Topic_02: Transparency Masks

  1. Place the image: File > Place > Select image from file (short cut: ctrl + shift + p)
  2. Open the Transparency Window located on the tool bar located on the right of the screen.

    (It can also be accessed from top toolbar through Window>Transparency.)

  4. Click on the icon located in the top right of the window. A drop down menu should appear. Click “Make Opacity Mask.”

    Note: Your image appears to disappear from the main paper space, however you can still see the outline of it by hovering your mouse over it. Also note the preview in the window now shows an extra black box to the right of your image. This is your mask and it currently is completely covering your image.
  5. Click the link icon between the two boxes to un-link the mask and image.
  6. Select the mask (black box preview) and select the basic shape tool such as Rectangle or Circle tools, or custom shape tool such as the Pen tool, setting the stroke to none, and fill to WHITE. You should see part of your image depending on your shape.

  11. Change the angle to any desired direction of gradient.

    Note: In gradients, black means 0% opaque, white means 100% opaque. Adjusting the two slider allows to control the range of the opacity.
