gdalwarp: suboptimal clipping
|Reported by:||hamish||Owned by:||warmerdam|

there are clipping issues with both -order 3 and -tps methods of gdalwarp. (with latest GDAL SVN build; but it has been like this for years)
the attached images demonstrate.
-tps: for heavily "bent" images the edges of the image are slightly clipped off. In the example image this is most obvious in the bottom left, but is also there in the middle-right.
-order 3: regular part of image is fine, but a reflection of some sort makes the image much larger than it should be and leaves behind an artifact.
the third image is the input paper roll scan. GCPs were applied using gdal_translate.
The geotiff input image is available for download here: (5mb)
