Java处理某些图片红色问题(ImageIO.read()读取ICC)
imageIO.read 在读取图片的时候可能会不正确的读取图片的ICC信息,
所以当这种情况不能用ImageIO读取图片文件
使用java中自带jdk
ICC为JPEG图片格式中的一种头部信息,导致渲染图片前景色时蒙上一层红色。
Image src=Toolkit.getDefaultToolkit().getImage(file.getPath());
BufferedImage image=BufferedImageBuilder.toBufferedImage(src);
public static BufferedImage toBufferedImage(Image image) {
if (image instanceof BufferedImage) {
return (BufferedImage) image;
}
image = new ImageIcon(image).getImage();
BufferedImage bimage = null;
GraphicsEnvironment ge = GraphicsEnvironment
.getLocalGraphicsEnvironment();
try {
int transparency = Transparency.OPAQUE;
GraphicsDevice gs = ge.getDefaultScreenDevice();
GraphicsConfiguration gc = gs.getDefaultConfiguration();
bimage = gc.createCompatibleImage(image.getWidth(null),
image.getHeight(null), transparency);
} catch (HeadlessException e) {
}
if (bimage == null) {
int type = BufferedImage.TYPE_INT_RGB;
bimage = new BufferedImage(image.getWidth(null),
image.getHeight(null), type);
}
Graphics g = bimage.createGraphics();
g.drawImage(image, 0, 0, null);
g.dispose();
return bimage;
}
