- Increment
- Single
Required Single. Specifies how much to change the value of the Contrast property for the picture. A positive value increases the contrast; a negative value decreases the contrast.
Remarks
You cannot adjust the contrast of a picture past the upper or lower limit for the Contrast property. For example, if the Contrast property is initially set to 0.9 and you specify 0.3 for the Increment argument, the resulting contrast level will be 1.0, which is the upper limit for the Contrast property, instead of 1.2.
