class Tioga::Transparency

These are the attributes for using transparency in PDF graphics. The transparency is speficied by a fraction, with 1.0 for fully transparent and 0.0 for fully opaque. Since transparency can also be thought of in terms of opacity, there are accessors defined in those terms also. Thus, for example, setting #fill_opacity to 0.2 is equivalent to setting #fill_transparency to 0.8.

Public Instance Methods

fill_opacity click to toggle source

fill_opacity = a_float

Defines the opacity to use for fill and other non-stroke graphics operations including images. Valid values are between 1.0 (fully opaque) to 0.0 (fully transparent). Default is 1.0 (opaque).

Example: on left, #fill_opacity = 1.0; on right #fill_opacity = 0.6

# File lib/Tioga/Transparency.rb, line 36
def fill_opacity
end

fill_transparency = a_float

Defines the transparency to use for fill and other non-stroke graphics operations including images. Valid values are between 0.0 (fully opaque) to 1.0 (fully transparent). Default is 0.0 (opaque).

Example: on left, #fill_transparency = 0.0; on right #fill_transparency = 0.4
