Set a Readout Value
Double Tap (or Two finger tap) a Readout to manually set
the color value of the source of a readout.
Not all readout types allow setting a value, since not all types can
be be converted back to a Tri-stimulus CIE value.
There are two purposes for setting a value:
To operate as a color calculator. By setting up
readouts of the measured value in the color spaces you want to
convert between, you can enter a value in one, and immediately see
the equivalent value on the others.
To set a reference value to check a measurement against, or to
adjust the equipment you are measuring. For instance, by setting a
Readout to have the measurement reference as the source and to be
in RGB space with a Rec709 colorspace, you can enter the target
value in RGB space, thereby implicitly setting an XYZ reference
value. If one of the other readouts is set to the measurement
source and RGB Adjustment value, then you have a direct means of
making adjustments to a display against the RGB target value.
You can paste from the Clipboard by long pressing in an entry.
If the Clipboard contains a number that suits the type of entry, it
will be inserted at the cursor in the usual way.
If the Clipboard contains at least 3 number that suits the type of
entry, they will replace the current 3 values. This is allows
convenient copy and paste between a Readout value and the Set Value
dialog.
Note that the Configurable RGB
colorspace Readout:
- Has special behavior
after setting a value.
- Doesn't normally clip or limit the values you enter, which
may result in extrapolated or nonsensical tri-stimulus values.
- The values used with the Send
RGB to TPG option enabled will end up being clipped to the
device range.
