Apologies if I have overlooked something: is there a way to get the length in twips or points of the text that is held in an XWPFParagraph. I could achieve it using Font And FontMetrics separately but that seems clunky. Any help will be much appreciated.
i I've searched what I hoped were the relevant Apache Javadocs.
While calculating text length using font metrics may seem a bit cumbersome, it's a common approach across various libraries and frameworks. However, if you're looking for a potentially less clunky method within Apache POI specifically, you might consider using the Graphics2D class from AWT (Abstract Window Toolkit) for font metrics. Here's the implementation in a simplified example:
import org.apache.poi.xwpf.usermodel.*;
import java.awt.*;
import java.awt.font.FontRenderContext;
import java.awt.geom.AffineTransform;
public class ParagraphLength {
public static void main(String[] args) {
XWPFDocument doc = new XWPFDocument(); // Your XWPFDocument instance
XWPFParagraph paragraph = doc.createParagraph(); // Your XWPFParagraph instance
// Set your text here
String text = "Your text goes here";
paragraph.createRun().setText(text);
int fontSize = 12; // Change this to match your font size
int twips = getTextLengthTwips(paragraph, fontSize);
System.out.println("Text length in twips: " + twips);
float points = twips / 20f; // 1 twip = 1/20 point
System.out.println("Text length in points: " + points);
}
public static int getTextLengthTwips(XWPFParagraph paragraph, int fontSize) {
Graphics2D graphics2D = (Graphics2D) new BufferedImage(1, 1, BufferedImage.TYPE_INT_ARGB).getGraphics();
Font font = new Font("Arial", Font.PLAIN, fontSize);
graphics2D.setFont(font);
FontMetrics fontMetrics = graphics2D.getFontMetrics();
int totalWidth = 0;
for (XWPFRun run : paragraph.getRuns()) {
totalWidth += fontMetrics.stringWidth(run.text());
}
return totalWidth * 20; // Convert pixels to twips
}
}
While it may not significantly reduce the clunkiness, it abstracts away some of the direct font manipulation and calculation, making the code slightly cleaner.
