NAME¶
Warp - warp (transform) input dataset
SYNOPSIS¶
astwarp [OPTION...] ASTRdata
DESCRIPTION¶
Warp is part of GNU Astronomy Utilities 0.14. Warp 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. In particular the second contains a very comprehensive explanation of Warp's invocation: expected input(s), output(s), and a full description of all the options.
- All options and their values:
- $ astwarp -P
- Inputs/Outputs and options:
- $ info astwarp
- Full section in manual/book:
- $ info Warp
- Full Gnuastro manual/book:
- $ 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
