Function libjxl_sys::JxlDecoderSetPreviewOutBuffer

pub unsafe extern "C" fn JxlDecoderSetPreviewOutBuffer(
    dec: *mut JxlDecoder, 
    format: *const JxlPixelFormat, 
    buffer: *mut c_void, 
    size: usize
) -> JxlDecoderStatus

Sets the buffer to write the small resolution preview image to. The size of the buffer must be at least as large as given by JxlDecoderPreviewOutBufferSize. The buffer follows the format described by JxlPixelFormat. The preview image dimensions are given by the JxlPreviewHeader. The buffer is owned by the caller.

@param dec decoder object @param format format of pixels. Object owned by user and its contents are copied internally. @param buffer buffer type to output the pixel data to @param size size of buffer in bytes @return JXL_DEC_SUCCESS on success, JXL_DEC_ERROR on error, such as size too small.
