Convert EPSI to SUN

EPSI, standing for Encapsulated PostScript Interchange, is a file extension used primarily in the printing and graphic design industries. It stores PostScript data along with a low-resolution preview in bitmap format, facilitating the visualization of graphic content in layout applications without needing to interpret the complex PostScript code. Introduced in the 1980s by Adobe Systems, EPSI files serve as a bridge between different software applications, ensuring consistent and high-quality output in various publishing workflows. Their efficiency and adaptability have made them a standard for exchange of graphic data in professional environments.

The Sun Raster (SUN) file extension, originating from Sun Microsystems, is a bitmap image format used primarily on SunOS systems. Known for its versatility in storing raster graphics, it supports various color depths, from monochrome to 24-bit true color. Initially created for the Sun workstation's image processing software, it facilitated efficient graphical data manipulation and transmission. Over time, its straightforward structure and compatibility with different Unix-based systems ensured its adoption in diverse graphic applications. Today, while largely historical, the SUN file format remains an important part of the legacy of early computer graphics development.
