6.2 Warping user interface
To apply warping to an image, select “Warp” from the left hand toolbar. The window in Figure
6-1 will appear.
Figure 6-1. Warping algorithm setup
Algorithms can be added or removed. If the perspective transform is added first, Mesh Warp
Transform can be used in addition. If Mesh Warp Transform or Mesh Warp Bezier is added
first, a combination of algorithms is not allowed.
In this window, grid size is also configured. For the control points of an algorithm to be
visible, the grid size must be at least 1x1.
Increasing grid size during calibration is very convenient. This enable for rough calibration
with few control points, and fine tuning with increased grid size as needed.
Decreasing grid size during calibration is not recommended as you may lose fine tuning data
you have already added to the grid.
