Convert APNG (Animated PNG) to XPM

Animated Portable Network Graphics (APNG) is an extension of the Portable Network Graphics (PNG) format designed to support animated images. Introduced in 2004, APNG allows for animated sequences while retaining backward compatibility with non-animated PNG files. This format is utilized for its lossless compression, making it ideal for web graphics where image quality is paramount. APNG files are widely used for animated icons, logos, and other elements that benefit from high-quality animations without the artifacts common in GIF files. Its concise, efficient structure makes it a preferred choice among developers and designers focused on optimizing web performance.

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.
