Output color profile.

icc= profile[, renderIntent[, blackpointComp]]


ICC color profile.


perceptual | relative | saturation | absolute


1 to enable, 0 to disable blackpoint compensation.

profile Specifies the output color space profile to which the rendered image should be converted if it is different from the working profile. 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).


profile May not include ‘,’ characters, even if HTTP-encoded.

renderIntent Allows overriding the default rendering intent.

blackpointComp Enables blackpoint compensation if the output profile supports this feature.


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.


May occur anywhere within the request. An error is returned if the image type is specified with fmt= does not match profile.

Both renderIntent and blackpointComp are ignored if not compatible with the specified ICC profile.

CMYK output device profiles are more likely to support different rendering intents.


If color management is enabled and icc= is not specified, the server delivers the image converted to the output profile ( attribute::IccProfile*) matching the image type specified with fmt=.

If not specified, renderIntent is inherited from attribute::IccRenderIntent, and blackpointComp is inherited from attribute::IccBlackPointCompensation.
