Given type of an extra channel.

bits_per_sample

int bits_per_sample

Total bits per sample for this channel.

exponent_bits_per_sample

int exponent_bits_per_sample

Floating point exponent bits per channel, or 0 if they are unsigned integer.

dim_shift

int dim_shift

The exponent the channel is downsampled by on each axis. TODO(lode): expand this comment to match the JPEG XL specification, specify how to upscale, how to round the size computation, and to which extra channels this field applies.

name_length

int name_length

Length of the extra channel name in bytes, or 0 if no name. Excludes null termination character.

alpha_premultiplied

boolean alpha_premultiplied

Whether alpha channel uses premultiplied alpha. Only applicable if type is JXL_CHANNEL_ALPHA.
