Victor, it's pretty simple. There are a variety of drawing methods to draw lines and more complex shapes. Take a look at the delphi help. I searched the index for "Line" and found this:

I have never done any graphic type programming and could use a little help getting started. I wish to write a small app for a friend that is not math inclined. She is an artist and has a need to cut mattes for her pictures. She owns a decent matte cutter. The problem is like this: She wants to cut a rectangular matte whose outside dimensions, say are 14 inches by 10 inches. Her painting is 12 inches by 8 inches. She must set her matte cutter to the width of the difference between the, say, 14 inches and 12 inches = 2 inches divided by 2 = 1 inches and the difference between 10 inches and 8 inches = 2 inches divided by 2 = 1 inch. This would give a centered cut out for the painting and have 1 inch borders on all sides. This is simple enough to do in your head, but often she does not have nice round numbers to work with and must deal in fractions (1/8ths or 1/16ths) which is difficult for her to do. I thought I could write her a short app which allowed her to enter the data and then display the proper measurements by drawing a rectangle for the frame and another one for the cut-out. Then she would have the correct numbers for setting her matte cutter and be able to visualize what it would all look like. I am not sure how to go about drawing the nested rectangles. I do not know how to draw anything on a form. Any enlightenment will be appreciated.
