Version 1.6.5.0
If a mask is used in a layer its position is automatically synchronised with the media for that layer.
As the layer is scaled, positioned or rotated, the mask is too. This greatly simplifies the use of
masks.
Any media can be used as an independent mask by loading it into a layer above the layer to be
masked. If the media has transparency, this will reveal the layer below automatically. If you wish to
control how the mask works, the
Mask

×
=
The examples above have the mask intensity set to full. Reducing the mask's intensity reduces its
effect. Here is a mask at 0.33 intensity:
