PART 1: READ Chapter 2 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.

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? Filter is a general term for anything that can operate on an existing image.

2.      What is the difference between a TOOL and a PLUG-IN? Tools can use dialog boxes or by dragging it on the screen to change the image but a plug-in you have to use the dialog box.

3.      What is the purpose of motion blur? It is to blur in one direction depending on the angel you pick so that it looks like the object is moving.

4.      Briefly describe the purpose of the following ENHANCE filters: ·        Antialias Looks for jagged edges and tries to make them looker smoother. ·        Despeckle is used to remove small elements from the image, particularly specks or small lines. ·        Destripe removes vertical lines that are left by some older scanners. ·        NL Filter tries to do everything: it’s a combination of smoothing, despeckle, and sharpen in one filter.

5.      Briefly describe the purpose of the following  DISTORT filters: ·        Blinds Make it look like your image is painted on venetian blinds and you are changing the angles of those blinds. ·        Curve Bend Is useful for changing the shape of any layer. ·        Engrave Creates the black-and-white “engraved” look that you sometimes see in old illustrations. ·        IWarp Stretches the image like it was on a rubber sheet.

6.      Briefly describe the purpose of the following  filters: ·        Polar Coords filter wraps an image around a point around a point at the top or bottom center. ·        Ripple filter makes an image look as though it’s being viewed through water waves. ·        Lens Flare makes the picture look like it has a glare on it. ·        Supernova makes a flare with spiky rays and you can change the color of the flare. ·        Drop Shadow a show behind an image. ·        Glass Tile makes the image look like it is being viewed through a wall with many glass bricks.

7.      Describe various ways the EDGE filters are used in GIMP: The edge filters are use to make the edges the way you want them to look. They can make jagged edges or soft edges.

8.      What does the FILMSTRIP filter do? It takes all the images you have open in different GIMP windows and combines them in a filmstrip.

9.      List and describe 5 filters found in the ARTISTIC filters group: a. Cartoon- makes it look like the image is hand drawn by adding black outlines near the edges. b. Softglow- gives a “bathed in light” impression, as though the image was hazy and a bit overexposed. c. Cubism- makes the image look like it is made up of a lot of little cubes. d. placement- controls how the brush strokes will be grouped on the page. e. orientation- adjusts the angle of asymmetrical brushes.

10.  What does the FRACTAL EXPLORER do? It makes a lighting strike design.

11.  What does ALPHA TO LOGO do? Scripts create interesting effects from a text layer.

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:
