RenderIntent

Values

Perceptual

Tries to preserve the visual relationship between colors in a way that is perceived as natural to the human eye, although the color values themselves may change. This is the same as the Image intent in Adobe PageMaker and Illustrator. This option is suitable for photographic, continuous tone images.

RelColorimetric

The same as absolute colorimetric, except that it compares the white point of the source color space to that of the destination color space and shifts all other colors accordingly, rather than comparing individual colors.

Saturation

Tries to create vivid color at the expense of accurate color. It scales the source gamut to the destination gamut, but preserves relative saturation instead of hue, so that when scaling to a smaller gamut, hues may shift. This is the same as the Graphics intent in Adobe PageMaker and Illustrator. This option is suitable for business graphics and charts, where the exact relationship between colors is not as important as having bright saturated colors.

AbsColorimetric

Tries to maintain color accuracy at the expense of preserving relationships between colors. It leaves colors that fall inside the destination gamut unchanged. When translating to a smaller gamut, two colors that are distinct in the source space may be mapped to the same color in the destination space. This type of rendering can be more accurate than if the colorAC_RelColorimetric, profile of the image contains correct white point (extreme highlight) information.

UseProfileIntent

Use the source profile's rendering intent.

UseGStateIntent

Use the source intent for the destination intent
