Get PDF Page Size in C#
Spire.PDF for .NET offers the PdfPageBase.Size.Width and PdfPageBase.Size.Height properties to get the width and height of a PDF page in points. If you want to convert the default unit of measure to other units, you can use the PdfUnitConvertor class. The following are the detailed steps.
- Create a PdfDocument instance.
- Load a PDF file using PdfDocument.LoadFromFile() method.
- Get a specified page using PdfDocument.Pages[] property.
- Get the width and height of the PDF page using PdfPageBase.Size.Width and PdfPageBase.Size.Height properties.
- Create a PdfUnitConvertor instance, and then convert the size units from points to other units of measure using PdfUnitConvertor.ConvertUnits() method.
- Add the page size information to a StringBuilder instance, and then save the result to a TXT file.
- C#
using System.Text;
using Spire.Pdf;
using Spire.Pdf.Graphics;
namespace GetPDFPageSize
{
class Program
{
static void Main(string[] args)
{
//Create a PdfDocument object
PdfDocument pdf = new PdfDocument();
//Load a PDF file from disk
pdf.LoadFromFile("SamplePDF.pdf");
//Get the first page
PdfPageBase page = pdf.Pages[0];
//Get the width and height of the page in "point"
float pointWidth = page.Size.Width;
float pointHeight = page.Size.Height;
//Create PdfUnitConvertor to convert the unit
PdfUnitConvertor unitCvtr = new PdfUnitConvertor();
//Convert size units from points to pixels
float pixelWidth = unitCvtr.ConvertUnits(pointWidth, PdfGraphicsUnit.Point, PdfGraphicsUnit.Pixel);
float pixelHeight = unitCvtr.ConvertUnits(pointHeight, PdfGraphicsUnit.Point, PdfGraphicsUnit.Pixel);
//Convert size units from points to inches
float inchWidth = unitCvtr.ConvertUnits(pointWidth, PdfGraphicsUnit.Point, PdfGraphicsUnit.Inch);
float inchHeight = unitCvtr.ConvertUnits(pointHeight, PdfGraphicsUnit.Point, PdfGraphicsUnit.Inch);
//Convert size units from points to centimeters
float centimeterWidth = unitCvtr.ConvertUnits(pointWidth, PdfGraphicsUnit.Point, PdfGraphicsUnit.Centimeter);
float centimeterHeight = unitCvtr.ConvertUnits(pointHeight, PdfGraphicsUnit.Point, PdfGraphicsUnit.Centimeter);
//Create a StringBuilder instance
StringBuilder content = new StringBuilder();
//Add the page size information to the StringBuilder instance
content.AppendLine("The page size of the file in points is (width: " + pointWidth + "pt, height: " + pointHeight + "pt).");
content.AppendLine("The page size of the file in pixels is (width: " + pixelWidth + "pixel, height: " + pixelHeight + "pixel).");
content.AppendLine("The page size of the file in inches is (width: " + inchWidth + "inch, height: " + inchHeight + "inch).");
content.AppendLine("The page size of the file in centimeters is (width: " + centimeterWidth + "cm, height: " + centimeterHeight + "cm).");
//Save to a txt file
File.WriteAllText("GetPageSize.txt", content.ToString());
}
}
}
Detect PDF Page Orientation in C#
To detect the orientation of a PDF page, you can compare the width and height of the page. If the page width is greater than the height, then the page orientation is landscape, otherwise it is portrait. The following are the detailed steps.
- Create a PdfDocument instance.
- Load a PDF file using PdfDocument.LoadFromFile() method.
- Get a specified page using PdfDocument.Pages[] property.
- Get the width and height of the PDF page using PdfPageBase.Size.Width and PdfPageBase.Size.Height properties.
- Compare the values of page width and height to detect the page orientation.
- Output the result using Console.WriteLine() method.
- C#
using Spire.Pdf;
namespace GetPDFPageOrientation
{
class Program
{
static void Main(string[] args)
{
//Create a PdfDocument object
PdfDocument pdf = new PdfDocument();
//Load a PDF file from disk
pdf.LoadFromFile("SamplePDF.pdf");
//Get the first page
PdfPageBase page = pdf.Pages[0];
//Get the width and height of the page
float width = page.Size.Width;
float height = page.Size.Height;
//Compare the values of page width and height
if (width > height)
{
Console.WriteLine("The page orientation is Landscape.");
}
else
{
Console.WriteLine("The page orientation is Portrait.");
}
}
}
}
Detect PDF Page Rotation Angle in C#
The rotation angle of a PDF page can be obtained through the PdfPageBase.Rotation property. The following are the detailed steps.
- Create a PdfDocument instance.
- Load a PDF file using PdfDocument.LoadFromFile() method.
- Get a specified page using PdfDocument.Pages[] property.
- Get the rotation angle of the page using PdfPageBase.Rotation property, and then convert it to text string.
- Output the result using Console.WriteLine() method.
- C#
using Spire.Pdf;
namespace GetPDFPageRotationAngle
{
class Program
{
static void Main(string[] args)
{
//Create a PdfDocument object
PdfDocument pdf = new PdfDocument();
//Load a PDF file from disk
pdf.LoadFromFile("E:\\PythonPDF\\Sample.pdf");
//Get the first page
PdfPageBase page = pdf.Pages[0];
//Get the rotation angle of the current page
PdfPageRotateAngle rotationAngle = page.Rotation;

Create a Clustered Column Chart in Word in Java
To insert a chart into a Microsoft Word document, you can use the Paragraph.appendChart(ChartType chartType, float width, float height) method. The ChartType enumeration provides various pre-defined chart types available in MS Word. To create a clustered column chart, you would specify the chart type as Column.
The steps to add a clustered column chart to a Word document using Java are as follows:
- Create a Document object.
- Add a section and a paragraph to the document.
- Add a clustered column chart to the paragraph using Paragraph.appendChart() method.
- Add series to the chart using Chart.getSeries().add() method.
- Set the chart title using Chart.getTilte().setText() method.
- Set other attributes of the chart using the methods available in the Chart object.
- Save the document to a different Word file.
- Java
import com.spire.doc.Document;
import com.spire.doc.FileFormat;
import com.spire.doc.Section;
import com.spire.doc.documents.Paragraph;
import com.spire.doc.fields.ShapeObject;
import com.spire.doc.fields.shapes.charts.*;
public class CreateClusteredColumnChart {
public static void main(String[] args) {
// Create a Document object
Document document = new Document();
// Add a section
Section section = document.addSection();
// Add a paragraph
Paragraph paragraph = section.addParagraph();
// Add a column chart
ShapeObject shape = paragraph.appendChart(ChartType.Column, 490, 250);
// Get the chart
Chart chart = shape.getChart();
// Clear the default data
chart.getSeries().clear();
// Add a series including series name, category names, and series values to chart
chart.getSeries().add("June",
new String[] { "Cuba", "Mexico", "France"},
new double[] { 5000, 8000, 9000 });
// Add two more series
chart.getSeries().add("July",
new String[] { "Cuba", "Mexico", "France"},
new double[] { 4000, 5000, 7000 });
chart.getSeries().add("August",
new String[] { "Cuba", "Mexico", "France"},
new double[] { 3500, 7000, 5000 });
// Set the chart title
chart.getTitle().setText("Sales by Country");
// Set the number format of the Y-axis
chart.getAxisY().getNumberFormat().setFormatCode("#,##0");
// Set the legend position
chart.getLegend().setPosition(LegendPosition.Bottom);
// Save to file
document.saveToFile("ClusteredColumnChart.docx", FileFormat.Docx_2019);
// Dispose resources
document.dispose();
}
}
Create a Stacked Column Chart in Word in Java
Creating a stacked column chart in a Word document follows a similar process to the clustered column chart. The only difference is specifying the chart type as Column_Stacked instead of Column.
The detailed steps to add a stacked column chart are:
- Create a Document object.
- Add a section and a paragraph to the document.
- Add a stacked column chart to the paragraph using Paragraph.appendChart() method.
- Add series to the chart using Chart.getSeries().add() method.
- Set the chart title using Chart.getTilte().setText() method.
- Set other attributes of the chart using the methods available in the Chart object.
- Save the document to a different Word file.
- Java
import com.spire.doc.Document;
import com.spire.doc.FileFormat;
import com.spire.doc.Section;
import com.spire.doc.documents.Paragraph;
import com.spire.doc.fields.ShapeObject;
import com.spire.doc.fields.shapes.charts.Chart;
import com.spire.doc.fields.shapes.charts.ChartType;
import com.spire.doc.fields.shapes.charts.LegendPosition;
public class CreateStackedColumnChart {
public static void main(String[] args) {
//Create a Document object
Document document = new Document();
//Add a section
Section section = document.addSection();
//Add a paragraph
Paragraph paragraph = section.addParagraph();
//Add a stacked column chart
ShapeObject shape = paragraph.appendChart(ChartType.Column_Stacked, 490, 250);
//Get the chart
Chart chart = shape.getChart();
//Clear the default data
chart.getSeries().clear();
//Add a series including series name, category names, and series values to chart
chart.getSeries().add("Store A",
new String[] { "Diet Coke", "Mountain Dew", "Diet Pesi", "Cherry Coke" },
new double[] { 2500, 4600, 2800, 5100 });
//Add another series
chart.getSeries().add("Store B",
new String[] { "Diet Coke", "Mountain Dew", "Diet Pesi", "Cherry Coke" },
new double[] { 4100, 3200, 3800, 4000 });
//Set the chart title
chart.getTitle().setText("Store Wise Soda Soft Drink Sales");
//Set the number format of the Y-axis
chart.getAxisY().getNumberFormat().setFormatCode("#,##0");
//Set the legend position
chart.getLegend().setPosition(LegendPosition.Bottom);
//Save to file
document.saveToFile("StackedColumnChart.docx", FileFormat.Docx_2019);
// Dispose resources
document.dispose();

To add a text markup annotation to a PDF, you first need to locate the specific text within the document with the help of the PdfTextFinder class. Once the text is identified, you can create a PdfTextMarkupAnnotation object and apply it to the document.
The following are the steps to add a text markup annotation to PDF using Python:
- Create a PdfDocument object.
- Load a PDF file from the specified location.
- Get a page from the document.
- Find a specific piece of text within the page using PdfTextFinder class.
- Create a PdfTextMarkupAnnotation object based on the text found.
- Add the annotation to the page using PdfPageBase.AnnotationsWidget.Add() method.
- Save the modified document to a different PDF file.
- Python
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\\Input.pdf")
# Get a specific page
page = doc.Pages[0]
# Create a PdfTextFinder object based on the page
finder = PdfTextFinder(page)
# Set the find options
finder.Options.Parameter = TextFindParameter.WholeWord
finder.Options.Parameter = TextFindParameter.IgnoreCase
# Find the instances of the specified text
fragments = finder.Find("However, we cannot and do not guarantee that these measures will prevent "+
"every unauthorized attempt to access, use, or disclose your information since "+
"despite our efforts, no Internet and/or other electronic transmissions can be completely secure.");
# Get the first instance
textFragment = fragments[0]
# Specify annotation text
text = "Here is a markup annotation."
# Iterate through the text bounds
for i in range(len(textFragment.Bounds)):
# Get a specific bound
rect = textFragment.Bounds[i]
# Create a text markup annotation
annotation = PdfTextMarkupAnnotation("Administrator", text, rect)
# Set the markup color
annotation.TextMarkupColor = PdfRGBColor(Color.get_Green())
# Add the annotation to the collection of the annotations
page.AnnotationsWidget.Add(annotation)
# Save result to file
doc.SaveToFile("output/MarkupAnnotation.pdf")
# Dispose resources
doc.Dispose()
Add a Free Text Annotation to PDF in Python
Free text annotations allow adding freeform text comments directly on a PDF. To add a free text annotation at a specific location, you can use the PdfTextFinder class to obtain the coordinate information of the searched text, then create a PdfFreeTextAnnotation object based on that coordinates and add it to the document.
The following are the steps to add a free text annotation to PDF using Python:
- Create a PdfDocument object.
- Load a PDF file from the specified location.
- Get a page from the document.
- Find a specific piece of text within the page using PdfTextFinder class.
- Create a PdfFreeTextAnnotation object based on the coordinate information of the text found.
- Set the annotation content using PdfFreeTextAnnotation.Text property.
- Add the annotation to the page using PdfPageBase.AnnotationsWidget.Add() method.
- Save the modified document to a different PDF file.

page = doc.Pages[0]
# Create a PdfTextFinder object based on the page
finder = PdfTextFinder(page)
# Set the find options
finder.Options.Parameter = TextFindParameter.WholeWord
finder.Options.Parameter = TextFindParameter.IgnoreCase
# Find the instances of the specified text
fragments = finder.Find("Children");
# Get the first instance
textFragment = fragments[0]
# Get the text bound
rect = textFragment.Bounds[0]
# Get the coordinates to add annotation
right = bound.Right
top = bound.Top
# Create a free text annotation
rectangle = RectangleF(right + 5, top + 2, 160.0, 18.0)

# Set the content of the annotation
textAnnotation.Text = "Here is a free text annotation."
# Set other properties of annotation
font = PdfFont(PdfFontFamily.TimesRoman, 13.0, PdfFontStyle.Regular)
border = PdfAnnotationBorder(1.0)
textAnnotation.Font = font
textAnnotation.Border = border
textAnnotation.BorderColor = PdfRGBColor(Color.get_SkyBlue())
textAnnotation.Color = PdfRGBColor(Color.get_LightBlue())
textAnnotation.Opacity = 1.0
# Add the annotation to the collection of the annotations

Python: Remove Hyperlinks from PowerPoint Presentations
PowerPoint presentations often contain hyperlinks that guide audiences to additional resources or locations within the presentations. While these links can be useful for providing further information and easy navigation, there are instances where they may detract from the presentation's flow or compromise its professional appearance. Those invalid or unnecessary links in slides can be easily removed using Python, enhancing the overall quality of the presentations.
This article will show how Spire.Presentation for Python can be utilized to remove hyperlinks from PowerPoint presentations efficiently.
- Remove Hyperlinks from Text in PowerPoint Slides
- Remove Hyperlinks from All Shapes in PowerPoint Slides
- Remove Hyperlinks from Specific Types of Shapes in PowerPoint Slides
- Remove Hyperlinks from Table Text in PowerPoint Slides
Install Spire.Presentation for Python
This scenario requires Spire.Presentation for Python and plum-dispatch v1.7.4. They can be easily installed in your Windows through the following pip command.
pip install Spire.Presentation
If you are unsure how to install, please refer to: How to Install Spire.Presentation for Python on Windows
Remove Hyperlinks from Text in PowerPoint Slides
The normal text in a PowerPoint presentation is contained in auto shapes. Developers can access the text ranges within these shapes using the IAutoShape.TextFrame.Paragraphs[].TextRanges[] property and read or set the hyperlinks on them using the TextRange.ClickAction property. Hyperlinks on text can be removed by setting the TextRange.ClickAction property to None.
The detailed steps are as follows:
- Create an instance of Presentation class and load a PowerPoint presentation using Presentation.LoadFromFile() method.
- Iterate through the slides in the presentation and then iterate through the shapes in the slides.
- Check if the shape is an instance of IAutoShape. If it is, iterate through the paragraphs in the shape, and then the text ranges in the paragraphs.
- Check if the TextRange.ClickAction property of a text range is None. If it is not, remove the hyperlink by setting TextRange.ClickAction property to None.
- Save the presentation using Presentation.SaveToFile() method.
- Python
from spire.presentation import Presentation, IAutoShape, FileFormat
# Create an instance of Presentation
presentation = Presentation()
# Load a PowerPoint presentation
presentation.LoadFromFile("Sample.pptx")
# Iterate through the slides in the presentation
for slide in presentation.Slides:
# Iterate through the shapes
for shape in slide.Shapes:
# Check if the shape is an AutoShape instance
if isinstance(shape, IAutoShape):
# Iterate through the paragraphs in the shape
for paragraph in shape.TextFrame.Paragraphs:
# Iterate through the text ranges in the paragraph
for textRange in paragraph.TextRanges:
# Check if the text range has a hyperlink
if textRange.ClickAction is not None:
# Remove the hyperlink
textRange.ClickAction = None
# Save the presentation
presentation.SaveToFile("output/RemoveSlideTextHyperlink.pptx", FileFormat.Pptx2013)
presentation.Dispose()
Remove Hyperlinks from All Shapes in PowerPoint Slides
The IShape class represents all types of shapes in a presentation slide, such as auto shapes, images, tables, and more. The hyperlink on all these shapes can be removed by setting the value obtained from the IShape.Click.get_NoAction() method as the value of the shapes’ IShape.Click property. The detailed steps are as follows:
- Create an instance of Presentation class and load a PowerPoint presentation using Presentation.LoadFromFile() method.
- Iterate through the slides in the presentation and then iterate through the shapes in the slides.
- Check if the IShape.Click property is None. If it is not, remove the hyperlink by setting the property to the result of IShape.Click.get_NoAction() method.
- Save the presentation using Presentation.SaveToFile() method.
- Python
from spire.presentation import Presentation, FileFormat
# Create an instance of Presentation
presentation = Presentation()
# Load a PowerPoint presentation
presentation.LoadFromFile("Sample.pptx")
# Iterate through the slides in the presentation
for slide in presentation.Slides:
# Iterate through the shapes in the slide
for shape in slide.Shapes:
# Check if the shape has a hyperlink
if shape.Click is not None:
# Remove the click action
shape.Click = shape.Click.get_NoAction()
# Save the presentation
presentation.SaveToFile("output/RemoveSlideShapeHyperlink.pptx", FileFormat.Pptx2013)
presentation.Dispose()
Remove Hyperlinks from Specific Types of Shapes in PowerPoint Slides
In addition to directly removing hyperlinks for all shapes, we can also determine the shape type before removing the hyperlinks to find and remove hyperlinks from shapes of the specified type. The detailed steps are as follows:
- Create an instance of Presentation class and load a PowerPoint presentation using Presentation.LoadFromFile() method.
- Iterate through the slides in the presentation and then iterate through the shapes in the slides.
- Check if the shape is an instance of IEmbedImage, ITable, or IChart. If it is, check if the IShape.Click property of the shape is None. If it is not, remove the hyperlink by setting the property to the result of IShape.Click.get_NoAction() method.
- Save the presentation using Presentation.SaveToFile() method.
- Python
from spire.presentation import Presentation, FileFormat, IEmbedImage, ITable, IChart
# Create an instance of Presentation
presentation = Presentation()
# Load a PowerPoint presentation
presentation.LoadFromFile("Sample.pptx")
# Iterate through the slides in the presentation
for slide in presentation.Slides:
# Iterate through the shapes in the slide
for shape in slide.Shapes:
# Check if the shape is an embedded image
if isinstance(shape, (IEmbedImage, ITable, IChart)):
# check if the click action is not None
if shape.Click is not None:
# Remove the click action
shape.Click = shape.Click.get_NoAction()
# Save the presentation
presentation.SaveToFile("output/RemoveSlideShapeTypeHyperlink.pptx", FileFormat.Pptx2013)
presentation.Dispose()
Remove Hyperlinks from Table Text in PowerPoint Slides
To remove hyperlinks from text within a table, it is necessary to iterate through the table's cells and the text ranges within each cell. Afterward, the hyperlinks on the text ranges in each cell can be removed by setting the TextRange.ClickAction property to None. The detailed steps are as follows:
- Create an instance of Presentation class and load a PowerPoint presentation using Presentation.LoadFromFile() method.
- Iterate through the slides in the presentation and then iterate through the shapes in the slides.
- Check if a shape is an instance of ITable class. If it is, iterate through the rows in the table and then the cells in the rows.
- Iterate through the paragraphs in the cells and then the text ranges in the paragraphs.
- Check if the TextRange.ClickAction property of a text range is None. If it is not, remove the hyperlink by setting the value of the property to None.
- Save the presentation using Presentation.SaveToFile() method.
- Python
from spire.presentation import Presentation, ITable, FileFormat
# Create an instance of Presentation
presentation = Presentation()
# Load a PowerPoint presentation
presentation.LoadFromFile("Sample.pptx")
# Iterate through the slides in the presentation
for slide in presentation.Slides:
# Iterate through the shapes in the slide
for shape in slide.Shapes:
# Check if the shape is a table
if isinstance(shape, ITable):
# Get the table
table = ITable(shape)
# Iterate through the rows in the table
for row in table.TableRows:
# Iterate through the cells in the row
for cell in row:
# Iterate through the paragraphs in the cell
for para in cell.TextFrame.Paragraphs:
# Iterate through the text ranges in the paragraph
for range in para.TextRanges:
# Check if the text run contains a hyperlink
if range.ClickAction is not None:
# Remove the hyperlink
range.ClickAction = None
presentation.SaveToFile("output/RemoveSlideTableTextHyperlink.pptx", FileFormat.Pptx2013)
presentation.Dispose()
