Create New Document - DocumentCreation

The following sample illustrates how to use the Layout::FlowDocument API to create documents from scratch. Instead of positioning every element on a page, the content is described as a tree of paragraphs, tables, lists, shapes, charts, and floats, which is then paginated into a PDF document. \

Each function below produces a document:

• An invoice: Tables, cell merging, styling, headers/footers, images.

• A report: Sections, page setup, lists, charts, page numbers.

• A newsletter: Shapes, shape text boxes, floats, hyperlinks, tab stops.

• A content tree walk: Post-processing of an existing content tree.

// to programmatically create rich PDF documents.
//
// Instead of placing every element on a page, the content is described as a tree of
// paragraphs, tables, lists, shapes, charts and floats, which is then paginated into
// a PDF document.
//
// Each function below produces one document:
//   * an invoice          - tables, cell merging, styling, headers/footers, images
//   * a report            - sections, page setup, lists, charts, page numbers
//   * a newsletter        - shapes, shape text boxes, floats, hyperlinks, tab stops
//   * a content tree walk - post-processing of an existing content tree
//
// The documents are generated entirely within PDFNet with no external or system
// dependencies, enabling consistent results across platforms.
//
// Please contact us if you have any questions.

# from scratch. Instead of positioning every element on a page, the content is described
# as a tree of paragraphs, tables, lists, shapes, charts and floats, which is then
# paginated into a PDF document.
#
# Each function below produces one document:
#   * an invoice          - tables, cell merging, styling, headers/footers, images
#   * a report            - sections, page setup, lists, charts, page numbers
#   * a newsletter        - shapes, shape text boxes, floats, hyperlinks, tab stops
#   * a content tree walk - post-processing of an existing content tree

// as a tree of paragraphs, tables, lists, shapes, charts and floats, which is then
// paginated into a PDF document.
//
// Each function below produces one document:
//   * an invoice          - tables, cell merging, styling, headers/footers, images
//   * a report            - sections, page setup, lists, charts, page numbers
//   * a newsletter        - shapes, shape text boxes, floats, hyperlinks, tab stops
//   * a content tree walk - post-processing of an existing content tree
//
// Note: the Layout::List and Layout::Float classes are exposed as ListContainer and
// FloatContainer, because "list" and "float" are reserved names in PHP.

# from scratch. Instead of positioning every element on a page, the content is described
# as a tree of paragraphs, tables, lists, shapes, charts and floats, which is then
# paginated into a PDF document.
#
# Each function below produces one document:
#   * an invoice          - tables, cell merging, styling, headers/footers, images
#   * a report            - sections, page setup, lists, charts, page numbers
#   * a newsletter        - shapes, shape text boxes, floats, hyperlinks, tab stops
#   * a content tree walk - post-processing of an existing content tree
#
# Note: the Layout::Float class is exposed as FloatContainer, because Ruby's core Float
# class shadows it once the PDFNetRuby module is included.
