java图片处理 - TwelveMonkeys ImageIO

javax.imageio原生支持的格式很少，特殊格式使用 ImageIO.read 获取的为null

可以用getWriterFileSuffixes()查询支持格式

String[] writerFileSuffixes = ImageIO.getWriterFileSuffixes();

原生支持格式

jpg,bmp,gif,png,jpeg,wbmp

TwelveMonkeys ImageIO 是对于 javax.imageio.*包 扩展的插件，这个插件配置后可以添加JRE本身没有覆盖的格式

tga图片转jpg

try {
            BufferedImage bufferegImage = ImageIO.read(new File("E:\\input.tga"));
            ImageIO.write(bufferegImage, "png", new File("E:output.jpg"));
        }catch (Exception e){
            System.out.println(e.getMessage());
