Modify Text in a Word Document in Java
To retrieve the paragraph from a particular section, you can use the Section.getParagraphs().get() method. Once you have the target paragraph, you can then update its text content by calling the Paragraph.setText() method and passing in the new text you want to assign.
The following are the steps modify text in a Word document using Java:
- Create a Document object.
- Load a Word file from the given file path.
- Get a specific section using Document.getSections().get() method.
- Get a specific paragraph using Section.getParagraphs().get() method.
- Reset the text of the paragraph using Paragraph.setText() method.
- Save the updated 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;
public class ModifyText {
https://ok.166.net/reunionpub/2023-06-06/ntesgod_cms/1686032662375_vfdeuv.png
public static void main(String[] args) {
// Create a new document object
Document document = new Document();
// Load an existing Word file
document.loadFromFile("C:\\Users\\Administrator\\Desktop\\input.docx");
// Get a specific section
Section section = document.getSections().get(0);
// Get a specific paragraph
Paragraph paragraph = section.getParagraphs().get(0);
// Modify the text of the paragraph
paragraph.setText("The title has been modified");
// Save the document to a different Word file
document.saveToFile("ModifyText.docx", FileFormat.Docx);
// Dispose resource
document.dispose();
}
}
Change Formatting of Text in a Word Document in Java
To modify the formatting of specific text within a paragraph, you first need to access the target paragraph object. Once you have the paragraph, you can then iterate through its child elements to locate the individual text ranges.
For each text range found, you can update the formatting by using the methods under the CharacterFormat object. This allows you to set properties like font name, size, color, and other text-level formatting options for the selected text.
The steps to change text formatting in a Word document are as follows:
- Create a Document object.
- Load a Word file from the given file path.
- Get a specific section using Document.getSections().get() method.
- Get a specific paragraph using Section.getParagraphs().get() method.
- Iterate through the child objects in the paragraph.
- Determine if a child object is a text range.
- Get a specific text range.
- Reset the text formatting using the methods under the CharacterFormat object.
- Save the updated 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.TextRange;
import java.awt.*;
public class ChangeTextFormatting {
public static void main(String[] args) {
// Create a new document object
Document document = new Document();
// Load an existing Word file
document.loadFromFile("C:\\Users\\Administrator\\Desktop\\input.docx");
// Get a specific section
Section section = document.getSections().get(0);
// Get a specific paragraph
Paragraph paragraph = section.getParagraphs().get(1);
// Iterate through the child objects in the paragraph
for (int i = 0; i < paragraph.getChildObjects().getCount(); i++)
{
// Determine if a child object is text range
if (paragraph.getChildObjects().get(i) instanceof TextRange)
{
// Get a specific text range
TextRange textRange = (TextRange)paragraph.getChildObjects().get(i);
// Reset font name for it
textRange.getCharacterFormat().setFontName("Corbel Light");
// Reset font size for it
textRange.getCharacterFormat().setFontSize(11);
// Reset text color for it
textRange.getCharacterFormat().setTextColor(Color.blue);
// Apply italic to the text range
textRange.getCharacterFormat().setItalic(true);
}
}
// Save the document to a different Word file
document.saveToFile("ChangeFont.docx", FileFormat.Docx);
// Dispose resource
document.dispose();
}
}
Add New Elements to a Word Document in Java
When working with Word documents, the paragraph serves as the foundational unit for incorporating diverse elements like text, images, lists, and charts. To introduce a new paragraph within a specific section, you can leverage the Section.addParagraph() method.
Once the paragraph has been added, you can then proceed to add various other elements to it by utilizing the methods available within the Paragraph object.
The following are the steps to add new elements (text and images) to a Word document using Java:
- Create a Document object.
- Load a Word file from the given file path.
- Get a specific section using Document.getSections() method.
- Add a paragraph to the section using Section.addParagraph() method.
- Add text to the paragraph using Paragraph.appendText() method.
- Add an image to the paragraph using Paragraph.appendPicture() method.
- Save the updated 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.documents.ParagraphStyle;
public class AddNewElements {
public static void main(String[] args) {
// Create a new document object
Document document = new Document();
// Load an existing Word file
document.loadFromFile("C:\\Users\\Administrator\\Desktop\\input.docx");
// Get the last section
Section lastSection = document.getLastSection();
// Add a paragraph to the section
Paragraph paragraph = lastSection.addParagraph();
// Add text to the paragraph
paragraph.appendText("This text and the image shown below are added programmatically using Spire.Doc for Java.");
// Add an image to the paragraph
paragraph.appendPicture("C:\\Users\\Administrator\\Desktop\\logo.png");
// Create a paragraph style
ParagraphStyle style = new ParagraphStyle(document);
style.setName("FontStyle");
style.getCharacterFormat().setFontName("Times New Roman");
style.getCharacterFormat().setFontSize(12);
document.getStyles().add(style);
// Apply the style to the paragraph
paragraph.applyStyle(style.getName());
// Save the document to a different Word file
document.saveToFile("AddNewElements.docx", FileFormat.Docx);
// Dispose resource
document.dispose();
}
}
Remove Paragraphs from a Word Document in Java
To remove a specific paragraph from the collection of paragraphs within a document, you can call the ParagraphCollection.removeAt() method. This method takes the index of the paragraph you wish to remove as an argument, allowing you to selectively delete the desired paragraph from the document.
The steps to remove paragraphs from a Word document using Java are as follows:
- Create a Document object.
- Load a Word file from the given file path.
- Get a specific section using Document.getSections().get() method.
- Remove a specific paragraph from the section using ParagraphCollection.removeAt() method.
- Save the updated document to a different Word file.
- Java
import com.spire.doc.Document;
import com.spire.doc.FileFormat;
import com.spire.doc.Section;
public class RemoveParagraph {
public static void main(String[] args) {
// Create a new document object
Document document = new Document();
// Load an existing Word file
document.loadFromFile("C:\\Users\\Administrator\\Desktop\\input.docx");
// Get a specific section
Section section = document.getSections().get(0);
// Remove a specific paragraph
section.getParagraphs().removeAt(0);
// Save the document to a different Word file
document.saveToFile("RemoveParagraph.docx", FileFormat.Docx);
// Dispose resource
document.dispose();

Insert Shapes in PowerPoint in Python
Spire.Presentation for Python enables you to add various types of shapes such as rectangles, circles, triangles, arrows, and eclipses to a PowerPoint slide by using the ISlide.Shapes.AppendShape() method.
Here are the steps to insert shapes in PowerPoint using Spire.Presentation for Python:
- Create an object of the Presentation class.
- Load a PowerPoint presentation using Presentation.LoadFromFile() method.
- Get a specific slide in the presentation using Presentation.Slides[index] property.
- Add various types of shapes to the slide using ISlide.Shapes.AppendShape() method and then set styles for the shapes.
- Save the resulting presentation using Presentation.SaveToFile() method.
- Python
from spire.presentation import *
# Create an object of the Presentation class
ppt = Presentation()
# Get the first slide
slide = ppt.Slides[0]
# Add a triangle shape to the slide
shape = slide.Shapes.AppendShape(ShapeType.Triangle, RectangleF.FromLTRB (115, 130, 215, 230))
shape.Fill.FillType = FillFormatType.Solid
shape.Fill.SolidColor.Color = Color.get_LightGreen()
shape.ShapeStyle.LineColor.Color = Color.get_White()
# Add an ellipse shape to the slide
shape = slide.Shapes.AppendShape(ShapeType.Ellipse, RectangleF.FromLTRB (290, 130, 440, 230))
shape.Fill.FillType = FillFormatType.Solid
shape.Fill.SolidColor.Color = Color.get_LightSkyBlue()
shape.ShapeStyle.LineColor.Color = Color.get_White()
# Add a heart shape to the slide
shape = slide.Shapes.AppendShape(ShapeType.Heart, RectangleF.FromLTRB (470, 130, 600, 230))
shape.Fill.FillType = FillFormatType.Solid
shape.Fill.SolidColor.Color = Color.get_Red()
shape.ShapeStyle.LineColor.Color = Color.get_LightGray()
# Add a five-pointed star shape to the slide
shape = slide.Shapes.AppendShape(ShapeType.FivePointedStar, RectangleF.FromLTRB (90, 270, 240, 420))
shape.Fill.FillType = FillFormatType.Gradient
shape.Fill.SolidColor.Color = Color.get_Black()
shape.ShapeStyle.LineColor.Color = Color.get_White()
# Add a rectangle shape to the slide
shape = slide.Shapes.AppendShape(ShapeType.Rectangle, RectangleF.FromLTRB (320, 290, 420, 410))
shape.Fill.FillType = FillFormatType.Solid
shape.Fill.SolidColor.Color = Color.get_Pink()
shape.ShapeStyle.LineColor.Color = Color.get_LightGray()
# Add an arrow shape to the slide
shape = slide.Shapes.AppendShape(ShapeType.BentUpArrow, RectangleF.FromLTRB (470, 300, 580, 400))
shape.Fill.FillType = FillFormatType.Gradient
shape.Fill.Gradient.GradientStops.AppendByKnownColors(1, KnownColors.Olive)
shape.Fill.Gradient.GradientStops.AppendByKnownColors(0, KnownColors.PowderBlue)
shape.ShapeStyle.LineColor.Color = Color.get_Red()
# Save the resulting presentation to a new file
ppt.SaveToFile("InsertShapes.pptx", FileFormat.Pptx2010)
ppt.Dispose()
Rotate Shapes in PowerPoint in Python
The IShape.Rotation property in Spire.Presentation for Python is used to rotate a shape on a PowerPoint slide. Setting this property to a positive value will rotate the shape clockwise, while setting it to a negative value will rotate the shape counterclockwise.
Here are the steps to rotate a shape in PowerPoint using Spire.Presentation for Python:
- Create an object of the Presentation class.
- Load a PowerPoint presentation using Presentation.LoadFromFile() method.
- Get a specific slide in the presentation using Presentation.Slides[index] property.
- Get a specific shape on the slide using ISlide.Shapes[index] property.
- Rotate the shape by specific degrees using IShape.Rotation property.
- Save the resulting presentation using Presentation.SaveToFile() method.
- Python
from spire.presentation import *
# Create an object of the Presentation class
ppt = Presentation()
# Load a PowerPoint presentation
ppt.LoadFromFile("ShapeTemplate1.pptx")
# Get the first slide
slide = ppt.Slides[0]
# Get the first shape on the slide
shape = slide.Shapes[0] if isinstance(slide.Shapes[0], IAutoShape) else None
# Rotate the shape 180 degrees clockwise
shape.Rotation = 180
# Save the resulting presentation to a new file
ppt.SaveToFile("RotateShape.pptx", FileFormat.Pptx2016)
ppt.Dispose()
Resize and Reposition Shapes in PowerPoint in Python
The size and position of a shape can be reset through the IShape.Height, IShape.Width and IShape.Left, IShape.Top properties.
Here are the steps to reset the size and position of shapes in PowerPoint using Spire.Presentation for Python:
- Create an object of the Presentation class.
- Load a PowerPoint presentation using Presentation.LoadFromFile() method.
- Get the original slide height and width using Presentation.SlideSize.Size.Height and Presentation.SlideSize.Size.Width properties.
- Change the slide size using Presentation.SlideSize.Type property, and then get the new slide height and width.
- Calculate the ratio for resetting the size and position of the shapes based on the original and new slide heights and widths.
- Iterate through the slides in the presentation and the shapes on each slide.
- Reset the size and position of each shape based on the specified ratio using IShape.Height, IShape.Width, IShape.Left and IShape.Top properties.
- Save the resulting presentation using Presentation.SaveToFile() method.
- Python
from spire.presentation import *
# Create an object of the Presentation class
ppt = Presentation()
# Load a PowerPoint presentation
ppt.LoadFromFile("ShapeTemplate.pptx")
# Get the original slide height and width
currentHeight = ppt.SlideSize.Size.Height
currentWidth = ppt.SlideSize.Size.Width
# Change the slide size to A3
ppt.SlideSize.Type = SlideSizeType.A3
# Get the new slide height and width
newHeight = ppt.SlideSize.Size.Height
newWidth = ppt.SlideSize.Size.Width
# Calculate the ratio for resizing shapes based on the original and new slide heights and widths
ratioHeight = newHeight / currentHeight
ratioWidth = newWidth / currentWidth
# Iterate through the slides in the presentation
for slide in ppt.Slides:
# Iterate through the shapes on the slide
for shape in slide.Shapes:
if isinstance(shape, IAutoShape):
# Reset the size of the shape based on the specified ratio
shape.Height = shape.Height * ratioHeight
shape.Width = shape.Width * ratioWidth
# Reset the position (x and y coordinates) of the shape based on the specified ratio
shape.Top = shape.Top * ratioHeight
shape.Left = shape.Left * ratioWidth
# Save the resulting presentation to a new file
ppt.SaveToFile("ResizeAndRepositionShapes.pptx", FileFormat.Pptx2016)
ppt.Dispose()
Reorder Shapes in PowerPoint in Python
The order in which shapes are arranged determines which shapes appear in front of or behind others. Using the ISlide.Shapes.ZOrder() method, you can easily change the order of multiple overlapping shapes on a PowerPoint slide.
Here are the steps to change the order of shapes in PowerPoint using Spire.Presentation for Python:
- Create an object of the Presentation class.
- Load a PowerPoint presentation using Presentation.LoadFromFile() method.
- Get a specific slide in the presentation using Presentation.Slides[index] property.
- Get a specific shape on the slide using ISlide.Shapes[index] property.
- Change the stacking order of the shape using ISlide.Shapes.ZOrder() method.
- Save the resulting presentation using Presentation.SaveToFile() method.
- Python
from spire.presentation import *
# Create an object of the Presentation class
ppt = Presentation()
# Load a PowerPoint presentation
ppt.LoadFromFile("ShapeTemplate3.pptx")
# Get the first slide
slide = ppt.Slides[0]
# Get the first shape on the slide
shape = slide.Shapes[0] if isinstance(slide.Shapes[0], IAutoShape) else None
# Change the stacking order of the shape
slide.Shapes.ZOrder(1, shape)
# Save the resulting presentation to a new file
ppt.SaveToFile("ReorderShapes.pptx", FileFormat.Pptx2016)
ppt.Dispose()
