Layers Window Components
Think of layers in a multi-layered image as representing a stack of transparent sheets placed one on top of the other. Image elements on lower layers will be obscured by elements contained in layers higher in the stack if the element is in the corresponding area. For an in-depth discussion on this concept, please visit the Working with Layers section.
A new image is always created with a single layer named "Background". All images must have at least one layer.
The Active Layer
There is always one active layer. It can be identified by the highlighting in the
It is vitally important to understand that drawing operations only affect the active layer. The active layer is highlighted in the
It is easy to shift the active layer status from one layer to another. Simply click on any layer's name in the
Only one layer may have the active layer status at any time.
Assign any layer the active status by clicking on the layer in the
Layers can have their own blending mode and opacity settings. These are applied to every pixel in the layer.
Other layer options include whether a layer is currently visible or invisible (hidden).
Layer Window Icons
Add New Layer
This adds a new, completely transparent layer to the image immediately above the active layer. The new layer will be given a generic name "Layer X" by default. X denotes the layer number - hence it is always a unique identifier.
It is possible (and highly recommended) to change the default name to accurately reflect the contents of the layer (see Layer Properties below).
This deletes the active layer from the image. As all images must have at least one layer, the last remaining layer cannot be deleted.
This duplicates the active layer, including its contents and attributes. The new layer will be named uniquely following the pattern described above (Add New Layer).
Merge Layer Down
Takes the active layer and combines or merges it into the layer immediately below it in the
Move Layer Up
Moves the active layer one place higher in the layer order with each click.
Move Layer Down
Moves the active layer one position lower in the layer order with each click.
New to paint.net is the ability to change the order of the layers using drag-and-drop.
Click and "drag" any layer in the
