Rotation and Translation issues

Feb 4 2008 5:40 PM

Hi

Here is my project: I am drawing a table and a set of chairs on the screen, All the dimensions of the table and chairs are in inches. The first thing that I do is resale the 600x600 matrix to work in inches and have 0,0 be in the center of the screen. I can easily draw the table and the chairs. The table is a rounded rectangle that goes exactly in the center and I draw each of the chairs as a path. I am able to correctly position the chairs using a sequence of translations and rotations.  This all works wonderfully and I can change the dimension of the table, in inches, and the whole graph will resize and rescale for me.

The problem: I would like to use an image for the chair instead of drawing it. I have spent two days trying to get rotations, translations and whatever to put these chair images where the chair drawings were with no luck.  I must be missing something.

I have been through Mahesh’s book a half a dozen times already but his examples are not enough for me to extend them to this problem.

Could anyone give me a design approach or a good idea that I could try to solve this problem.

Thanks
