Instance Method Summary collapse
-
#add_dest(name, reference) ⇒ Object
Adds a new destination to the dests name tree (see #dests).
-
#dest_fit(dest_page = page) ⇒ Object
Return a Dest specification that will fit the given page into the viewport.
-
#dest_fit_bounds(dest_page = page) ⇒ Object
Return a Dest specfication that will fit the given page’s bounding box into the viewport.
-
#dest_fit_bounds_horizontally(top, dest_page = page) ⇒ Object
Same as #dest_fit_horizontally, but works on the page’s bounding box instead of the entire page.
-
#dest_fit_bounds_vertically(left, dest_page = page) ⇒ Object
Same as #dest_fit_vertically, but works on the page’s bounding box instead of the entire page.
-
#dest_fit_horizontally(top, dest_page = page) ⇒ Object
Return a Dest specification that will fit the given page horizontally into the viewport, aligned vertically at the given top coordinate.
-
#dest_fit_rect(left, bottom, right, top, dest_page = page) ⇒ Object
Return a Dest specification that will fit the given rectangle into the viewport, for the given page.
-
#dest_fit_vertically(left, dest_page = page) ⇒ Object
Return a Dest specification that will fit the given page vertically into the viewport, aligned horizontally at the given left coordinate.
-
#dest_xyz(left, top, zoom = nil, dest_page = page) ⇒ Object
Return a Dest specification for a specific location (and optional zoom level).
-
#dests ⇒ Object
The Dests name tree in the Name dictionary (see Prawn::Document::Internal#names).
Instance Method Details
#add_dest(name, reference) ⇒ Object
Adds a new destination to the dests name tree (see #dests). The reference
parameter will be converted into a PDF::Core::Reference if it is not already one.
