Convert SRF to CAL

The SRF (Sony Raw File) is a RAW image file format used by Sony digital cameras, such as the DSC-F828 model, to store uncompressed, unaltered images captured by the camera's sensor. Introduced in January 2004, SRF files preserve high-quality image data, offering photographers greater flexibility in post-processing compared to compressed formats like JPEG. Over time, Sony developed subsequent formats like SR2 and ARW to enhance features and compression methods.

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.
