Convert CAL to SVGZ

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.

SVGZ, or Scalable Vector Graphics Compressed, is a file extension for compressed SVG files, utilizing the GZIP compression method. Introduced to optimize web performance, SVGZ retains the scalability and resolution independence of SVG while reducing file size, leading to faster load times and reduced bandwidth usage. This format is particularly valuable in web development, digital graphics, and applications requiring efficient transmission and rendering of vector graphics. SVGZ emerged as part of efforts to enhance web technologies, catering to the increasing demand for high-quality, scalable visuals in a more efficient manner.
