  2. Create a Graph Object
  3. Add Graph object to paragraphs collection of page.
  4. Create and Configure the Line
  5. Add the Line to the Graph
  6. Save our PDF file.
import aspose.pdf as ap
import aspose.pdf.drawing as drawing


def add_line(outfile: str):
    document = ap.Document()
    page = document.pages.add()
    graph = drawing.Graph(100, 400)
    page.paragraphs.add(graph)

    line = drawing.Line([100, 100, 200, 100])
    line.graph_info.dash_array = [0, 1, 0]
    line.graph_info.dash_phase = 1
    graph.shapes.add(line)

    document.save(outfile)

How to add Dotted Dashed Line to your PDF document

import aspose.pdf.drawing as drawing

def add_dotted_dashed_line(outfile: str):
    document = ap.Document()
    page = document.pages.add()
    graph = drawing.Graph(100, 400)
    page.paragraphs.add(graph)

    line = drawing.Line([100, 100, 200, 100])
    line.graph_info.color = ap.Color.red
    line.graph_info.dash_array = [0, 1, 0]
    line.graph_info.dash_phase = 1
    graph.shapes.add(line)

Draw Line Across the Page

You can also draw lines across the page to form a cross.

import aspose.pdf as ap
import aspose.pdf.drawing as drawing

def draw_line_across_page(outfile: str):
    document = ap.Document()
    page = document.pages.add()
    page.page_info.margin.left = 0
    page.page_info.margin.right = 0
    page.page_info.margin.bottom = 0
    page.page_info.margin.top = 0

    graph = drawing.Graph(page.page_info.width, page.page_info.height)
    line = drawing.Line([page.rect.llx, 0, page.page_info.width, page.rect.ury])
    graph.shapes.add(line)
    line2 = drawing.Line([0, page.rect.ury, page.page_info.width, page.rect.llx])
    graph.shapes.add(line2)
    page.paragraphs.add(graph)

    document.save(outfile)
