Function JxlDecoderGetColorAsICCProfile 

pub unsafe extern "C-unwind" fn JxlDecoderGetColorAsICCProfile(
    dec: *const JxlDecoder,
    target: JxlColorProfileTarget,
    icc_profile: *mut u8,
    size: usize,
) -> JxlDecoderStatus

Outputs ICC profile if available. The profile is only available if JxlDecoderGetICCProfileSize returns success. The output buffer must have at least as many bytes as given by JxlDecoderGetICCProfileSize.

Parameters

• dec: decoder object
• target: whether to get the original color profile from the metadata or the color profile of the decoded pixels.
• icc_profile: buffer to copy the ICC profile into
• size: size of the icc_profile buffer in bytes

Returns

• JxlDecoderStatus::Success: if the profile was successfully returned
• JxlDecoderStatus::NeedMoreInput: if not yet available
• JxlDecoderStatus::Error: if the profile doesn’t exist or the output size is not large enough.
