Function libjxl_sys::JxlEncoderSetBasicInfo

pub unsafe extern "C" fn JxlEncoderSetBasicInfo(
    enc: *mut JxlEncoder, 
    info: *const JxlBasicInfo
) -> JxlEncoderStatus

Sets the global metadata of the image encoded by this encoder.

If the JxlBasicInfo contains information of extra channels beyond an alpha channel, then @ref JxlEncoderSetExtraChannelInfo must be called between JxlEncoderSetBasicInfo and @ref JxlEncoderAddImageFrame. In order to indicate extra channels, the value of info.num_extra_channels should be set to the number of extra channels, also counting the alpha channel if present.

@param enc encoder object. @param info global image metadata. Object owned by the caller and its contents are copied internally. @return JXL_ENC_SUCCESS if the operation was successful, JXL_ENC_ERROR or JXL_ENC_NOT_SUPPORTED otherwise
