Tutorial: How to Convert Raw CCITT Data into a TIFF Image Using Java

CCITT is a compression format used for black-and-white image data, commonly found in PDF files and the TIFF file format. A developer tutorial on DEV Community explains how raw CCITT data can be converted into a valid TIFF image by appending specific metadata bytes and saving the file with a .tif extension. The guide provides a Java-based implementation, though the author notes the logic can be adapted to other programming languages. CCITT data can be manually extracted from PDF XObjects along with dictionary parameters such as K and isBlack values. The tutorial also cautions that extracted raw images may differ from their PDF counterparts, as they could appear inverted, clipped, or otherwise altered.
