Convert PTIF to G3

The PTIF (Pyramid Encoded TIFF) file format, developed by Image Magick, is a specialized variant of the TIFF image format designed to store multiple resolutions of the same image within a single file. This enables efficient zooming and panning in applications without losing image quality. PTIF files are commonly used in geospatial imaging, remote sensing, and medical imaging due to their ability to handle large, high-resolution images efficiently. The format was introduced to address the need for handling large image datasets more effectively in these fields.

The G3 file extension refers to the CCITT Group 3 Fax Image, a standardized format developed by the Consultative Committee for International Telegraphy and Telephony (CCITT), now known as ITU-T. This format was created to efficiently compress black-and-white fax documents for transmission over telephone lines. It employs a method called Modified Huffman Coding for data compression, enabling reduced transmission time and bandwidth usage. G3 was widely adopted in the 1980s and 1990s as the primary standard for fax transmissions, ensuring compatibility across different fax machines and systems.
