RGB image output

Description

../../../_images/rgbimage.jpg

Simulation results displayed as a RGB image

Output The RGB image output displays simulation results as a color image.

In order to display colors, the simulation results must contain standard X,Y,Z channels. Any white point may be chosen, and several output RGB color spaces may be used. For limited range formats (for 8-bit and 16-bit), highlights are clamped using a color correction algorithm acivated by the hcc parameter (Highlight Color Correction).

When saving an image file, the Depth and RGB space parameters directly controls the file encoding. The files generated are properly tagged with the corresponding ICC profiles and chromaticities.

When previewing an image inside Ocean, the Depth parameter has no effect. The RGB space parameter controls how the RGB picture is generated in memory, but if display color management is enabled, the image is converted again to the display color space as a second step.

Children Nodes

This node has a filter list. It may have a variable number of filter children. The name of each filter is user-defined and does not affect the result.
