NOTE Regarding the Xtns menu: In Chapter 7, the author discusses the difference between FILTERS and EXTENSIONS found in the Xtns menu. The Xtns menu does not exist in GIMP any longer; the items have been moved to other menus.

1. What is a filter? It is an operation that can be applied to image, to give a wide variety of effects to the image.

2. What is the difference between a TOOL and a PLUGI-N? Plugins have to adjusted from within the dialog box, as with a tool you can click and adjust within the image itself.

3. What is the purpose of motion blur? It gives you the impression that the object in an image is moving or in motion.

4. Briefly describe the purpose of the following ENHANCE filters:

· Antialias: Helps to make jagged lines that are drawn to look smoother.

· Despeckle: Removes elements of “noise” or speck, and small lines caused by scratches or dust on a scanner.

· Destripe: Will remove vertical lines that are commonly left by some of the older scanners.

· NL Filter: Has the ability to try and fix all the above issues.

5. Briefly describe the purpose of the following DISTORT filters:

· Blinds: Makes image appear as if has been painted on venetian blinds, in which you can adjust the angle of the blinds.

· Curve Bend: Allows you to drag line in a dialog box to change the shape of an image into desired shape.

· Engrave: Creates a black and white “engraved” look, allowing you to adjust height and width of lines used.

· IWarp: Allows you to transform or warp an object in image making it appear smaller

6. Briefly describe the purpose of the following filters:

· Polar Coords: Can wrap an image around a point at the top or bottom center, or unwrap. It also wraps text in a circle.

· Ripple: Makes it appear as if you are seeing the image through water.

· Lens Flare: You can click or drag in preview to set a “flare” where you want in the image.

· Supernova: Like Lens Flare, but adds spiky rays to the flare.

· Drop Shadow: Represents a shadow that is tilted an angle to show perspective.

· Glass Tile: Makes it appear as if you are viewing image through a wall of glass bricks or tiles, each of which reflect light differently.

7. Describe various ways the EDGE filters are used in GIMP: There are six different edge-detection algorithms, each a little different. It gives a wild neon effect. The more colors the more “neon” effect will be and wrap, smear and black are options controlling the effect at the edges of the image.

8. What does the FILMSTRIP filter do? Allows you to see or view each layer of the image as a single image in a strip that looks like a 35 mm film.

9. List and describe 5 filters found in the ARTISTIC filters group:

a. Apply Canvas: Gives texture to an image making it appear as if it were on a canvas.

b. Cartoon Filter: Makes a photograph look like a hand-drawn and inked cartoon, by simplifying colors and adding black outlines near edges.

c. Predator: Gives it sort of a digital video game appearance from the 80’s, or scene of the movie “Predator.”

d. Weave: Makes image appear as if it had been woven into a basket.

e. Photocopy: Can make image look as though it had the properties of an image that had been copied using a poor quality copy machine.

10. What does the FRACTAL EXPLORER do? Allows you to create patterns in which you can adjust along with colors, shapes and sizes.

11. What does ALPHA TO LOGO do? Allows you to add or create a wide variety of effects to your text layer or any layer with transparency.

PART 2: GIMP PROJECTS:

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

1. WARP text:

1. Create a new GIMP image that is 600 X 400.

2. Use the paintbrush, gradients, etc. to create a lovely background.

3. Click on the text tool (letter A), and change the font, color (to coordinate with the background), change the size to fairly large (at least 200).

4. Type your first name in the text box (this creates a new layer with your name on it).

5. Warp the text: Make sure you are on the text layer. Now: FILTERSàDISTORTSàBEND CURVE. Drag the base line up/down to make it wavy. Click on PREVIEW ONCE to see the text distorted. When the text is distorted the way you want, click OK.

6. You can also add a Drop Shadow if you like: FILTERSàLIGHT AND SHADOWàDROP SHADOW.

7. Crop the image if needed, then save the image.

8. Insert your warped name image here:
