1.18.7.1.3.1 Example 1: Inverting an Image
To get an inverted 8 bit mono image like shown in Figure 1, you can set the LUT using wxPropView (p. 68). After
starting wxPropView (p. 68) and using the device,
1. Set "LUTEnable" to "On" in "Setting -> Base -> ImageProcessing -> LUTOperations".
2. Afterwards, set "LUTMode" to "Direct".
3. Right-click on "LUTs -> LUT-0 -> DirectValues[256]" and select "Set Multiple Elements... -> Via A User
Defined Value Range".
This is one way to get an inverted result. It is also possible to use the "LUTMode" - "Interpolated".
4. Now you can set the range from 0 to 255 and the values from 255 to 0 as shown in Figure 2.
