Convert BMP to CAL

Understanding bmp and cal file formats

BMP (Bitmap Image File) is a widely used raster graphics image file format developed by Microsoft. It stores digital images independently of the display device, making it a popular choice for storing high-quality, uncompressed images on Windows systems.

CAL (CALS Raster Graphic File) is a raster image format standardized by the U.S. Department of Defense. It is primarily used for document imaging and technical drawings, especially in engineering and government sectors. CAL files are monochrome and optimized for high-quality line art and scanned documents.

How to convert bmp to cal

Converting a BMP file to a CAL file involves changing the image from a general-purpose bitmap format to a specialized monochrome raster format. This process may require converting the image to black and white and ensuring it meets CALS specifications.
