+ + + + + + +2001, 2002, 2003 +Michael v.Ostheim + + + +&FDLNotice; +28/08/2003 +1.00.20 + + + +&kgamma; is a simple tool for monitor gamma correction. + + + +KDE +KGamma +Monitor +Calibration +Gamma + + + + + +Introduction + +This document describes &kgamma; version 1.0.2 (KDE 3.2) +&kgamma; is a tool for monitor gamma correction. With proper gamma +settings, your display (websites, images, etc.) will look the same on your +monitor as on other monitors. +&kgamma; allows you to alter the monitor's gamma correction of +XFree86. But that's not all to do. For good results you have to set the +correct brightness, contrast and color balance of your monitor. This +may be difficult and you have to repeat every step several times. +For perfect results you need really good (and expensive) hardware. +This are system settings, please do not use &kgamma; to manipulate your +image files. + + + +Using KGamma + +Setting Gamma Correction +Use the four sliders to define the gamma correction either as a single +value, or separately for the red, green and blue components. The XFree86 +default setting for gamma is 1.00 (Mac 1.80, WinXX 2.20). The test images help +you to find proper settings. +To store the gamma settings system wide, enable the option 'Store +settings to XF86Config'. The system settings will be restored at next XFree86 +startup. You need root access to use this option. Use this if you want to +correct the gamma settings for all users and graphical environments on this +machine. +To store the gamma settings to your personal KDE configuration, do not +enable that option. The user settings will be restored at next KDE startup and +replace temporary the system gamma settings. The system settings are not removed by +that and will be restored at next XFree86 startup. +On multi head systems, select the screen you want to alter with the combo +box. This will also work with xinerama enabled. If you want to set all screens +to the same gamma values, enable the 'Sync screens' option. On systems with only +one screen this option will take no effect. + + + +Gray Scale Test Image +You should be able to see the following: + + + +A gray scale with 20 different sections + + +The darkest section pure black + + +The lightest section pure white + + +No hint of any color in the gray tones + + + +If you can't see all of the 20 sections, use your monitors contrast settings +or the "Gamma" slider of &kgamma; to correct this. If black is not pure black, +try to darken the monitor, if white is not pure white, try to lighten +it. If you see any colors in the gray tones alter the color balance settings of +your monitor or the "Red", "Green" and "Blue" slider of &kgamma;. + + + +RGB Scale Test Image + +You should be able to see three strips, each with 16 sections of red, +green or blue tones. The darkest sections should be pure black, the brightest +should be pure red, green or blue. If you don't see all sections of +a color strip, try to lighten or darken this color. + + + +CMY Scale Test Image + +You should be able to see three strips, each with 11 sections of cyan, +magenta or yellow tones. The brightest sections should be pure white, the darkest +should be pure cyan, magenta or yellow. + + + +If you can't see all cyan sections, try to lighten or darken red + + +If you can't see all magenta sections, try to lighten or darken green + + +If you can't see all yellow sections, try to lighten or darken blue + + + + + +Advanced Test Images + +The following three pictures shows you the abilities of your monitor at +three points of the gray spectrum. If you can't see all of the details, +don't be worry, or buy better hardware. + + +Dark Gray Test Image + +You should be able to see 10 different rectangles of dark gray within a +black box. The chart shows you 1% steps from black. + + + +Mid Gray Test Image + +This picture shows you 11 gray rectangles within a 50% gray box. You should be +able to see all of the rectangles except the middle one. The rectangles represent +the steps from 45% to 55% gray. + + + +Light Gray Test Image + +You should be able to see 10 different rectangles of light gray within a white box. +The chart shows you 1% steps from white. + + + + + + + +Credits and License + + +&kgamma; + + +Program copyright 2001, 2002, 3003 Michael v.Ostheim ostheimm@users.berlios.de + + + +Documentation copyright 2001, 2002, 2003 Michael v.Ostheim ostheimm@users.berlios.de + + + + +&underFDL; +&underGPL; + + + +Installation + +&kgamma;'s home site is +http://kgamma.berlios.de/index2.php + + + +Compilation and Installation + + +In order to compile and install &kgamma; on your system, type the following in the base +folder of the &kgamma; distribution: + +% ./configure +% make +% make install + + + + + + +&documentation.index; + + -- cgit v1.2.1
