Ticket #232 (new defect)
raster and vector mismatch in monitors
|Reported by:||hcho||Owned by:||grass-dev@…|
I used r.to.vect to convert a raster map to vector and displayed both of them on a monitor. When the monitor is in the default size, I can see slight mismatch along the boundaries of the two maps. For example,
r.to.vect input=tmp output=tmp feature=area
d.vect tmp type=boundary
If I zoom in a lot or make the monitor larger, I don't see this effect. My guess is that conversion between raster and vector was OK, but scaling coordinates (R_scaled_raster or something?) before actually displaying them might cause this problem. In effect, PNG maps exported from the monitor looks so ugly.
I'm attaching two figures (small and large monitors).
