示例1: isJFIFcompliant
import javax.imageio.ImageTypeSpecifier; //导入方法依赖的package包/类
/**
* Returns <code>true</code> if the given imageType can be used
* in a JFIF file. If <code>input</code> is true, then the
* image type is considered before colorspace conversion.
*/

boolean input) {
ColorModel cm = imageType.getColorModel();
// Can't have alpha
if (cm.hasAlpha()) {
