Coordinate System in PDF

When using Spire.PDF for Python to modify a PDF document, the coordinate system's origin is at the top-left corner of the page. The x-axis extends to the right, while the y-axis extends downward.

Page numbers are usually positioned in the header or footer. Thus, it's important to consider the page size and margins when determining the placement of the page numbers.

Classes and Methods for Creating Page Numbers

Spire.PDF for Python provides the PdfPageNumberField and PdfPageCountField classes to retrieve the current page number and total page count. These can be merged into a single PdfCompositeField that formats the output as "Page X of Y", where X represents the current page number and Y indicates the total number of pages.

To position the PdfCompositeField on the page, use the Location property, and render it with the Draw() method.

Add Left-Aligned Page Numbers to PDF Footer

To add left-aligned page numbers in the footer, you need to consider the left and bottom page margins as well as the page height. For example, you can use coordinates such as (LeftMargin, PageHeight – BottomMargin + SmallNumber). This ensures that the page numbers align with the left side of the text while keeping a comfortable distance from both the content and the edges of the page.

The steps to add left-aligned page numbers to PDF footer are as follows:

• Create a PdfDocument object.
• Load a PDF file from a specified path.
• Create a PdfPageNumberField object and a PdfPageCountField object.
• Create a PdfCompositeField object to combine page count field and page number field in a single string.
• Set the position of the composite field through PdfCompositeField.Location property to ensure the page number aligns with the left side of the text.
• Iterate through the pages in the document, and draw the composite field on each page at the specified location.
• Save the document to a different PDF file.

from spire.pdf.common import *
from spire.pdf import *

# Create a PdfDocument object
doc = PdfDocument()

# Load a PDF file
doc.LoadFromFile("C:\\Users\\Administrator\\Desktop\\Privacy Policy.pdf")

# Create font, brush and pen
font = PdfTrueTypeFont("Times New Roman", 12.0, PdfFontStyle.Regular, True)
brush = PdfBrushes.get_Black()
pen = PdfPen(brush, 1.0)

# Create a PdfPageNumberField object and a PdfPageCountField object
pageNumberField = PdfPageNumberField()
pageCountField = PdfPageCountField()

# Create a PdfCompositeField object to combine page count field and page number field in a single string
compositeField = PdfCompositeField(font, brush, "Page {0} of {1}", [pageNumberField, pageCountField])

# Get the page size
pageSize = doc.Pages[0].Size

# Specify the blank areas around the page
leftMargin = 54.0
rightMargin = 54.0
bottomMargin = 72.0

# Set the location of the composite field
compositeField.Location = PointF(leftMargin, pageSize.Height - bottomMargin + 18.0)

# Iterate through the pages in the document
for i in range(doc.Pages.Count):

    # Get a specific page
    page = doc.Pages[i]

    # Draw a line at the specified position
    page.Canvas.DrawLine(pen, leftMargin, pageSize.Height - bottomMargin + 15.0, pageSize.Width - rightMargin, pageSize.Height - bottomMargin + 15.0)

    # Draw the composite field on the page
    compositeField.Draw(page.Canvas, 0.0, 0.0)

# Save to a different PDF file
doc.SaveToFile("Output/LeftAlignedPageNumbers.pdf")

# Dispose resources
doc.Dispose()

Add Center-Aligned Page Numbers to PDF Footer

To position the page number in the center of the footer, you first need to measure the width of the page number itself. Once you have this measurement, you can calculate the appropriate X coordinate by using the formula (PageWidth - PageNumberWidth) / 2. This ensures the page number is horizontally centered within the footer.

The steps to add center-aligned page numbers to PDF footer are as follows:

• Create a PdfDocument object.
• Load a PDF file from a specified path.
• Create a PdfPageNumberField object and a PdfPageCountField object.
• Create a PdfCompositeField object to combine page count field and page number field in a single string.
• Set the position of the composite field through PdfCompositeField.Location property to ensure the page number is perfectly centered in the footer.
• Iterate through the pages in the document, and draw the composite field on each page at the specified location.
• Save the document to a different PDF file.

from spire.pdf.common import *
from spire.pdf import *

# Create a PdfDocument object
doc = PdfDocument()

# Load a PDF file

# Create font, brush and pen
font = PdfTrueTypeFont("Times New Roman", 12.0, PdfFontStyle.Regular, True)
brush = PdfBrushes.get_Black()
pen = PdfPen(brush, 1.0)

# Specify the blank margins around the page
leftMargin = 54.0
rightMargin = 54.0
bottomMargin = 72.0

# Create a PdfPageNumberField object and a PdfPageCountField object
pageNumberField = PdfPageNumberField()
pageCountField = PdfPageCountField()

# Create a PdfCompositeField object to combine page count field and page number field in a single field
compositeField = PdfCompositeField(font, brush, "Page {0} of {1}", [pageNumberField, pageCountField])

# Iterate through the pages in the document
for i in range(doc.Pages.Count):

    # Get a specific page
    page = doc.Pages[i]

    # Get the page size
    pageSize = doc.Pages[i].Size

    # Draw a line at the specified position
    page.Canvas.DrawLine(pen, leftMargin, pageSize.Height - bottomMargin + 15.0, pageSize.Width - rightMargin, pageSize.Height - bottomMargin + 15.0)

    # Measure the size the "Page X of Y"
    pageNumberSize = font.MeasureString("Page {} of {}".format(i + 1, doc.Pages.Count))

    # Set the location of the composite field
    compositeField.Location = PointF((pageSize.Width - pageNumberSize.Width)/2, pageSize.Height - bottomMargin + 18.0)

    # Draw the composite field on the page
    compositeField.Draw(page.Canvas, 0.0, 0.0)

# Save to a different PDF file
doc.SaveToFile("Output/CenterAlignedPageNumbers.pdf")

# Dispose resources
doc.Dispose()

Add Right-Aligned Page Numbers to PDF Footer

To add a right-aligned page number in the footer, measure the width of the page number. Then, calculate the X coordinate using the formula PageWidth - PageNumberWidth - RightMargin. This ensures that the page number aligns with the right side of the text.

The following are the steps to add right-aligned page numbers to PDF footer:

• Create a PdfDocument object.
• Load a PDF file from a specified path.
• Create a PdfPageNumberField object and a PdfPageCountField object.
• Create a PdfCompositeField object to combine page count field and page number field in a single string.
• Set the position of the composite field through PdfCompositeField.Location property to ensure the page number aligns with the right side of the text.
• Iterate through the pages in the document, and draw the composite field on each page at the specified location.
• Save the document to a different PDF file.

Background Knowledge

Spire.PDF for Python offers the PdfPageTemplateElement class for defining page template elements. It provides users with PdfPageTemplateElement.Graphics.DrawString()， PdfPageTemplateElement.Graphics.DrawLine()， PdfPageTemplateElement.Graphics.DrawImage(), and more to draw text, lines, and images. Furthermore, Spire.PDF for Python supports drawing automatic fields like PdfPageCountField and PdfPageNumberField to the template element by PdfGraphicsWidget.Draw() method.

To draw content on the PdfPageTemplateElement template element, the coordinate system settings are as follows:

• The coordinates system's origin is positioned at the top left corner of the template.
• The x-axis extends to the right, and the y-axis extends downward.

Spire.PDF for Python provides PdfDocumentTemplate class to design the entire page templates of a PDF. The defined PdfPageTemplateElement page template elements above can be applied to the PdfDocumentTemplate page template directly.

PdfDocumentTemplate can apply one or more PdfPageTemplateElement page template elements. For example, apply them to PdfDocumentTemplate.Top and PdfDocumentTemplate.Bottom page templates to create a header and footer in the PDF.

The new page generated by Spire.PDF contains margins by default. The initialization coordinates for the PdfDocumentTemplate page template are set as follows:

Content cannot be drawn in the margins. To apply PdfPageTemplateElement to PdfDocumentTemplate for the header and footer, you can reset the PDF margins to 0. This way, the coordinate system of the PdfDocumentTemplate page template on the new page will adjust based on the size set by the PdfPageTemplateElement. For example:

Add Footer to an Existing PDF Document in Python

A footer refers to a section that appears at the bottom of each page. The footer may contain information such as page numbers, copyright information, author name, date, or any other relevant details that provide additional context or navigation aids to the reader.

To add a footer which includes a line and "Page X of Y" to a PDF document, follow the steps below.

• Create a PdfDocuemnt object.
• Load an existing PDF document from the specified path.
• Define the footer content: Create a PdfPageNumberField object to get the current page number, and a PdfPageCountField object to get the total page count. In order to create a "Page X of Y" format, you can utilize a PdfCompositeField object to combine text and these two automatic fields in a single field.
• Add the footer to each page: Iterate through each page of the PDF document and add a line using the Canvas.DrawLine() method. Add the page number and page count to the footer space using the PdfCompositeField.Draw() method. When calling these methods, you need to consider the page size and margins when determining the position.
• Save the modified PDF to a new file or overwrite the existing file.

from spire.pdf.common import *
