BrightnessContrastParams type
The parameters of a BrightnessContrast effect: the brightness and the contrast.
The type mirrors the GDI+ BrightnessContrastParams structure. A BrightnessContrast takes it in its constructor and in its Parameters property.
Fields
| Field | Type | Meaning |
|---|---|---|
| brightness | Long | The change of brightness, from -255 to 255. 0 changes nothing. |
| contrast | Long | The change of contrast, from -100 to 100. 0 changes nothing. |
Creating
Syntax: params = BrightnessContrastParams( brightness, contrast )
- brightness, contrast
- required Long values for the fields.
Dim user As GdiPlusUser = GdiPlusUser()
Dim p As BrightnessContrastParams = BrightnessContrastParams(40, -10)
Debug.Print p.brightness & " " & p.contrast
Dim fx As BrightnessContrast = BrightnessContrast(p)
Debug.Print fx.LastResult
' Output:
' 40 -10
' 0
