Object Opacity
PTC Arbortext Layout Developer provides the option to specify the opacity of certain objects when creating PDF output. You can set objects such as watermarks to be transparent, so they are visible through other objects.
Opacity is specified as a percentage – 100% represents full color output, and 0% represents no color.
These formatting objects can be given an opacity setting, when they are defined with JavaScript/FOM:
• Frames
• Styles
• Rules
• Named colors
• Accolades (inline and via control stream)
• Inline graphics
There is no option to define opacity in the PTC Arbortext Layout Developer UI.
There are some limitations to the support in this release:
• Opacity settings are respected in PDF output. They are not reflected in WYSIWYG view of an object.
• Opacity is not fully supported for U3D or PDF graphics.
FOM Objects Supporting this Feature
These formatting objects carry a property opacity, which accepts a percentage as a value:
• fFrame
• fStyle
• fRule
• fNamedColor
• fAccolade
• fAccoladeInline
The fFormatting.addImage() method has a parameter opacity, which also accepts a percentage as a value. This parameter allows the setting of opacity to inline graphics.
