[Grid] Grid layer don't display rounded values when zoomed in
|Reported by:||jlacroix||Owned by:||mapserverbugs|

Grid layers seem to define the place where they draw the grid on the map on in weird way when zoomed in. It seems that when we are zoom-in to display less than a degree on the map, the place where the grid layer place its grid lines is all messed up. Below is a sample mapfile to reproduce this problem. If you notice, the -87 degree is in the middle of the image. However, mapserver place the line of the grid on -86D 56M 59S. MAP STATUS ON SIZE 400 300 EXTENT -87.052494 49.738376 -86.925045 49.972017 WEB TEMPLATE "testmap.html" IMAGEPATH "/tmp/ms_tmp/" IMAGEURL "/ms_tmp/" END LAYER NAME "gridlayer" TYPE LINE STATUS DEFAULT CLASS COLOR 0 0 0 LABEL COLOR 0 0 0 SIZE SMALL OUTLINECOLOR 255 255 255 END END GRID LABELFORMAT "DDMMSS" MININTERVAL .25 END END # Layer END # Map File To add on the top of that, if you change the MININTERVAL to 1, there's no line at all. Even if the -87 degree is right in the middle of the map.
