<page>
elementThe <page>
tag has the optional attributes gridsize
,
section
, and subsection
. The gridsize
indicates
the last grid size used on this page--Ipe remembers this as it is
often advantageous to have the same grid available that was used when
making the page. The value of section
and subsection
is
the title of a section starting on this page. If the attribute is not
present, this page continues the section of the previous page.
The contents of the <page>
element consists, in this order, of
possibly empty sequences of <layer>
elements, <view>
elements, and Ipe object elements.
The <layer>
tag takes a required attribute name
, and two
optional attributes visible
and edit
. The name
has to be unique within the page. The value of visible
should
be yes
, no
, or dim
, and indicates how the layer
is displayed on the screen (not in the PDF output--this is
determined by the <view>
elements), the value of edit
should be yes
or no
and indicates whether the user can
select and modify the contents of the layer in the Ipe user interface
(of course the user can always modify the setting of the attribute).
The layer element must be empty.
If a page contains no layer element, Ipe automatically adds a default layer named "alpha", visible and editable.
The <view>
tag takes a required attribute layers
, and
three optional attributes, duration
, transition
, and
effect
. The value of layers
must be a sequence of layer
names defined in this page, separated by white space. The value of
duration
and transition
must be a real number, the value
of effect
must be an integer between 0 and 16 (see
IpeView::TEffect
for the exact meaning of those). The
parameters translated directly into the page transition effect in PDF.
It is okay for a page not to contain any <view>
element. Such a
page will be saved to PDF including all its layers, with no special
effect.
The remaining elements of the <page>
are Ipe objects.
