Plot lines (and text) directly into a bitmap, including filled polygons.

File Information

"Plot to Bitmap" allows the user to directly plot lines, text and filled polygons into an image, thus without taking a screen-shot (getframe).

This function is also useful if you want to convert a few coordinates describing a region contour into a bitmap of the region.


This file inspired Contest Clock.

Very good. This made it possible for me to create synthetic images to test an image processing algorithm.
Doesn't fill polygons right to the edge of the image. X and Y seem to be flipped in the bitmapplot function.

Replace for-loop by arrayfun. Allow multiple marker-colors.
