Macro Definition Documentation

#define RFB_BUF_SIZE   8192

Definition at line 212 of file rfbclient.h.

#define RFB_BUFFER_SIZE   (640*480)

Note that the CoRRE encoding uses this buffer and assumes it is big enough to hold 255 * 255 * 32 bits -> 260100 bytes.

640*480 = 307200 bytes. Hextile also assumes it is big enough to hold 16 * 16 * 32 bits. Tight encoding assumes BUFFER_SIZE is at least 16384 bytes.
