Move Tools  Move Selected Pixels  Move Selection outline

There are two Move Tools. One moves pixels in a layer or selection. The other moves the selection outline so it covers a different set of pixels.

Tip

It is important to understand the difference between the two Move Tools.

Move Selected Pixels
This tool moves the actual pixels under the current selection.
Move Selection outline
This tool moves the selection outline, leaving the pixels untouched.

Move Selected Pixels Move Selected Pixels
M once

This tool allows the user to move, rotate and scale the actual pixels that are in the active layer or under selection.  If no selection is active, the tool moves the entire active layer.

Click and drag to move the pixels to another location. As seen in the image below, once the pixels have been moved an area of transparency will be left in place of the moved pixels.  This is denoted by the grey and white checkerboard pattern.

Note

When pixels are moved on a layer, the checkerboard pattern that remains is an indication that the region is transparent.  The pattern is a visual cue and not part of the actual image.

Move Selection Move Selection
M twice

This tool allows the user to move, rotate, and scale the selection outline. This does not change any pixels on the active layer.  This is useful when refining the bounds of a selection.

Click and drag the selection outline to relocate it.

When this tool is active, a blue highlight will be added to the selection for greater clarity.

Control Nubs

When either Move Tool is active, several handles, known as Control Nubs, appear on the edges and corners of the selection:

Handles
Selection control nubs

Control Nubs are used to transform the shape and size of the selection or layer. Click and drag the nubs to relocate them.

Dragging one nub over the one diametrically opposite has the effect of flipping the selection or layer.

Move Cursor Move Cursor

Whenever the mouse pointer changes to a four-way arrow, the layer or active selection can be dragged.  The cursor changes when it is placed inside or well outside the selection or layer.

Click and drag with the Left Mouse button to move the selection or layer.

Move Icon Four Way Arrow icon

Whenever the four-way arrow icon is shown, the layer or active selection can be dragged to a new location.

Rotation Rotation icon

When the cursor is located in a corridor just outside the bounding rectangle, it changes to a double headed curved arrow.

Rotate Cursor
Rotate Cursor

The double headed arrow cursor is used to indicate a rotation is possible: Left click and drag the cursor to rotate the selection or layer about the center of rotation.

Tip

The Right Mouse button always accesses rotation - regardless of the location of the cursor.

The center of rotation of the selection or layer is shown when either Move Tool is active.  It looks like a circle with a cross in it and it determines where the selection will pivot when rotated.

Click and drag the rotation point to relocate it. The center of rotation can be moved outside the selection or even moved off-canvas.

Tip

While rotating, the angle of rotation is displayed in the Status Bar.
Constrain the angle of rotation to multiples of 15 degrees by holding down the Shift key while rotating.

Resize

Move the mouse over one of the Control Nubs and the cursor will change to a hand. Click and drag to relocate the Control Nubs.  This will resize the selection or layer.

Tip

When relocating a nub, hold down the Shift key to maintain the original aspect ratio (height vs. width).  This allows scaling without altering the shape of the selection or layer.

Resampling Modes

When rotating or resizing, there are three resampling modes available via the Tool Bar.

Rotation resampling modes
Resampling modes

The default mode is Bilinear. Bicubic resampling can produce higher quality results but it is more CPU-intensive. Nearest Neighbor produces a more pixelated result.
