GIMP: Chapter 3: Layers
PART 1: READ Chapter 3, pages 67-69, and 95-102 in the GIMP book, then:
- Answer all questions below, briefly but completely.
- Change the color of the answer to Red.
- Copy this information and paste in a new post in your DIGITAL GRAPHICS blog.
1. What is a layer? Separate images.
|
2. Why is transparency important when using layers? It lets you put part of one image on top of another.
|
3. Why would you use layers when creating images? You have more control – you can edit and revise as much as you want; size, location, etc.
|
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: Controlling transparency of an image, float text.
|
2. Keep Transparent: AKA “lock”; Inhibits you from drawing where the current layer is transparent.
|
3. Visibility Eye: Lets you know which layers are visible.
|
4. Chain Link: Means layers are linked and moving/transforming any of the layers affects those linked.
|
5. Layer Mask: Controls which part of the layer is visible. If white, visible, If black, transparent.
|
6. Raise and Lower Buttons: Moves layers in the stack. Used if you want to put one layer specifically on another.
|
7. Duplicate: Creates an exact copy of the active layer and puts it in a new layer.
|
8. Delete: Deletes an 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 you change a layer size, useful with text.
|
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): Alpha means transparency. It makes the layer capable of using transparency.
|
4. Alpha to Selection: Selects everything in the layer that is transparent.
|
5. Merge or Flatten: Option to merge multiple layers into one.
|
