The IlvPrintableLayout Class

IlvPrintableLayout is an abstract class that is the base class for describing page layouts. It defines a usable area by specifying left, right, top, bottom, and gutter margins.

It defines five subareas within the usable area and associates them with printables:

• The main area that will be used to print the main printable.

You can choose to stretch the printable to the usable area or to keep the printable aspect ratio.

• The header area that will be used to print a header printable.

• The footer area that will be used to print a footer printable.

• The background area that will be printed behind the main area.

• The foreground area that will be printed in front of the main area.

The dimensions of the header and footer areas can be specified.

Predefined layouts are:

• IlvPrintableLayoutOnePage lays out the printable on one page. This layout uses a single page to render the printable.

• IlvPrintableLayoutMultiplePages lays out the printable on an array of pages. The dimension of the pages matrix is user specified.

This layout defines a virtual page that spans through the multiple pages. The header area is defined at the top of the virtual page, the footer area at the bottom of the virtual page.

• IlvPrintableLayoutIdentity allows the printed document to be the same size as the printable.

This layout inherits from IlvPrintableLayoutMultiplePages and uses whatever number of pages are necessary.

• IlvPrintableLayoutFixedSize allows you to choose the printed document size.

This layout inherits from IlvPrintableLayoutMultiplePages and uses whatever number of pages are necessary.
