The following effects are available for graphic objects:

Mask

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.

Note
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:

Effect_Mask_parameters

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.

Effect_Mask

The folloving picture illustrates both variants of applying the mask effect:

Effect_Mask_applied

All the objects outside the group remain visible regardless of whether they are in the background or foreground respectively to the group.

Gradient

This effect adds a gradient to plate objects. The gradient can be applied for color and/or opacity of the object.

Effect_Gradient

The gradient effect has the following parameter:

Effect_Gradient_parameters
  • Mode – determines the pattern in which the gradient fills the image. Currently only linear gradient is available.

  • 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 percents from the edge of the plate object, starting from which the gradient is applied.

  • End Point – determines the point in percents 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.
