labels. It's just inconvenient, since I get all the data for one polygon, its<br>
label and the label positioning, then get all the data for the next polygon,<br>
etc.<br>
<br>
<br>
I'm not saying the default behavior (fill overlays previous text) is wrong. I'm<br>
just hoping I can override it. I looked through the cairo and pango docs and<br>
past postings and couldn't find the answer.<br>
<br>
<br>
Thanks,<br>
Daniel<br>
