GIMP: Chapter 3: Layers

PART 1: READ Chapter 3, pages 67-69, and 95-102 in the GIMP book, then:

1.            Answer all questions below, briefly but completely.

2.            Change the color of the answer to BLUE.

3.            Copy this information and paste in a new post in your DIGITAL GRAPHICS blog.

1.      What is a layer? One or more separate images laid on top of each other

2.      Why is transparency important when using layers?  It is important so that the background still shows through the image

3.      Why would you use layers when creating images? Layers help with moving objects in a picture and when editing the new layer could be deleted rather than starting from scratch.

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 Transparency controls

2.      Keep Transparent It is used to indicate transparency

3.      Visibility Eye It shows what layer is visible, it also controls what layer is visible

4.      Chain Link Links layers together

5.      Layer Mask Controls which layer is visible

6.      Raise and Lower Buttons Moves the current layer up or down on the list of layers

7.      Duplicate Creates a layer that is exactly the same as the active layer

8.      Delete Deletes the active layer

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

1.      Layer Boundary Size Lets the layers size alter

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

3.      Add Alpha Channel (be sure to describe what ALPHA means) It means transparency. It is used to make areas of an image transparent.

4.      Alpha to Selection It selects everything in the image that is not transparent

5.      Merge or Flatten Combines multiple layers into one.

PART 2: GIMP PROJECTS: Be sure to save these images in your GIMP folder before inserting them in this document.
