Before revision: A better description of the A, D, B and E parameters is: Line 1: A: x-component of the pixel width (x-scale) Line 2: D: y-component of the pixel width (y-skew) Line 3: B: x-component of the pixel height (x-skew) Line 4: E: y-component of the pixel height (y-scale), typically negative Line 5: C: x-coordinate of the center of the original image's upper left pixel transformed to the map Line 6: F: y-coordinate of the center of the original image's upper left pixel transformed to the map All four parameters are expressed in the map units, which are described by the spatial reference system for the raster.
