Hi Mirek,

Please find attached a small extension to plugin/tif/tifupp.cpp. This one supports geotiepoints without scale by mapping a transformation using Xform2D::Map().

Additionally, handling the not so common fill ordering of those sample geotiffs gains help by adding field 'orientation' to page info. (This way I can externally flip the image after reading it in with plugin/tif.) I'm not sure if it should be internally flipped in plugin/tif and just returned in a sensible orientation (i.e. orientation = 1) as any other image. What's your opinion on this?

The horizontal flip crash in tif_getimage remains unsolved.

Best regards,

Tom

EDIT: Removed tifupp.cpp in favor of new version below...
