The following screen shot shows properties of the clipping objects relative to the layer (InverseClip property is False, by default):
The following screen shot shows properties of the clipping objects relative to the layer (InverseClip property is True):
To define a picture clip region over the layer you can use any of the following properties:
- Name, Indicates the picture to be used as a mask/clip.
- DisplayAs, Retrieves or sets a value that indicates the way how the graphic is arranged on the mask/clip.
- AlphaFrom, Gets or sets a value that specifies the alpha-byte to start clipping the picture from.
- AlphaTo, Gets or sets a value that specifies the alpha-byte to end clipping the picture to.
To specify the position / size of the picture clip object you can use any of the following properties:
- Left, Specifies the left position / expression of the clip, relative to the layer.
- Top, Specifies the top position / expression of the clip, relative to the layer.
- Width, Specifies the width value / expression of the clip, relative to the layer.
- Height, Specifies the height value / expression of the clip, relative to the layer.
To move the clipping region you can use any of the following properties:
- OffsetX, Specifies the x-offset expression / value of the clip, relative to the layer.
- OffsetY, Specifies the y-offset expression / value of the clip, relative to the layer.
If none of these properties are calling no clipping is applied to layer.
The InverseClip property inverses the current clipping region, so anything that was included in the clipping region will be excluded, and reverse.
For instance, having the following gauge:
a picture clip region over the background layer shows as:
when the source picture is:
