Information processing 10 students may work to complete this module when they have finished all assignments in class. This is an independant module.
Please ensure that you have first created a folder in your info folder called Graphics_Your Last Name where you will place your completed assignments. Your assignments will be evaluated from this folder. DO NOT print any of these assignments unless otherwise instructed in the directions below.
You will be completing the majority of your assignments with a software program called the "G.I.M.P." or Graphics and Image Manipulation Software. It can be found by using your standard menu: start -> programs -> graphics -> Gimp 2
Graphics Module Assignments
For many of these activities you are asked to use your own photographs. These digital images can be uploaded to your network folder from home or you may sign out a digital camera from school to take photos for the assignments.

Assignment # 1 : Bitmap versus Vector Graphics
In this assignment you are to read about the difference between vector and bitmap graphics. Vector graphics describe images using lines and curves, called vectors that also include color and position information. When you edit a vector graphic, you modify the properties of the lines and curves that describe its shape. You can move, resize, reshape, and change the color of a vector graphic without changing the quality of its appearance. You can overlap objects so that they are partly hidden and alter transparency. Vector graphics are resolution independent, meaning they can be displayed on output devices of varying resolutions without losing any quality. Bitmap graphics describe images using dots, called pixels, arranged in a grid. Your computer screen itself consists of a large grid of pixels. In a bitmap graphic, each dot is assigned a color, and when viewed at the correct resolution, the dots go together like tiles in a mosaic to form the image. When you edit a bitmap graphic, you modify pixels, rather than lines and curves. These bitmap graphics are resolution dependent, because the data describing the image is fixed to a grid of a particular size. Enlarging a bitmap graphic can make the image's edges ragged, as pixels are redistributed within the grid. Displaying a bitmap graphic on an output device with a lower resolution than the image itself also degrades the image's quality.
Read the document vector_bitmap.doc located in the INFO folder on the network. This document explains the differences between the two formats.
Open the document: Graphics Assignment 1 located in the INFO folder on the network and save it in your graphics folder in your network folder. In this document you are to demonstrate the difference between vector and bitmap graphics by pasting one bitmap and one vector (possibly a wmf file or you can get vector images from clipart in ms-word) graphic into the document and then re-sizing each one by making it larger and showing the differences between the original and the re-sized side by side. You must ensure that after each original picture you type in the URL (universal resource locator or website address in the form http://www...) for the location of the image to avoid plagarism. Do this for any images in any future assignments that you use.
Assignment #2 - Rotate and Crop
Now you need to read and work through the GIMP tutorial: gimp_tutorial.pdf in the INFO folder.
In this assignment you are to find a graphic on the web that is allowed to be used for personal use (it cannot say that you are not allowed to copy this image - go to http://images.google.com to find pictures). Watch the video Crop and Rotate in the INFO folder to see how to rotate and crop an image in the Gimp software.
Note: you must go to edit-> copy to clipboard in the Gimp to make images available to your word document:
Create a new document called Assign 2 Rotate and Crop and insert the graphic you downloaded. Using the GIMP software, modify the graphic, once by cropping the original image , and second by rotating the image. Paste these resulting images in the word document so that you have the original and the two changed images, include a description of what you have done to each image.
Assignment #3 - Recoloring an Image
Visit http://gimp.net/tutorials/ and read the Red Eye Removal tutorial. Locate an image on the internet of a person or animal with red eye. Import the image into Gimp. Create a new document called Assign 3 Recoloring and insert a copy of the red eye image. Edit the image based on the instructions in the gimp tutorial so that the red eye no longer exists.
Choose an additional image (of anything) and recolor the image using the same technique. Include before and after copies of the image in the word document you created for this assignment.
Assignment #4 - Layers
Open the Layers_Tutorial.wps file from the INFO folder and read the instructions.
Create an image using layers. Ensure that you have created a rather detailed image (stickmen don't cut it!). Save the image as Assign 4 Layers.jpg in your folder.
Assignment #5 – Changing a Color Image to Black and White
There are several ways that GIMP can be used to remove color from a photo. Choose one of your own color photographs that you think would look nice as a black and white. Complete the tutorial at http://www.gimp.org/tutorials/Color2BW/ Create a word document called Assign 5 Black and White. Insert a copy of the original image into this document. Insert a copy of the image each time you change it in this tutorial. Include a brief description of what you have done to the image (the standard grayscale conversion, the desaturate operatrion, decompsong to RGB and using any one of the channels, decomposing to HSV and using the Value (V) channle, Decomposing to LAB and using the Lightness (L) channel and suing the Channel Mixer filter).
Assignment #6 -Selective Colorization
Selective colorization can be used to color only a portion of an image. I’m sure you’ve seen black and white photos that have a single item appear in color. In this tutorial you will take your own color photos, change them to black and white images and then use the selective colorization tutorial found here http://www.gimp.org/tutorials/Selective_Color/ to color part of the image. Use this effect to alter two of your own photos. Create a word document and save it as Assign 6 Selective Colorization. In this document include copies of the photos you are altering before and after you have completed the selective colorization. Choose your favorite of the two photos you have altered. Arrange with your teacher to have this printed in color.
Assignment #7 - Sketch Effects
For this assignment you will complete the tutorial on creating a sketch effect using GIMP. With the sketch effect you can take a regular color photo and alter the image so that it looks like it has been sketched. Complete this tutorial http://www.gimp.org/tutorials/Sketch_Effect/ using two of your own photos. Create a word document and save it as Assign 7 Sketch Effects. In this document include copies of the photos you are altering before and after you have completed the sketch effects. Choose your favorite of the two photos you have altered to print.

The “THIS” Riddle
I can be this, and you can be this. And yes, we can be this. He can’t be this, and she can’t be this. And too, they can’t be this. Dogs can’t be this but cats can. And a kitten can’t be this but a puppy can. Givers can’t be this but beggars can. And humility can’t be this but greed can. Not even peace can be this but fear can.
What is “THIS?”
