  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? Anything that can operate on an existing image.
2.     What is the difference between a TOOL and a PLUGI-N? Plug-ins are downloaded from the internet. Tools can respond to clicking in the window.
3.     What is the purpose of motion blur? Blurs only in one direction giving the appearance of motion.
4.     Briefly describe the purpose of the following ENHANCE filters:
·       Antialias- Looks for jagged edges and makes them smoother
·       Despeckle- Removes small elements of noise from a picture
·       Destripe- Removes vertical lines from photos
·       NL Filter- Filters that work on the entire layer
5.     Briefly describe the purpose of the following  DISTORT filters:
·       Blinds- Makes the image appear as if it were painted on blinds
·       Curve Bend-Changes the shape of any layer
·       Engrave- Creates a black and white engraved look
·       IWarp- It has more deform modes
 
6.     Briefly describe the purpose of the following  filters:
·       Polar Coords- Wraps an image around a point at the top or bottom center
·       Ripple- Gives the image a look as if it were viewed through water
·       Lens Flare- Adds a flare to the photo, but must be drug into place
·       Supernova- Similar to a Lens Flare, but the flare has a sharp area
·       Drop Shadow- A shadow created around an object
·       Glass Tile- An effect that appears to have a layer of glass bricks over an image
7.     Describe various ways the EDGE filters are used in GIMP: They detect the edges of an object and adds different lighting effects to them
8.     What does the FILMSTRIP filter do? Combines layers of photos into a filmstrip 
9.     List and describe 5 filters found in the ARTISTIC filters group:
a. Apply canvas
b. Cartoon
c. Photocopy
d. Soft glow
e. Van Gogh
 
10.  What does the FRACTAL EXPLORER do? It makes fractal patterns
 
11.  What does ALPHA TO LOGO do? Creates interesting effects on text layers
 

 

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:
