Using this tool, you can transform the active texture by scaling, rotating, or shearing it and so on.
The starting point for this tool can be:
When this tool is activated, a frame will appear around your selection (or layer content). This frame consists of four corners and four sides, each of which can be grabbed and moved with the mouse - the results of which will vary, depending on the option selected.
We recommend the Auto option. Depending on which part of the frame your cursor nears, it will display information regarding the type of transformation that is possible. You can click inside of the frame, on its corners or sides, or even outside of the frame to move, rotate or scale (grabbing corner points will scale the frame proportionally) its contents.
The other modes can be used if you are zoomed very closely into the texture and the frame is no longer visible. In this case you can use the Rotate option to rotate the frame, which would not be possible in Auto mode.
Note that only the frame is transformed in real-time — transform the frame as you intend the active layer to be transformed, then click on the Apply button (or double-click inside the frame) to transform the active layer.
Keep in mind that Transform Bitmap affects the active layer only. If you attempt to activate another layer (by clicking it) while the frame is active, a warning dialog will open. Click Yes to apply the transformation or Cancel to abort it.
