This article demonstrates how to replace selected text in a Word document with an image using Spire.Doc for Java.
import com.spire.doc.Document;
import com.spire.doc.FileFormat;
import com.spire.doc.documents.TextSelection;
import com.spire.doc.fields.DocPicture;
import com.spire.doc.fields.TextRange;
public class ReplaceTextWithImage {
public static void main(String[] args) {
//Load a sample Word file
Document document = new Document();
document.loadFromFile("C:\\Users\\Administrator\\Desktop\\input.docx");
//Find the string 'E-iceblue' in the document
TextSelection[] selections = document.findAllString("E-iceblue", true, true);
//Replace the string with an image
int index = 0;
TextRange range = null;
for (Object obj : selections) {
TextSelection textSelection = (TextSelection)obj;
DocPicture pic = new DocPicture(document);
pic.loadImage("C:\\Users\\Administrator\\Desktop\\e-iceblue-logo.png");
range = textSelection.getAsOneRange();
index = range.getOwnerParagraph().getChildObjects().indexOf(range);
range.getOwnerParagraph().getChildObjects().insert(index,pic);
range.getOwnerParagraph().getChildObjects().remove(range);
}
//Save the document
document.saveToFile("output/ReplaceTextWithImage.docx", FileFormat.Docx_2013);
}

A trendline is a line superimposed on a chart revealing the overall direction of the data. Spire.Presentation for Java supports adding six different types of trendlines to chart, i.e. linear, logarithmic, polynomial, power, exponential and moving average.
The below example demonstrates how to use Spire.Presentation for Java to add a linear trendline to a chart.
import com.spire.presentation.FileFormat;
import com.spire.presentation.ISlide;
import com.spire.presentation.Presentation;
import com.spire.presentation.charts.IChart;
import com.spire.presentation.charts.ITrendlines;
import com.spire.presentation.charts.TrendlineSimpleType;
public class AddTrendlineToChart {
public static void main(String[] args) throws Exception {
//create a Presentation instance
Presentation ppt = new Presentation();
//load the PowerPoint document
ppt.loadFromFile("Chart.pptx");
//get the first slide
ISlide slide = ppt.getSlides().get(0);
//get the chart on the slide
IChart chart = (IChart)slide.getShapes().get(0);
//add a linear trendline to the first series of the chart
ITrendlines trendLine = chart.getSeries().get(0).addTrendLine(TrendlineSimpleType.LINEAR);
//display equation
trendLine.setdisplayEquation(true);
//save the resultant document
ppt.saveToFile("AddTrendline.pptx", FileFormat.PPTX_2013);
}
}

Java protect presentation slides by setting the property with mark as final
2019-11-19 08:25:39 Written by KoohjiMark as Final means that the presentation slide is final edition and the author doesn’t want any changes on the document. With Spire.Presentation for Java, we can protect the presentation slides by setting the password. This article demonstrates how to mark a presentation as final by setting the document property MarkAsFinal as true.
import com.spire.presentation.FileFormat;
import com.spire.presentation.Presentation;
public class MarkAsFinal {
public static void main(String[] args) throws Exception {
//Create a PPT document and load file
Presentation presentation = new Presentation();
presentation.loadFromFile("Sample.pptx");
//Set the document property MarkAsFinal as true
presentation.getDocumentProperty().set("_MarkAsFinal", true);
//Save the document to file
presentation.saveToFile("output/MarkasFinal.pptx", FileFormat.PPTX_2010);
}
}
