o-exr: write openexr image files

this writes .exr files, 3 channel half float encoded. the output exr file will contain the chromaticities attribute. normally the pipeline will output linear bt2020 colour data, but you can select different primaries during export. the chromaticities attribute will contain coordinates for sRGB, bt2020, AdobeRGB, P3 (D65), or XYZ.

the module will also write non-linear data to the output files, though there is no standard attribute to be set in this case. there will be a warning on the console if you do so, make sure you know what you're doing.

parameters

• filename the name of the output file

connectors

• input half precision floating point rgba pixel data
