suggestion for warp transformation : zooming outside of input image
Posted: October 26th, 2023, 4:35 pm
Scenario :
Allow zooming 1:1 on out-of-image endpoints.
- Open an input image containing a rectangular area with one of the corners missing ( out of image ).
For example, a picture of a framed painting on a wall, which the photographer did not completely capture in the photo. - Use the warp transformation to straighten the image. One of the 4 warp reference points is out of the input image.
- Perform coarse alignment of the 4 points using a zoomed-out magnification.
- Set zooming of the input image to 100% ( 1:1 ).
- Visit each of the 4 reference points for precise manual alignment using the keyboard shortcuts 1-2-3-4.
- The endpoint which is out of the image area cannot be displayed using its keyboard shortcut.
Allow zooming 1:1 on out-of-image endpoints.
