Overflow Behavior How the effect remaps values that fall outside the grayscale range of 0-255.

• Clip Values above 255 are mapped to 255. Values below 0 are mapped to 0.

• Wrap Values above 255 and below 0 are wrapped back around into the 0-255 range. For example, a value of 258

wraps around to 2, a value of 256 wraps around to 0, and a value of -3 wraps around to 253.

• Scale The maximum and minimum values are remapped to 255 and 0, and intermediate values are stretched or

compressed to fit within this range.

Stretch Second Source To Fit Scales the second layer to match the size (width and height) of the current layer. If this

option is deselected, the second layer is placed at the current size of its source, aligned with the upper left corner of the

source layer.

Blend With Original The transparency of the effect. The result of the effect is blended with the original image, with the

effect result composited on top. The higher you set this value, the less the effect affects the layer. For example, if you

set this value to 100%, the effect has no visible result on the layer; if you set this value to 0%, the original image doesn’t

show through.

Invert effect

The Invert effect inverts the color information of an image.

This effect works with 8-bpc, 16-bpc, and 32-bpc color.

Channel Which channel or channels to invert. Each group of items operates in a particular color space, inverting either

the entire image in that color space or only a single channel.

• RGB/Red/Green/Blue RGB inverts all three of the additive color channels. Red, Green, and Blue each invert an

individual color channel.

• HLS/Hue/Lightness/Saturation HLS inverts all three of the calculated color channels. Hue, Lightness, and

Saturation each invert an individual color channel.

• YIQ/Luminance/In Phase Chrominance/Quadrature Chrominance YIQ inverts all three NTSC luminance and

chrominance channels. Y (luminance), I (in-phase chrominance), and Q (quadrature chrominance) each invert an

individual channel.

• Alpha Inverts the alpha channel of the image. The alpha channel isn’t a color channel; it specifies transparency.

Blend With Original The transparency of the effect. The result of the effect is blended with the original image, with the

effect result composited on top. The higher you set this value, the less the effect affects the layer. For example, if you

set this value to 100%, the effect has no visible result on the layer; if you set this value to 0%, the original image doesn’t

show through.

Minimax effect

The Minimax effect assigns each channel of a pixel the minimum or maximum value for that channel found within a

specified radius.
