The most common formats are 24 and 16 bit "true-color" values, and 8-bit "color map" representations, where an arbitrary map converts the color number to RGB values. Encoding refers to how a rectangle of pixels are sent all pixel information in VNC is sent as rectangles. All rectangles come with a header giving the location and size of the rectangle and an encoding type used by the data which follows. These types are listed below. All clients are required to support this encoding type.
Raw is also the fastest when the server and viewer are on the same machine, as the connection speed is essentially infinite and raw encoding minimizes processing time. The Copy Rectangle encoding is efficient when something is being moved. The only data sent is the location of a rectangle from which data should be copied to the current location. Copyrect could also be used to efficiently transmit a repeated pattern. With this encoding, a sequence ofidentical pixels are compressed to a single value and repeat count.
In VNC, this is implemented with a background color, andthen specifications of an arbitrary number of sub rectangles andcolor for each. This is an efficient encoding for large blocks ofconstant color. This is a minor variation on RRE, using a maximum of xpixel rectangles. This allows for single-byte values to be used,reducing packet size. This is in general more efficient, because the savings from sending 1-byte values generally outweighs thel osses from the relatively rare cases where very large regionsare painted the same color.
Here, rectangles are split up in to 16x16 tiles, which aresent in a predetermined order. The data within the tiles is senteither raw or as a variant on RRE. Hextile encoding is usually the best choice for using in high-speed network environments e.
Ethernet local-area networks. Zlib is a very simple encoding that uses zlib library tocompress raw pixel data. This encoding achieves good compression, but consumes a lot of CPU time. Support for this encoding is provided for compatibility with VNC servers that might notunderstand Tight encoding which is more efficient than Zlib innearly all real-life situations. Like Zlib encoding, Tight encoding uses zlib library tocompress the pixel data, but it pre-processes data to maximizecompression ratios, and to minimize CPU usage on compression.
Also, JPEG compression may be used to encode color-rich screenareas see the description of -quality and -nojpeg optionsabove. Tight encoding is usually the best choice forlow-bandwidth network environments e. This means it favors speed over compression ratio. Toggle Full Screen Mode. Show Connection Options Refresh Screen.
