Convert APNG (Animated PNG) to PCD

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 PCD (Photo CD) file extension, developed by Kodak, is used for storing digital images on a Photo CD. This format was introduced in the early 1990s to digitize and archive physical photographs. PCD files contain high-resolution images scanned from film, typically at resolutions of 3072 x 2048 pixels or higher. These files are utilized for preserving, viewing, and editing images using compatible software. The PCD format supports 24-bit color and includes multiple resolutions within a single file, facilitating versatile image processing and archival purposes.
