These U & V vectors determine either scale factors (for each U&V axis of a raster) and its rotation. If the vectors are not perpendicular, then the raster has a bias. The lengths of vectors determine the height & weight of one pixel. Therefore, the resulting image is the tetragon with points:

1. origin
2. origin + uVector * [X of the image resolution]
3. origin + uVector * [X of the image resolution] + vVector * [Y of the image resolution]
4. origin + vVector * [Y of the image resolution]
