  • Component changed from default to GDAL_Raster
  • Keywords vrt added
  • Milestone set to 2.1.2
  • Owner changed from warmerdam to rouault
  • Version changed from unspecified to 2.1.0

When using non-nearest resampling, currently all sources are opened to check if their nodata value matches the nodata value set at the VRT band level. Instead of just trying on the sources that intersect the requested window.
