Convert ICB to APNG (Animated PNG)

The ICB file extension, associated with Targa Graphics, stands for Image Capture Board. It was originally used with the AT&T EPICenter Image Capture Board video card and software like ICB-PAINT and TARGA-PAINT. This format is a raster graphics file used for storing and exchanging deep-pixel images, supporting 8, 16, 24, and 32 bits per pixel. Developed by Truevision Inc., it played a significant role in early computer graphics for high-color display on IBM-compatible PCs.

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.
