Symbol File Problem - Clipping

[plasmab]

Using mapserver i need to render a diagonal patterned fill with a 15px spacing between lines, and a pattern line width of 1px. The following symbol *used* to work on version 4.4.2

SYMBOL

NAME "mapinfo-brush-5" TYPE vector POINTS

0 1 1 0

END

END

I can get a close approximation of the required effect with :-

SYMBOL

NAME "mapinfo-brush-5" TYPE vector POINTS

0 15 15 0

END

END

However the brush fill is not clipped to the extent of the polygon. i.e. The brush draws outside the poly, which it should not do.

Can you confirm this is indeed an AGG problem and that it works for GD? That will help determine who sees the bug.

I erred when filling out the bug report. Problem is for GD.

I just tried this and it worked ok for me with a simple triangle feature. See:

​http://maps.dnr.state.mn.us/~stlime/test_2110.gif

I can vary the spacing using the SIZE element in a STYLE. Here's the mapfile I used:

MAP

NAME 'bug2110' EXTENT 0 0 1000 1000 SIZE 500 500

SYMBOL

NAME 'hatch' TYPE VECTOR POINTS 0 1 1 0 END

END

LAYER

NAME 'test' TYPE POLYGON STATUS ON FEATURE

POINTS 50 25 400 700 900 300 50 25 END

END CLASS

STYLE

COLOR 255 0 0 SYMBOL 'hatch' SIZE 15

END

END

END

END

So, I guess I don't see the problem. Note this is using the main svn branch with GD 2.0.34.

Is there more information you can provide (test case with data and a mapfile?)...

tile joining with vector symbols cannot be obtained with antialiased renderers. use the HATCH symbol that is designed for this case.
