I've been working with the software to design patterns... The software can import pictures, graphic elements, clip art, and a lot of other forms of digital artwork. It converts those images into a grayscale format. It does this by taking the pixels and changing them to different levels of white and dark. These differing shades of light and dark are then converted to depth. the darker the pixel, the deeper the depth.
While trying my hand at scanning images and converting them to patterns, I found that I needed to do some manipulations to the scanned images. This especially true of clip art. Clip art is strictly black and white and so the carving would turn out to be very exaggerated. What I need to do is find a way to adjust the images and change or rather swap colors.
