Section 3: Color Management


AssignICCProfile is used to assign a ICC profile to an image.

Current Profile: It shows the description of the ICC profile assigned to the image selected on the view selection combo box (M63M51_RGB in the example above), or the default RGB ICC profile (as selected in the Color Management Setup dialog) if no particular view is selected. You cannot change the profile description.

New Profile lets you assign an ICC profile to the target image.

Assign the default profile: It assigns the default ICC profile to target image.

Leave the image untagged: It does not add a ICC profile to the image. In this case, the default profile will be used to manage its color.

Assign profile: here is where you can assign a different ICC profile to the image.


This process allows converting an image from its current ICC profile to the color space defined by a different ICC profile. One instance when this process can be useful is for example when preparing an image for being published on the Web.

Source Profile: The image whose ICC profile we wish to change.

Target Profile: The new profile we want to assign to the source image.

Convert to the specified profile: Select this option if you want to assign to your source image one of the several available ICC profiles.

Convert to the default profile: Depending on whether your source image is RGB or grayscale, selecting this option will assign the default profile to the image.

Rendering Intent: When the gamut of source color space exceeds that of the destination, saturated colors are liable to become clipped (inaccurately represented). The color management module can deal with this problem in several ways:

Floating point transform: ICC transformations often benefit from being done in floating point. If our source image is not in floating point format, it will be transformed to 32-bit floating point.
