Convert PBM to EPI

The PBM (Portable Bitmap) file extension, part of the Netpbm project, originated in the late 1980s to facilitate efficient and portable graphics file interchange. Primarily, PBM files are used to store monochrome bitmaps in a simple ASCII text format, ensuring easy compatibility across different systems and platforms. This format supports only black-and-white imagery, making it particularly useful in scenarios where simplicity and minimalism are prioritized, such as in Unix environments for bitmap manipulation and transfer. Its historical significance lies in promoting a standardized approach to bitmap graphics in early computer technology.

The EPI file extension stands for Encapsulated PostScript Interchange, a format developed by Adobe in the late 1980s. It facilitates the integration of vector graphics and text into documents for high-resolution printing. EPI files, a variant of EPS, are primarily used in graphic design and desktop publishing to ensure consistent and scalable image quality. This format employs Adobe's PostScript language to describe the appearance of a single page, making it ideal for embedding illustrations in various documents.
