ocr: TIFF50 In TIFF, individual fields are identified with a unique tag. This allows particular fields tol bej present or absent from the file as required by the application. For an explanation of the rationale behind using a tag structure format, see. Appendix A. A TIFF: file begins with an 8-byte "image file header" that points to one or more "image file directories." The image file directories contain information about the images, as well as pointers to the actual image data. See Figure 1. An Akdus/Microsoft Technical Memorandum: 8/8/88 Page3
