caption: Extracting Data from the Line Buffer
exif: {"Image DocumentName": "Extracting Data from the Line Buffer", "Image ImageDescription": "To extract data from the line buffer, call a read procedure one or more times. For example, if bv4 is a bit_vector of length four, the call. read(buff, bv4) extracts a 4-bit vector from the buffer, sets bv4 equal to this vector, and adjusts the pointer buff to point to the next character in the buffer. Another call to read will then extract the next data object from the line buffer. 15/11/2018.", "Image XResolution": "200", "Image YResolution": "200", "Image ResolutionUnit": "Pixels/Inch", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
