I'm soliciting for some ideas regarding patterns in SVG. The
document is basically a thematic diagram created on the fly
using .net. Rectangles in a layer need to be filled with a pattern
based on the coded lookup value of that particular shape. Examples
of patterns are hatching, cross-hatching, etc. Secondly -the part
I'm struggling with- is that the color of the pattern needs to be
based on a lookup value also. As far a I can tell there's no real
efficient way to do this without creating multiple patterns with all
the various fill color options. For example:
defs>
<pattern id="checkerPattern" patternUnits="userSpaceOnUse"
x="0" y="0" width="20" height="20"
viewBox="0 0 15 15" >
<rect x="0" y="0" width="10" height="5" fill="blue"/>
<rect x="5" y="5" width="15" height="5" fill="blue"/>
</pattern>
</defs>
That code would work just fine if I only wanted a blue checkerboard
pattern. However, the color and pattern type needs is determined
based on a lookup value in the database. I can do the patterns
easily enough since there are only a half-dozen or so options. The
fill colors on the other hand can range the entire span of RGB.
Obviously loading all the fill color vairiations per pattern isn't
an option. Any thouguhts would be apreciated.
Thx,
bmc
