on top. Erased its background to let the bottom one come visible.<br>
Then filled it with a pattern, and then had grads merge both layers<br>
and save the composed image.<br>
<br>
Quite time consuming, but it worked for me.<br>
<br>
Another option could be using PyGrads to rely on python<br>
graphical capabilities.... Never done it, but maybe it has<br>
pattern filling.<br>
</blockquote><div><br>And yet one more option is to use gxyat to create SVG instead of PNG and pop that into a vector graphics application such as Adobe Illustrator or Inkscape. The advantage of vector graphics is that you do not loose any resolution.<br>
<br>If you know C, and are willing to learn the cairo library, you could extend gxyat and allow the user to substitude specific colors with specified fill patterns. Drop a note at <a href="mailto:opengrads-devel at lists.sf.net">opengrads-devel at lists.sf.net</a> if are interested in working on gxyat.<br>
