Convert RLA to SIX

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 SIX file extension, short for "six pixels", is a bitmap graphics format developed by Digital Equipment Corporation (DEC) for their terminals and printers. Introduced initially to send bitmap graphics to DEC dot matrix printers like the LA50, SIX later facilitated the transfer of soft fonts to terminals such as the VT220. This format encodes images using a series of six-pixel-high patterns, making it efficient for transmitting graphics over 7-bit serial links. Rediscovered around 2010, SIX remains in use with modern terminal emulators for tasks like video playback.
