Posted by Kazper at 11:15am Jan 2 '09Drawing frames aren't necessarily squares. If you have a certain image you want to capture then it will dictate the drawing frame which is likely to be a horizontal or vertical rectangle.
You have to determine the shape of the drawing frame first, whether it is horizontal or vertical or square before you can draw it to whatever scale will fit your paper.
You could determine the highest and lowest points and determine the approxiamate angle between them. If the furthest right and left points don't exceed or fall short of the top and bottom points and if the angle between the top and bottom points is also a 45 degree angle then the drawing frame is a square.
If the right and left points exceed the top and bottom points then the drawing frame is a horizontal rectangle, the width of which is determined by the right and left points.
If the right and left points fall short of the top and bottom points then the frame is a vertical rectangle, the width of which is determined by the top and bottom points.
If the right point exceeds but the left point doesn't then we may have a vertical, square or horizontal rectangle, the width of which is determined by either the top or bottom point/s and the right point. The same but reversed if the left point exceeds but the right point doesn't.
The paper you're using already gives you the maximum dimensions your drawing frame can be but you may not want the whole page to be used so a square or rectangle could be drawn with the maximum width and height that you want and in which the actual drawing frame will be constructed.
We just need to determine whether the drawing frame is horizontal, vertical or square. The scale frame gives us the length of the longest dimension of our drawing frame. With a horizontal drawing frame that means the width. With a vertical drawing frame that means the height. With an approxiamate ratio of the shorter dimension of our drawing frame divide the longer dimension of our drawing frame we can determine the length of our shorter dimension (the actual physical length of the dimension of the scale frame which corresponds to the longest dimension of our drawing frame multipied by that approxiamate ratio equals the actual physical length of the shorter dimension of our drawing frame). The shorter dimension is the vertical for a horizontal drawing frame and the horizontal for a vertical drawing frame.
Margin frame, border frame, scale frame and drawing frame. The drawing frame is centered in the scale frame and the scale frame is centered in the border frame and the border frame is centered in the margin frame.
The longest dimension of the drawing frame equals the corresponding dimension of the scale frame in length.
The margin frame is independent from the border frame and is determined by the desired margin. The border frame is determined by the desired space around the scale frame and so the centered drawing frame which will contain the image. It must not exceed the margin frame though both could merge and the margin frame could also function as the border frame.

Border frame (not always determined but when it is should probably be drawn... or else why was it determined...)
