[UMN_MAPSERVER-USERS] How to create tiles accurately with MapServer?

[Teemu Mäkelä]

Hi,

I should create tiles. I have linear features and in mapfile I've defined the line to be drawn with width of 1 pixel.

On the border of tiles:
CASE A:
- Line continues OK from tile A to tile B, if line crosses the tile border with angle of 45-90 degrees.
CASE B:
- Line does not continue (small gap), if line crosses the tile border with angle of 0-45 degrees. Gap is the problem! Size of the gap depends on the angle. If angle is 5 degress, gap is about 10 pixels; if angle is 30 degrees, gap is about 3 pixels.

Any idea how to get rid of the gaps on lines?
