This command enables you to rotate items. As for Colorize, this command will give you the choice to operate on either selected frames or pixels. Prior to launch this command, you need to select the layer(s) and the frames or pixels that will be affected by the rotation. You may launch this command via:
|Tool bar||Menu bar||Shortcuts|
|Characters > Rotate||Shift + T|
Selecting the first tab will make the command operate on selected frames, while selecting the second tab will make it operate on selected pixels. Note that it may happen that the current selection (layer, frames or pixels) is incompatible with the command. E.g. this is the case if you selected more than one layer and that you are in pixel selection mode. If this happens, a red error message will appear at the bottom of the dialog, stating the issue.
The slider defines the rotation angle in degrees. The rotation sense is clockwise.
The smooth option will make a smooth render of the rotated area.
There are two commands that enables you to directly rotate the selected area by +90° or -90°. Unlike Rotate and most other editing commands, this command won't ask you directly if you want to operate on either selected frames or pixels. It will instead rely on the current mode: if the current selection mode is Frame selection, it will operate on selected frames. Otherwise it operates on selected pixels. Note that the current mode is displayed on the bottom right corner of the window.
Those commands are:
|Tool bar||Menu bar|
|Characters > Rotate by 90° clockwise|
|Characters > Rotate by 90° counter-clockwise|
The command will then run. Note that if you were in Frame selection, and no frames were selected, every frame will be flipped. Likewise, in Frame selection, and no layers were selected, every layer will be affected. In Pixel selection, if no pixels were selected, the whole canvas will be flipped. Note that still one layer must be selected to perform the command (in Pixel selection).
