This article demonstrates how to get the position of text in PowerPoint in Java using Spire.Presentation for Java.

import com.spire.presentation.IAutoShape;
import com.spire.presentation.ISlide;
import com.spire.presentation.Presentation;

import java.awt.geom.Point2D;

public class GetPositionOfText {
    public static void main(String []args) throws Exception {
        //Create a Presentation instance
        Presentation ppt = new Presentation();
        //Load a PowerPoint document
        ppt.loadFromFile("Sample.pptx");

        //Get the first slide
        ISlide slide = ppt.getSlides().get(0);
        //Get the first shape
        IAutoShape shape = (IAutoShape)slide.getShapes().get(0);
        //Get location of text in the shape
        Point2D location =shape.getTextFrame().getTextLocation();

        //Print out the x and y coordinates of the location relative to slide
        String  point1="Text's position relative to Slide: x= "+location.getX()+" y = "+location.getY();
        System.out.println(point1);

        //Print out the x and y coordinates of the location relative to shape
        String point2 = "Text's position relative to shape: x= " + (location.getX() - shape.getLeft()) + "  y = " + (location.getY() - shape.getTop());
        System.out.println(point2);
    }
}

Output:

This article demonstrates how to apply transparency to text in PowerPoint using Spire.Presentation for Java.

import com.spire.presentation.*;
import com.spire.presentation.drawing.FillFormatType;

import java.awt.*;
import java.awt.geom.Rectangle2D;

public class ApplyTransparency {

    public static void main(String[] args) throws Exception {

        //Create a PowerPoint document
        Presentation presentation = new Presentation();
        presentation.getSlideSize().setType(SlideSizeType.SCREEN_16_X_9);

        //Add a shape
        IAutoShape textbox = presentation .getSlides().get(0).getShapes().appendShape(ShapeType.RECTANGLE,new Rectangle2D.Float(50, 70, 300, 120));
        textbox.getShapeStyle().getLineColor().setColor(new Color(1,1,1,0));
        textbox.getFill().setFillType(FillFormatType.NONE);

        //Remove default paragraphs
        textbox.getTextFrame().getParagraphs().clear();

        //Add three paragraphs and apply colors with different alpha values to the text
        int alpha = 55;
        for (int i = 0; i < 3; i++)
