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 BLUE.
- Copy this information and paste
in a new post in your DIGITAL GRAPHICS blog.
1.
What
is a layer? Layers are combining one or more separate
images lay on top of each other.
|
2.
Why
is transparency important when using layers?
If
a layer is not transparent, then the bottom image will not be seen.
|
3.
Why
would you use layers when creating images? If a mistake is made, instead of
deleting the whole project, only a layer can be deleted.
|
LAYERS
DIALOG BOX: The following refers to information 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:
Shows color—either a solid color or see through
(transparent)
|
2.
Keep
Transparent: This will lock the current
transparent layer and will not allow anything to be drawn on the transparent
area.
|
3.
Visibility
Eye: When the “eyeball” is showing,
then that layer is visible, when it is off, layer is invisible.
|
4.
Chain
Link: When having several layers, the “chain
link” will let you know that all layers are linked together.
|
5.
Layer
Mask: Controls which part of the layer
is visible. Another way of
representing transparency.
|
6.
Raise
and Lower Buttons: Moves the
layer up or down in the layer stack.
|
7.
Duplicate: A new layer that is an exact copy of the active layer
or of any layer you drag onto the button.
|
8.
Delete: Deletes the active layer. You can also drag the layer to the button
to delete it.
|
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 the layer’s
size, either bigger or smaller.
|
2.
Layer
to Image Size: Makes the layer the size
of the whole image.
|
3.
Add
Alpha Channel (be sure to describe what ALPHA means): Alpha is another word for transparency. It makes the layer capable of using
transparency.
|
4.
Alpha
to Selection: Selects everything in the current
layer that is not transparent.
|
5.
Merge
or Flatten: Combines two layers and melts into
one.
|
PART 2: GIMP PROJECTS:
Be sure to save these images in your GIMP folder before
inserting them in this document.

2. Look through the menus on the left
to see the supplemental information provided for you about the book.
3. Click on the PHOTOS FROM THE BOOK
link, and scroll down to see the images for Chapter 3.
4. Click on the Goblin Valley image, then right-click and select SAVE IMAGE AS.
Save the image in your GIMP folder.
5. Click on the Mars from the Hubble image, then right-click and select SAVE
IMAGE AS. Save the image in your GIMP folder.
6. Click on the yellow airplane image (the fifth image in the image list), then
right-click and select SAVE IMAGE AS. Save the image in your GIMP folder.
7. Create a new image by following the
instructions on pages 69 (from
“Using Layers to Add Text”) through
95. Through this exercise, you will learn to add text to an image, change
text colors, add a drop shadow to text, link layers together, and add images
to other images.
8. After you have completed the image
displayed on page 94, add the yellow airplane to the image in an
appropriate place.
9.
When
the image is complete, save as JPG file and insert here:

This is from Chapter 3--Introduction to Layers. I used the image from gimpbook.com, added a text layer and used the rotate tool to rotate the text box. I inserted Mars and scaled down the image to use as a nose on the front of the rock to give it some character...like a dog (poodle). Then I copied and pasted the Bi-plane in the background.
