The ORA file extension stands for OpenRaster Image File, a format designed for the exchange of layered raster graphics between different software applications. Proposed in 2006 by developers from KDE and Krita, OpenRaster aims to provide an open alternative to proprietary formats like Adobe's PSD. The format encapsulates image layers, blending modes, and metadata within a ZIP archive containing XML and PNG files. Its primary use is to facilitate interoperability among various graphic editors, ensuring that complex image data can be shared and edited across different platforms.
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.
