This release features the ability to produce high-quality rotations at arbitrary angles. Look for the rotate theta toolbar button. Arbitrary rotations are useful for correcting for a horizon that is not quite horizontal, or in any case where rotations by 90 degrees will not cut it. A live preview of the rotation is available at interactive speeds. The rotation may be performed in a number of different modes and with a number of different filters (including the ability to rotate pixel art). The various modes include fill, which fills rotated-in empty-areas with a fill-colour, crop which crops the image where empty pixels are rotated in, and crop resize that does the crop but then resizes the image back to original dimensions.
Additionally there is now the ability to edit a specific pixel's colour and a big cleanup to the UI, especially for the canvas resize dialogs. For this dialog tabs are now used for the 3 canvas resize modes: anchor, remove borders, and aspect. Improvements and fixes include:
- Ability to use the cursor position as the anchor during canvas resize operations.
- Big cleanup to the resize dialogs. Use Ctrl-R for canvas resize, and Alt-R for image resize. R by itself is for rotate.
- A fine-tune drag-widget for rotation adjustments.
- Ability to rotate an image while zoomed-in.
- Ability to move the cursor around one pixel at a time using shift plus the arrow keys.
- A pixel colour editor.
- Border removal functionality with per-colour-channel matching (including alpha).
- Rework of all canvas resize dialogs into one dialog with 3 tabs.
- All fill-colour UIs allow picking the current cursor colour or the lower-left origin pixel colour.
- Crop mode rotations deal with the aspect ratio becoming inverted for rotations outside of 45 degrees.
- Cleanup of the FlipH and FlipV toolbar icons and addition of the Rotate Theta icon.
