A major issue has cropped up with the handling of raster data in composer output. Rasters appear to be rendered multiple times with a datum shift at each render. I've attached an example I made using the spearfish data (geology raster layer and archsites vector layer). This should be replicable, but testing by others would be appreciated. I used default settings for the composer item (A4, landscape page). Printing as raster, vector, exporting as image—all have the same result as shown below.

I realized my test example was being reprojected to epsg 26911. Setting the native resolution as the project default generates the same general problem. Likewise, turning off OTF reprojection results in bad map output.

#2 Updated by Anita Graser about 12 years ago

I confirm this problem on Ubuntu with a3cfe6fb (SVN r15506).

#3 Updated by John Tull about 12 years ago

I was able to get a successful map produced with rev 15382, but nothing beyond that (there were separate crash issues for OSX not resolved on my platform until rev 15412, so it may have cropped up anywhere in that span of code updates).

#4 Updated by Marco Hugentobler about 12 years ago

  • Resolution set to fixed
  • Status changed from Open to Closed

Should be fixed in 7d42434d (SVN r15529). Please test and reopen if not.
