Convert CAL to GIF

The CAL file extension, known as CALS (Continuous Acquisition and Life-cycle Support) Type 1 Image, is a 1-bit black-and-white raster image format developed by the U.S. Department of Defense in the mid-1980s to standardize graphics data interchange for military documentation. It is primarily used for storing and sharing monochrome images while retaining orientation metadata. The format supports both uncompressed and compressed (using CCITT Group 4 compression) images.

The Graphics Interchange Format (GIF) is a bitmap image format developed by CompuServe in 1987. It is widely used for its support of animated images, allowing for the compression of graphics with low file sizes and without compromising quality. It's particularly popular on the internet for memes, short animations, and simple graphics due to its ability to loop animations seamlessly. GIFs support up to 256 colors and use the LZW compression algorithm to minimize file size. The format's historical significance lies in its ability to efficiently store and transmit images in an era of slower internet speeds and remains a staple in digital communication and web design today.
