The following effects are available for graphic objects:
This effect can be applied to a plate or text object contained in a group to allow partial or total occlusion of other objects in this group. Objects can be occluded within the body of the scene by a mask – allowing items to appear on screen from any position, or to remove sections from an object.
|The objects in the tree, that are placed below the object with the applied "Mask" effect, become the compound mask for this object.|
With the "Mask" effect applied, the luminance value of the object acting as a mask defines the appearance of all other underlying objects: a white pixel of the mask makes the target pixel completely visible, a black pixel of the mask makes a target pixel transparent.
The mask effect has the following parameter:
Select the "Invert" option to use the reversed mask.
For example, a group contains an image and a white color plate object with 80% opacity.
The folloving picture illustrates both variants of applying the mask effect:
All the objects outside the group remain visible regardless of whether they are in the background or foreground respectively to the group.
This effect adds a gradient to plate objects. The gradient can be applied for color and/or opacity of the object.
The gradient effect has the following parameter:
Mode – determines the pattern in which the gradient fills the image.
Edge Mode – specifies how the color will be applied to the areas not covered by the gradient if "Begin Point" is greater than 0% and "End Point" is less than 100%.
Direction – determines the gradient transition direction.
Begin Point – determines the point in percent from the edge of the plate object, starting from which the gradient is applied.
End Point – determines the point in percent from the edge of the plate object, at which the gradient will end.
Begin Color – determines the color for the start of the gradient.
End Color – determines the color for the end of the gradient.
