Convert RLA to SUN

The RLA file extension stands for Run-Length Encoded, Version A, a bitmap image format developed by Alias/Wavefront. It is primarily used for storing raster graphics with run-length encoding to compress image data efficiently. RLA files are compatible with various image viewing and editing software, such as XnView. This format was popularized in the early days of computer graphics for its ability to handle arbitrary image channels and support efficient storage of large images.

The Sun Raster (SUN) file extension, originating from Sun Microsystems, is a bitmap image format used primarily on SunOS systems. Known for its versatility in storing raster graphics, it supports various color depths, from monochrome to 24-bit true color. Initially created for the Sun workstation's image processing software, it facilitated efficient graphical data manipulation and transmission. Over time, its straightforward structure and compatibility with different Unix-based systems ensured its adoption in diverse graphic applications. Today, while largely historical, the SUN file format remains an important part of the legacy of early computer graphics development.
