This menu contains commands that affect all layers in the current image. This contrasts with the Menu commands, which only affect the active layer.
Crop to Selection
This menu item is only available if a selection is active. Clicking this menu item will cause the current image to be cropped and replaced by the area that was selected.
If the selection is not rectangular or square, the bounding rectangle minimally surrounding the selection will be used. Pixels outside the selection will be made transparent.
Example - Crop to Selection
Here a selection has been made around the car using the
Following the image has been resized to minimally encompass the previously selected area. Pixels lying outside the selection have the checkerboard pattern which denotes transparency.
The checkerboard pattern is used to indicate areas of the image that are transparent. This pattern not a part of the image and will not be seen outside of paint.net's editing environment.
This command changes the size of the image. The image can be either enlarged or reduced to the size specified. Clicking the menu item opens the following dialog.
"Resampling" is the process of computing how new pixels appear based on the existing pixels. There are four types of resampling that can be chosen. Some algorithms produce better looking results, but take longer to complete.
It is recommended that the default option, "Best Quality," is used unless there is a specific need for, and understanding of, the
Two resize modes are By percentage and By absolute size. These offer the option of changing the size by a percentage or specifying a new Height and/or Width.
If the "Maintain aspect ratio" option is checked, typing a new Width value will maintain a proportional Height value, and vice versa.
The print size is calculated based on the resolution (DPI).
Pixel Size / DPI = Print Size
This formula can be rewritten Print Size x DPI = Pixel Size
For example if an image is specified to be printed at two inches wide, and the resolution is set to 96 pixels/inch, then the image will be resized to a width of 96 x 2 or 192 pixels. This is how many pixels will be required to make the image two inches wide when printed at a density of 96 dots-per-inch.
Example - Resizing an Image
Depending on the type of image that is being resized, using the effect can enhance details softened by the command.
This command enlarges or shrinks the canvas without affecting the size of the image on it.
works similarly to the dialog, but adds an
If the canvas is enlarged, the new area will be filled with pixels the same color as the

Flip Horizontal, and Flip Vertical
These menu items allow the image to be flipped horizontally or vertically. Remember - ALL layers will undergo this transformation.
Example - Flipping an Image
Rotate 90 ° Clockwise
Rotate 90 ° Counter-Clockwise
Rotate 180 °
The next three menu items rotate the image by 90° (in either clockwise or counter-clockwise directions) or by 180 degrees.
Example - Rotation
To rotate an image by angles other than 90° or 180° see the Move Tool section.
This action takes an image with multiple layers and combines them into a single layer.
The action becomes available only when an image has more than one layer.
