Convert CAL to DIB

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.

A Device Independent Bitmap (DIB) is a format for storing bitmap graphics, ensuring compatibility across different devices and platforms. Its primary use is to enable consistent image representation, regardless of the display hardware or software. Originating from early Windows operating systems, DIBs allowed developers to create graphics that would render accurately on various hardware. Today, DIBs are integral in applications needing uniform image display and manipulation, maintaining their relevance in diverse technological contexts.
