文本形狀的圖像裁剪我需要在另一個圖像中剪出一個文本形狀的圖像。我認為最好用圖片來展示。文本圖像將始終是黑色的透明背景，并由此產生的剪除也應該有一個透明的背景。兩個輸入圖像也將是相同的大小。

public static BufferedImage textEffect(BufferedImage image, BufferedImage text) {
if (image.getWidth() != text.getWidth() ||
image.getHeight() != text.getHeight())
{
throw new IllegalArgumentException("Dimensions are not the same!");
}
BufferedImage img = new BufferedImage(image.getWidth(),
image.getHeight(),
BufferedImage.TYPE_INT_ARGB_PRE);
for (int y = 0; y < image.getHeight(); ++y) {
for (int x = 0; x < image.getWidth(); ++x) {
int textPixel = text.getRGB(x, y);
int textAlpha = (textPixel & 0xFF000000);
int sourceRGB = image.getRGB(x, y);
int newAlpha = (int) (((textAlpha >> 24) * (sourceRGB >> 24)) / 255d);
int imgPixel = (newAlpha << 24) | (sourceRGB & 0x00FFFFFF);
int rgb = imgPixel | textAlpha;
img.setRGB(x, y, rgb);
}
}
return img;}
