Abstract
Disclosed are various embodiments for performing color blending of document objects using GPU hardware of a computer. A computer obtains a document specifying a first object and a second object presented in the document, where a portion of the second object overlaps the first object. The computer renders, on a display device, a presentation of the document, where the rendered presentation including the first object of the document. In response to determining that the document specifies blending the second object with the first object in the overlapping portion, configuring dual-source color circuitry of a graphics processing unit (GPU) of the computer to compute, via a dual-source color blending operation, a result color for the blended first and second objects. The computer renders, on the display device, the second object of the document using the result color for the overlapping portion.
