Adjustment and Measurement Dialog
LProf is an open source application that creates ICC profile
for cameras, scanners and monitors.
This dialog is used to perform various functions related to
calibration and measurement of our display. This is where you do
actual measuremetns using your measurement device. The dialog is
divided into several areas that have different fuctions.
Measurement Area
In the center of the screen is the measurement area. This is
the gray square area in the middle of the screen. The measurement
area can be resized and moved around using the slider ocntrols to the
left, right and above the measurement area. The slider to the
right controls the measurement areas size and the other two control
it's position.
Go and Done Buttons
After you have sized and positioned the measuremetn area with the
slider and placed you measurement device over the measurement area you
can start the measurement process by clicking the "Go" button. If
you are perorming one of the display adjustment processes such as
adjusting the white point or black level you can tell this dialog you
are done by clicking the 'Done". If you are running the
calibration or measurement process pressing the "Done" button will
abort the process.
Progress Bar
The progress bar at the buttom of the dialog is used for two different
purposes. If you are running one of the adjustment process it is
used to indicated measurement activity and will jump approximately 20%
after each measurement. It will cycle back to 0% after reaching
100%. It you are running a calibration or measurement process it
will indicate how far into the process you are and the process is
complete when it reaches 100%.
Meassage Area
Just above the progress bar and the buttons is the message area.
This area is used to display messages including messages about
what to do and any error messages that happen during the adjustment,
calibration or measurement process.
Adjustment Indicator Bars
If you are doing one of the adjust steps you will see either one gray
vertical bar on the right side of the dialog or three red, green and
blue indicators on the left side of the dialog. The gray bar is
used while adjusting the black level or the white level to guide
setting the display controls to get the correct setting of the contrast
and brightness controls. The red, green and blue indicators are
used for setting the white point and black point as a guide to help in
setting the RGB gain controls and for black point the RGB brightness
controls.
White Point and Delta E
If you are setting either the white point or the black point below the
RGB adjustment indicator bars you will see a White point and a Delta E
display. These will indicate the current color temperature and
the Delta E of the current white/black point from the desired setting.
