crosshatch

[Steve Lime]

At the moment you can't change the thickness of the lines. It's not that it's impossible, it's just that the styleObj doesn't have enough specificity to support it. What's needed is a second size related parameter. I would propose 'THICKNESS' which would control the thickness of what are now single pixel width lines: lines with no symbol, hatch lines, vector symbol renderings and so on. This would remove the requirement of defining a circle symbol to draw 'fat' lines (although that would still work). You'd just need something like:

STYLE
  COLOR 255 0 0
  THICKNESS 4
END

Note that the new hatching work Arnulf and I did allows for arbitrary hatch angles and does not allow for thick lines. SIZE controls the spacing. This is not a particularly difficult addition for GD, not sure about PDF and SWF output.

Hey John,
send a request for this to arnulf.christl at ccgis.de or to steve lime.
They develloped this graphic feature just a short time ago and normally
it should be allredy integrated in the current code of relese 4.4.
Kind regards,
Peter
