2010-07-26ui: move all ui components in ui/Corentin Chary
Move sdl, vnc, curses and cocoa UI into ui/ to cleanup the root directory. Also remove some unnecessary explicit targets from Makefile. aliguori: fix build when srcdir != objdir Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-06-01vnc: add basic tight supportCorentin Chary
Add support for tight encoding [1]. This patch only add support for "basic" tight compression without any filter. [1] http://tigervnc.org/cgi-bin/rfbproto#tight-encoding. Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-06-01vnc: return the number of rectanglesCorentin Chary
Some encodings like tight supports tiling (spliting in multiple sub-rectangles). So we needed a way to tell vnc_update_client() how much rectangles are in the buffer. zlib, raw and hextile always send a full rectangle.

2010-06-01vnc: remove a memory leak in zlibCorentin Chary
Makes sure we free all ressources used in zlib encoding (zlib stream and buffer). Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-06-01vnc: don't clear zlib stream on set_encodingCorentin Chary
On init, values are already NULL, but we shouldn't try to reset them each time a client send a set encoding command because this break everything. For example, libvncclient re-send a set encoding command if the framebuffer is resized. This fix framebuffer resizing for zlib encoding.

2010-06-01vnc: adjust compression zstream levelCorentin Chary
Adjust zlib compression level if needed by calling deflateParams. Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-06-01vnc: only use a single zlib streamCorentin Chary
According to http://tigervnc.org/cgi-bin/rfbproto#zlib-encoding zlib encoding only uses a single stream. Current implementation defines 4 streams but only uses the first one. Remove them and only use a single stream. Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-05-03vnc: split encoding in specific filesCorentin Chary
This will allow to implement new encodings (tight, zrle, ..) in a cleaner way. This may hurt performances, because some functions like vnc_convert_pixel are not static anymore, but should not be a problem with gcc 4.5 and the new -flto.
