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?

When one or more separate images are made to combine {on top of each other} into one image. 2. Why is transparency important when using layers?

It allows you to put part of one image on another. 3. Why would you use layers when creating images?

Layers allow you to do more effects with your image and allow you to work on certain parts of your image at a time. 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 WINDOWSRECENTLY CLOSED DOCKSLAYERS, 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

Change how transparent, opaque, or anything in-between a layer is. 2. Keep Transparent

It allows you to keep a lock on the transparency so the layer stays transparent. 3. Visibility Eye

This allows you to turn on or off the visibility of a layer. 4. Chain Link

When layers are linked together, you can move or transform any one of the layers altogether

5. Layer Mask

controls what part of a layer is visible, acts like a mask. 6. Raise and Lower Buttons

allows you to move layers up and down the layer stack. 7. Duplicate

allows you to create an exact copy of the layer you duplicate. 8. Delete

Allows you to delete an active layer. Describe the purpose of each of the following LAYERS context menu (menu appears when you rightclick on a layer) 1. Layer Boundary Size

Change size of the layer to which they can be bigger, smaller, or the same length as the whole image. 2. Layer to Image Size

Make the layer the same length as the whole image. 3. Add Alpha Channel (be sure to describe what ALPHA means)

Alpha is a fancy term that means transparency and this feature makes a layer capable of using transparency. It doesn't make anything transparent. 4. Alpha to Selection

Add Alpha Channel to selected area in the layer. 5. Merge or Flatten

Merge retains visible layers, while flatten merges all visible layers.
