Transforming changes a Layer appearance by modifying one or more of its physical characteristics. The free transform function in Mandala Painter include scaling, rotating and skewing.
Scale
Changes the size of the Layer
Rotate
Rotates the bounding box clockwise (positive angle) or counter-clockwise (negative angle)
Skew
Makes the image look like it is leaning. The top or bottom of the bounding box shifts to the left or right, OR the left or right side of the bounding box shifts up or down. The corner angles of the bounding box change but the opposite sides remain parallel.
When you transform a Layer using the Free Transform tool, you grab one of the handles of the Layer and basically stretching the picture.

Press CRTL-T

Drag the handles to scale and rotate
Press and hold SHIFT at scale if you want centered scale
Press and hold CTRL at scale if you want skew
