How fireworks create an empty mask

You can add an empty mask to an object. It can be either a "display mask", an area that displays a mask, or a "hidden mask", where the shaded area is hidden.

(An empty mask is primarily used for bitmap editing mode masking)

Use the show All/Hide All command

The show all command adds an empty full mask, which is all displayed by the Masked object. Hide all commands to add an empty full mask so that the objects are all obscured.

(with subsequent bitmap operations, you can create a different matte image. For example, a part of a shaded object is displayed, or a part of a masked object is obscured.)

Create an empty mask using the show all and hide all commands:

1, choose to be obscured objects.

2. Create an empty cover Photo:

Select Menu Modify > Mask > Reveal All (Modify-> mask-> display all) to display the Masked object.

Select the menu Modify > Mask > Hide All (Modify-> mask-> hide All) to hide the masked object.

3, in the layer panel of the object display block select the object.

4. Select the drawing tool to edit the mask image.
