Layers
• In GIMP terminology, each individual transparency is called a layer.
• It provides a variety of effects that change the appearance of the image.
• A new image in Gimp has a single layer. We can add a number of additional layers to add different elements in an image.
• Adding a new layer:
→ Layer menu → select new layer.
→ Enter the information such as name, height, width and transparency for a new layer.
• Renaming a layer:
→ Highlight the layer, right click it
→ Select edit layer attributes, then type in a new name.
• Deleting a layer:
→ Select the layer and press the bin like looking button at the bottom of layers tab.
• Merging a layer:
→ Open both the images as layers.
→ Right-click the layer and select merge down or merge visible option available in the drop-down menu.
(The Merge down option merges the selected layer with the layer right below it, whereas the Merge visible option merges all the visible layers.)
→ Resultant image, after merging the two layers.
• Scaling a layer:
→ In the image menubar through Layer → Scale Layer.
→ It resizes the layer and its contents.
• Duplicating a layer:
→ Click image menu→ Layer → Duplicate Layer, or
→  From the local pop-up menu that you get by right-clicking on the Layer Dialog.

Masking
• The Mask is GIMP’s way of showing the full structure of the selection.
• It provides the ability to interact with the selection in new, and substantially ways.
• How to do masking:
→ Click the small outlined button at the lower left of the image window to toggle Quickmask on and off. or Select → Toggle Quickmask, or Shift + Q, to toggle between Quickmask and marching ants mode.
→ By default the mask is shown in red, but you can change this if another mask colour is more convenient.

→ Go to the channels tab, select “quickmask” channel, right-click to open the drop-down menu.
→ Select Edit channel attributes…and change the colour.
