Convert G4 to XPM

The G4 file extension, standing for CCITT Group 4 Fax Image, is a specialized format used primarily for storing black-and-white facsimile (fax) images. Its origins trace back to the Consultative Committee for International Telegraphy and Telephony (CCITT), now known as the ITU-T, which developed the Group 4 standard in the 1980s to improve fax transmission efficiency over digital networks. This format employs a high compression ratio to reduce file size while maintaining image quality, making it ideal for archiving documents and transmitting faxes in professional and business environments.

The XPM (X PixMap) file extension is a format used for storing pixmap images, primarily in the X Window System for Unix-based systems. Developed in the late 1980s, it allows for the storage of images in plain text, making it human-readable and editable. XPM files are mainly utilized for defining icons and graphical elements in software applications. They support transparency and can be easily integrated into programming languages such as C, enhancing the customization and visual appeal of user interfaces. The format's simplicity and flexibility have cemented its role in software development and graphical design.
