1.      What is a layer? It’s a separate image

2.      Why is transparency important when using layers? Because it lets you see what is under.

3.      Why would you use layers when creating images? Because Layers let you go back and edit and revise without disturbing other layers.

LAYERS DIALOG BOX: The following refers to information on pages 95-102 in the book. Open GIMP and look at the LAYERS DIALOG BOX while you read these pages. NOTE: If the LAYERS box is not open, open it by WINDOWSàRECENTLY CLOSED DOCKSàLAYERS, CHANELS, PATHS. The LAYERS box is the tab with what looks like several sheets of white paper (see Figure 3-31 on page 96).

Describe the purpose of each of the following LAYERS properties in the LAYERS dialog box.

1.      Opacity creates  different useful effects using transparency  levels.

2.      Keep Transparent (Lock) does not let you draw where the current layer is transparent.

3.      Visibility Eye Clicking on the eye toggles the layer’s visibility.

4.      Chain Link means that the layers are linked together. Chain Link can be turned off to see how the rest of layers look without that layer.

5.      Layer Mask  Controls which part of the layer is visible

6.      Raise and Lower Buttons moves the current layer up or down in the layer stack.

7.      Duplicate Creates a new a layer that is an exact copy of the active layer.

8.      Delete throws away any item unwanted.

Describe the purpose of each of the following LAYERS context menu (menu appears when you right-click on a layer)

1.      Layer Boundary Size let you change a layer size

2.      Layer to Image Size it makes the layer as large as the whole image.

3.      Add Alpha Channel (be sure to describe what ALPHA means) makes the layer capable of using transparency. ALPHA means Transparency.
