Output Color Profile.

icc= *object*[, *renderIntent*[, *blackpointComp*[, *dither*]]

object
ICC color profile.
renderIntent
perceptual|relative|saturation|absolute.
blackpointComp
1 to enable, 0 to disable blackpoint compensation.
dither
1 to enable, 0 to disable dithering.

The value object specifies the output color space profile to which the image should be converted if it is different from the working profile. The value profile must be either a valid icc::Name defined in the ICC profile map of an image catalog or default catalog, or a relative path to a profile file (typically with .icc or .icm suffix). See object for additional information.

NOTE
The value object may not include ‘,’ characters, even if HTTP-encoded.

The value renderIntent allows overriding the default rendering intent.

The value blackpointComp enables blackpoint compensation if the output profile supports this feature.

NOTE
Not all color conversions support all renderIntent and blackpointComp choices. Typically, these settings are honored only when the ICC output profile characterizes an output device such as a printer or monitor. Also, some ICC output profiles do not support all renderIntent choices.

Note

The modifier dither enables dithering (actually error diffusion), which may avoid or reduce color banding artifacts.
