rfc33_gtiff_pixelispoint
v4 v5 37 37 Folks have at various points in the past requested that we report the extents differently for files with an AREA_OR_PIXEL value of PIXEL, must as listgeo does for GeoTIFF files that have a !PixelIsPoint interpretation. I do *not* plan to do this, and for the purpose of GDAL the GCPs, RPCs and !GeoTransform will always be based on an area interpretation of pixels. The AREA_OR_PIXEL will *only* be used to control setting of the !PixelIsPoint value in GeoTIFF files, and as metadata about the physical interpretation of pixels. 38 38 39 == World Files == 40 41 These changes will have no impact on how world files are treated or written. They are always based on the assumption of a area based pixel, but with the origin at the center of the top left pixel. This is effectively the same as the values for PixelIsPoint, but is not in any way tried to this metadata. 42 39 43 == Test Suite == 40 44
