Convert X3F to EPSI

The X3F file extension, associated with Sigma Digital Camera Raw Image File, is a proprietary format created by Sigma Corporation for cameras with Foveon X3 sensors. X3F files store raw image data, capturing full-color information at each pixel for enhanced color accuracy and detailed post-processing. This format includes metadata, thumbnails, and preview images, offering photographers comprehensive control over their images. While primarily processed with Sigma Photo Pro software, X3F files are also supported by plugins for popular photo editing software like Adobe Photoshop.

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.
