bitmap-filter

Filters for 24 bit uncompressed bitmap images. Available filters are:

• Grayscale - Converts the image into a single sample containing only intensity information.

• Reflect - Converts the image into its mirror image.

• Blur - Blurs the image.

• Edge - Highlights the edges in the image. It uses basic sobel operator to detect the edges.
