For example, from the string Pritom K Mondal, I would like to generate this simple image: |
package com.pkm; import java.awt.Color; import java.awt.Font; import java.awt.FontMetrics; import java.awt.Graphics2D; import java.awt.RenderingHints; import java.awt.image.BufferedImage; import java.io.File; import java.io.IOException; import javax.imageio.ImageIO; public class TextToImage { public static void main(String[] args) { String text = "Pritom K Mondal"; BufferedImage img = new BufferedImage(1, 1, BufferedImage.TYPE_INT_ARGB); Graphics2D g2d = img.createGraphics(); Font font = new Font("Arial", Font.PLAIN, 48); g2d.setFont(font); FontMetrics fm = g2d.getFontMetrics(); int width = fm.stringWidth(text) + 20; int height = fm.getHeight(); g2d.dispose(); img = new BufferedImage(width, height, BufferedImage.TYPE_INT_ARGB); g2d = img.createGraphics(); g2d.setRenderingHint(RenderingHints.KEY_ALPHA_INTERPOLATION, RenderingHints.VALUE_ALPHA_INTERPOLATION_QUALITY); g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON); g2d.setRenderingHint(RenderingHints.KEY_COLOR_RENDERING, RenderingHints.VALUE_COLOR_RENDER_QUALITY); g2d.setRenderingHint(RenderingHints.KEY_DITHERING, RenderingHints.VALUE_DITHER_ENABLE); g2d.setRenderingHint(RenderingHints.KEY_FRACTIONALMETRICS, RenderingHints.VALUE_FRACTIONALMETRICS_ON); g2d.setRenderingHint(RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BILINEAR); g2d.setRenderingHint(RenderingHints.KEY_RENDERING, RenderingHints.VALUE_RENDER_QUALITY); g2d.setRenderingHint(RenderingHints.KEY_STROKE_CONTROL, RenderingHints.VALUE_STROKE_PURE); g2d.setFont(font); fm = g2d.getFontMetrics(); g2d.setColor(Color.BLACK); g2d.drawString(text, 10, fm.getAscent()); g2d.dispose(); try { ImageIO.write(img, "png", new File("Image.png")); } catch (IOException ex) { ex.printStackTrace(); } } } |
And output is like below: |
