Create an application that makes a collage of images and graphics expressing something about you, your interests, or your life here at Furman. The collage image should be of reasonable size (e.g., 800 × 600 pixels or larger). It should combine images and graphics in a way that expresses your story. Specifications. 1.

Again, make sure that you submit all media sources needed in your work folder for testing your application properly. 4. As in the example, the main function (i.e., the function that is called in the Command Area should be named createCollage( ). NOTE: Since this is a standalone application, it needs no defined parameters. All of the pictures used are fixed or static, so they can be encoded into your source code. However, be sure to use relative referencing so that the program can be executed on any machine—not just yours. The setMediaPath( ) function can be used to handle the actual referencing. On the other hand, it is not recommended that you write it as one long, single sequence of code—even if the example does so. Instead, use topdown design for your organization and development. For example, you will likely be combining several original images. So, it makes sense to design individual functions to treat each one. These would be called by createCollage( ). Special effects or other tasks that might be used by more than one picture make good candidates for separate functions too. 5. Your program will be graded on several factors.

Create an application that makes a collage of images and graphics expressing something about you, your interests, or your life here at Furman. The collage image should be of reasonable size (e.g., 800 × 600 pixels or larger). It should combine images and graphics in a way that expresses your story. Specifications.
1. Name your source program file collage.py. It should combine a variety of elements from the repertoire of image processing and graphics skills that you have acquired so far. Here is a list of features to consider.
• photos, • ornamental graphic images, such as lines, ovals, boxes, etc., • graphic text, and • special effects, such as transparency, blending images, edge enhancement,
smoothing, sharpening, etc. 2. For an example of how to put together a compound image, see Program 77 (pages 170–1.) You can find additional information about JES picture functions in the JES IDE. Consult the Help Menu for section 06, “Understanding Pictures.” 3. The application should assemble the components and write them to a single (image) file in your work folder.

Special effects or other tasks that might be used by more than one picture make good candidates for separate functions too. 5. Your program will be graded on several factors.

a. correctness (i.e., program works without errors), b. overall results (content, interest, variety of effects, and originality), and c. program design features (use of top-‐‑down design, etc.).
6. In order to preserve your collage as a picture file, use the writePictureTo( ) function. Here is an example,
writePictureTo(canvas, “AllenCollage.jpg”)
where canvas is a picture object variable and the string “AllenCollage.jpg” names the file containing the picture. 7. Here are some samples of creations from previous class sections. Use your imagination and have some fun.
