• CoRRE
– A variation of RRE, using a maximum of 255x255 pixel rectangles, allowing for
single-byte values to be used. More efficient than RRE except where very large regions are
the same color.
• Hextile
– Rectangles are split up in to 16x16 tiles of raw or RRE data and sent in a
predetermined order. Best used in high-speed network environments such as within the
LAN.
• Zlib
– Simple encoding using the zlib library to compress raw pixel data, costing a lot of
CPU time. Supported for compatibility with VNC servers that might not understand Tight
encoding which is more efficient than Zlib in nearly all real-life situations.
• Tight
– The default and the best encoding to use with VNC over the Internet or other low-
bandwidth network environments. Uses zlib library to compress pre-processed pixel data
to maximize compression ratios and minimize CPU usage.
