Rotations--Again
Posted: October 22nd, 2020, 7:58 pm
Because a beginner to PWP might expect to find the ability to rotate an image by any amount in the Rotations and Reflections transformation, it might be worthwhile to add this capability there.
The ability of the Crop transformation to rotate an image is easily overlooked, but could be made more prominent by placing the Angle box under the heading Rotation which could be placed at the far left of the transformation window.
When an image is being rotated by Crop, new pixels not within the original image area but which are within the new image border are created and made black. Therefore, new pixels outside the original image area are "acceptable". However, the transformation only permits you to move inward the lines defining the crop. Moving them outward, which would need new pixels and which would create borders, is blocked. Why allow new pixels for an image when you rotate, but not otherwise? Why not let the lines defining the crop to move anywhere? Thus, you could crop and/or add borders from the same transformation. The color of the added pixels could be handled as it is in the Add Border transformation. Call it the Crop/Border transformation.
