Constant libjxl_sys::JXL_DEC_NEED_IMAGE_OUT_BUFFER

pub const JXL_DEC_NEED_IMAGE_OUT_BUFFER: JxlDecoderStatus = 5;

The decoder requests an output buffer to store the full resolution image, which can be set with @ref JxlDecoderSetImageOutBuffer or with @ref JxlDecoderSetImageOutCallback. This event re-occurs for new frames if there are multiple animation frames and requires setting an output again.
