NAME¶
ImageWarp - warp (transform) input image
SYNOPSIS¶
astimgwarp [OPTION...] [matrix.txt] ASTRdata ...
DESCRIPTION¶
ImageWarp is part of GNU Astronomy Utilities 0.2.33-8a3b. ImageWarp will warp/transform the input image using an input coordinate matrix. Currently it accepts any general projective mapping (which includes affine mappings as a subset).
For more information, please run any of the following commands. They will respectively show you the `Invoking ImageWarp' subsection, the complete `ImageWarp' section, or the full GNU Astronomy Utilities manual. In particular the first contains a very complete explanation of each option.
- info astimgwarp
- info ImageWarp
- info gnuastro
If you couldn't find your answer in the manual, you can get direct help from experienced Gnuastro users and developers. For more information, please run:
- info help-gnuastro
