问题:给定两个图像,一个包含文本,另一个包含图像,创建图像的形状的剪裁文本。
要求:
解决方案:
要实现这个效果,我们可以使用Java AWT库。下面是演示如何操作的代码片段:
import java.awt.*; import java.awt.font.*; import java.awt.image.BufferedImage; import java.awt.geom.Rectangle2D; import javax.imageio.ImageIO; import java.net.URL; import java.io.File; class PictureText { public static void main(String[] args) throws Exception { URL imageUrl = new URL("https://i.sstatic.net/Nqf3H.jpg"); BufferedImage originalImage = ImageIO.read(imageUrl); BufferedImage textImage = new BufferedImage( originalImage.getWidth(), originalImage.getHeight(), BufferedImage.TYPE_INT_ARGB); Graphics2D g = textImage.createGraphics(); FontRenderContext frc = g.getFontRenderContext(); Font font = new Font(Font.SANS_SERIF, Font.BOLD, 250); GlyphVector gv = font.createGlyphVector(frc, "Cat"); Rectangle2D box = gv.getVisualBounds(); int xOffset = 25 + (int)-box.getX(); int yOffset = 80 + (int)-box.getY(); Shape shape = gv.getOutline(xOffset, yOffset); g.setClip(shape); g.drawImage(originalImage, 0, 0, null); g.setClip(null); g.setStroke(new BasicStroke(2f)); g.setColor(Color.BLACK); g.setRenderingHint( RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON); g.draw(shape); g.dispose(); File outputFile = new File("cat-text.png"); ImageIO.write(textImage, "png", outputFile); Desktop.getDesktop().open(outputFile); } }
在此代码中:
