Abstract
A web client may receive a run-length encoded packet of graphics data from a Remote Desktop Protocol server via a web-socket server. The web client may determine a run-length encoding algorithm for the packet based on a first color space associated with the packet. The web client may decompress the packet based on the determined run-length encoding algorithm, where decompressing the packet involves determining a plurality of commands to be performed on a canvas associated with the web client. The web client may render the graphics data on the canvas using the plurality of commands, wherein the graphics data is associated with a graphical interface for viewing and interacting with a remote desktop.
