#760 closed defect (fixed)

re-projected rasters have lines where the grid triangles meet

Reported by: tonyfang Owned by: tonyfang
Priority: medium Milestone:
Component: Rendering Service Version: 2.0.1
Severity: minor Keywords:
Cc: External ID: 1147564

Description

Using Studio...

  • Using Load Procedure: add a raster image, specify the appropriate coordinate system
  • add the resultant layer to a map
  • change the map's bg color to something that contrasts with the raster image
  • change the map's coordinate system to something else (invoking raster re-projection)
  • preview the map

--> notice there are faint lines where the grid triangles meet

It is AGG’s anti-aliasing that is causing the grid-lines.

When I change the calls from render_scanlines_aa (aa = anti-aliasing) to render_scanlines_bin, the grid lines disappear.
