Additionally -@command{libgamma} have support for Windows -Graphics Device Interface (Windows GDI) under -Windows and Quartz using CoreGraphics under OS X. -However Windows GDI and Quartz/CoreGraphics do -not receive first-party testing on their target -platforms but do receive first-party testing -using a compatibility layer that translates -the calls to RandR calls. Neither does -@command{libgamma}, currently, receive testing -on any of the BSD:s, it is only tested on GNU/Linux. - -Furthermore @command{libgamma} provides a dummy -method that can be used to ignore adjustments -and can be controlled from another program to -pretend like the environment has changed. This -can be used test how well your software handles -such events. It can also be configured at runtime -to use another adjustment method such as RandR. - - - -@node Jargon -@chapter Jargon - -@command{libgamma} uses a small jargon, -parts of which is loaned from X.org, -and some is commonly used jargon. - -@table @asis -@item adjustment method [libgamma] -A combination of the display server -and a protocol used to tell to the -display server. - -@item display server [X.org] -The program used to display graphical -elements to the monitors. In @command{libgamma} -we also call the non-graphical environment -a display server. - -@item display [X.org] -@itemx site [libgamma] -An instance of a display server. -Non-graphical environment are only -covered by `site'. - -@item screen [X.org] -A group of CRTC:s within a display. - -@item CRTC -@itemx cathode ray tube controller -Controller for the output on monitor. -Mapping from CRTC:s to encoders is an injection. - -@item monitor -The physical medium used to display -text and graphics. - -@item partition [libgamma] -Umbrella term for `screen' and -`graphics card'. - -@item page [libgamma] -The desktop workspace or virtual -terminal that is displayed on a CRTC. -(This jargon is not currently used, -but is reserved for future features.) - -@item output [X.org] -A connector and its encoder. - -@item connector -Physical port on the graphics card where -a monitor can be plugged in. If and only -if the connector is disabled it does not -have a port and does not have a CRTC. - -@item encoder -Translation layer between CRTC:s and connectors. - -@item gamma ramp -@itemx colour curve -A lookup table that translates an encoded -value for a subpixel into its output value. - -@item subpixel -@itemx colour channel -One of the three colours that makes up a pixel: -red, green or blue. - -@item gamma ramp size -@itemx gamma stops -The number of possible values on the encoding -axis of a gamma ramp. - -@end table - - - -@node Compiling -@chapter Compiling - -The build @command{libgamma} you will need -to run @command{./configure} before you -run @command{make}. @file{./configure} is -not a configuration script from the GNU build -system, rather it is just a simple shell script. -Each adjustment method needs selected, if none -are selected no adjustment method will be compiled -into @command{libgamma}.
