exr2aces [options] infile outfile

Description

Read an OpenEXR file from infile and save the contents in ACES image file outfile.

The ACES image file format is a subset of the OpenEXR file format. ACES image files are restricted as follows:

• Images are stored as scanlines; tiles are not allowed.

• Images contain three color channels, either R, G, B (red, green, blue) or Y, RY, BY (luminance, sub-sampled chroma)

• Images may optionally contain an alpha channel.

• Only three compression types are allowed:

  • NO_COMPRESSION (file is not compressed)

  • PIZ_COMPRESSION (lossless)

  • B44A_COMPRESSION (lossy)

• The “chromaticities” header attribute must specify the ACES RGB primaries and white point.
