加载图像后，你可以尝试：
BufferedImage createResizedCopy(Image originalImage, int scaledWidth, int scaledHeight, boolean preserveAlpha) { System.out.println("resizing..."); int imageType = preserveAlpha ? BufferedImage.TYPE_INT_RGB : BufferedImage.TYPE_INT_ARGB; BufferedImage scaledBI = new BufferedImage(scaledWidth, scaledHeight, imageType); Graphics2D g = scaledBI.createGraphics(); if (preserveAlpha) { g.setComposite(AlphaComposite.Src); } g.drawImage(originalImage, 0, 0, scaledWidth, scaledHeight, null); g.dispose(); return scale
