Change transparency

Belongs to

Allows you to modify the transparency of the objects in a PDF file.

You can:

Modify the alpha channel of a fill and/or stroke, by moving the sliders to the desired percentage. Note that, to gain full opacity, you should move the slider to 100%.
Change the blending modes.
This will change the way in which the colors of a transparent object on top blend with the colors of underlying objects.
To select the blending modes you want to apply, proceed as follows:
1. Select a blending mode under Available.
2. Click Add to move it to the Selected list.
3. Repeat steps 1-2 as required.
  The blending modes will be applied in the order as they appear in the Selected list.
Turn on or off Alpha is Shape as required. This may affect anti-aliasing. (Do not turn it on, unless you really need it.)
Turn on or off Text Knockout.
If Text Knockout is enabled, the inks of underlying objects, if any, will be cut out on the other separations. This option may be useful in case of overlapping characters.
