Follow-up Comment #5, bug #61760 (project octave):
This is an update with the following improvements:
* The coding style is now more consistent.
* The type cast of the input image is now optimized. For 8 and 16 bit types
single precision is enough. A performance test is commented out at the
bottom.
* The implementation had issues when the resulting image gave a single row,
single column or single pixel. There are now new tests for that and the issue
is fixed of course.
Note: Lanczos2 and Lanczos3 are still not fixed. So, consider this still as
work in progress.
BTW: I attached the full file again. Are you OK with this or should I rather
attach a diff to the current tip? I did not reattach interp_method.m, since it
is unchanged from comment #4.
(file #52695)
