Antenna House Formatter V7.3

Spread Page Master Extension no-LT

Antenna House Formatter V7.3 is able to treat two facing pages (a two-page spread) as a single unit, and you can define spread regions that span across the two pages. You can also define a single background for the two pages.

The requirement for formatting facing pages as a two-page spread appears in:

Only some documents need spreads, but uses for spreads include:

  • Titles that extend across two pages
  • Graphics or tables that are wider than one page
  • Full-bleed background images that extend across two pages

The Spread Page Master Extension adds the following two Formatting Objects:

FODefinition
<axf:spread-page-master>Defines the spread.
<axf:spread-region>Region that can span two pages.

Two-page spreads are typically exceptions to normal formatting, so <axf:spread-page-master> refers to other page masters for the definitions of the two pages' sizes and non-spread regions. When an <axf:spread-region> intersects an <fo:region-body> from one of the page masters, the <fo:region-body> is resized to be a smaller, rectangular region. When an <axf:spread-region> covers an <fo:region-body> from one of the page masters, the <fo:region-body> is dropped from the spread.

Extended Elements

<axf:spread-page-master> no-LT XSL-FO Samples CollectionSpread page masterTable across two pages

Common Usage:

Specifies a two-page spread.

<axf:spread-page-master> is used in page master selection in the same way as <fo:simple-page-master>, but it always causes a multiple of two pages to be generated. You must ensure that the pairs of pages occur as two-page spreads. Properties that can help enforce this are maximum-repeats, initial-page-number, and force-page-count.

If the <axf:spread-region> children generate all regions on the pages (for example, the spread pages are a multi-page, double-wide table) but you do not know how many pairs of pages the spread content will use generate, then either the <axf:spread-page-master> should be the last page master in the <fo:page-sequence-master> or the content of the spread pages should be in a nested <fo:page-sequence> that uses only the <axf:spread-page-master>.

Areas:

Generates no area directly. It is used in the generation of pages by an <fo:page-sequence>.

Constraints:

<axf:spread-region> no-LT XSL-FO Samples CollectionSpread page master

Common Usage:

Specifies a region in a two-page spread.

Areas:

Used to generate one region-viewport-area and one region-reference-area whenever its parent <axf:spread-page-master> is used to generate a page.

Extended Properties

axf:left-page-master-reference no-LT

Master name of the page master for the left page of a two-page spread.

Value:<name>
Initial:N/A, a value is required
Applies to:axf:spread-page-master
Inherited:no
Percentages:N/A

Values have the following meanings:

<name>

The name must refer to a master-name that exists within the document.

axf:left-page-master-reference refers to the page master that defines the page size and the non-spread regions for the left-hand page of a two-page spread.

axf:right-page-master-reference no-LT

Master name of the page master for the right page of a two-page spread.

Value:<name>
Initial:N/A, a value is required
Applies to:axf:spread-page-master
Inherited:no
Percentages:N/A

Values have the following meanings:

<name>

The name must refer to a master-name that exists within the document.

axf:right-page-master-reference refers to the page master that defines the page size and the non-spread regions for the right-hand page of a two-page spread.

Example

The following example shows two pages generated using an <axf:spread-page-master>. The definitions of the page sizes and non-spread regions are from the “left” and “right” <fo:simple-page-master> that are referred to from the “spreadpm” <axf:spread-page-master>. The <axf:spread-page-master> defines a “top” <axf:spread-region> that spans across the two pages of the spread. In this example, the “top” region contains a title. The content of the “xsl-region-body” flow generates areas in the body regions defined by the <fo:region-body> in the two <fo:page-sequence-master>.
