Abstract

Methods, systems, and apparatus, including medium-encoded computer program products, can perform rendering and un-rendering using profile replacement. A computer implemented method includes obtaining source image data associated with a source input-referred color space, transforming the source image data to intermediate image data associated with an intermediate input-referred color profile, applying a rendering operation to the intermediate image data by associating the intermediate image data with an intermediate output-referred color profile, and transforming the intermediate image data to destination image data associated with a destination output-referred color space using the intermediate output-referred color profile. The method further includes making available for output the destination image data.

6. The method of claim 1, wherein the intermediate input-referred color profile and the intermediate output-referred color profile are International Color Consortium profiles.

7. A computer implemented method comprising:

obtaining source image data associated with a source output-referred color space;

transforming, by one or more data processing apparatus, the source image data to intermediate image data associated with an intermediate output-referred color profile;

applying, by the one or more data processing apparatus, an un-rendering operation to the intermediate image data by associating the intermediate image data with an intermediate input-referred color profile;

transforming, by the one or more data processing apparatus, the intermediate image data to destination image data associated with a destination input-referred color space using the intermediate input-referred color profile; and
