Paint Modes - A


AddNoise

Secondary : No

Uses colour : No

Options : Noise type and Noise Amount (Percentage)

Description :

Adds 'noise' to an image (to simulate bad TV reception or a grainy image)

There are several types of noise that can be applied:

Random Noise:

The image is mixed with totally random pixels.

Max Luma Limited:

The image is mixed with random grey pixels, but the resultant pixels are never brighter than the original.

Min Luma Limited:

The image is mixed with random grey pixels, but the resultant pixels are never darker than the original.

Hue Fixed Noise:

The image is mixed with random grey pixels.

Blue Noise:

The image is mixed with random blue pixels (blue is the darkest colour component, and as such Blue Noise can be much more subtle than other noises).

Nice 'stone' effects can be created by using AddNoise followed by Blur.

AlterHue

Secondary : No

Uses colour : Yes

Options : None

Description :

Change hue to current colour. A powerful type of Tint operation that changes the hue (or colour) of an image without changing the brightness or saturation (so coloured pixels change but grey pixels remain grey). Compare with Tint.

Antique

Secondary : No

Uses colour : No

Options : None

Description :

Tints a picture with a sepia tint to simulate an old faded Photograph. Best used in combination with AddNoise and Blur.
