Page assembly

Page timeout interval

The typesetting engine will force an error exit if any individual page is not assembled within the page assembly timeout interval. The default timeout interval is 180 seconds. You may need to increase the timeout interval if your TopLeaf stylesheet processes a large number of mappings, for example if your style sheet loads a included Xref table before rendering the content of the first page.

Page output layering order

Each page generated by TopLeaf may contain any or all of the following components:

  • Filled regions;

  • Images;

  • Ruled lines;

  • Text characters.

When TopLeaf is requested to print or create a PDF for a page, these components are processed in a fixed order. Text characters will always be rendered last, so they will appear on top of other content.
