com.tlcsdm.core.javafx.util.ImgToolUtil

public class ImgToolUtil
extends Object

图片处理

 new Img("pic/1.jpg").thumbnail(100,100).save("pic/1_thumb.jpg");
 new Img("pic/1.jpg").resize(100,100).save("pic/1_scale.jpg");
 new Img("pic/1.jpg").corner(1.0f).save("pic/1_corner.jpg");//0~1.0f，1.0相当于变成圆形
 new Img("pic/1.jpg").square().save("pic/1_square.jpg");
 new Img("pic/1.jpg").rotate(45).save("pic/1_rotate.jpg");
 new Img("pic/1.jpg").draw("pic/logo.jpg").save("pic/1_logo.jpg");
 new Img("img/2.jpg").corner(1.0f).thumbnail(50, 50).save("img/2_50.jpg").corner().save("img/2_50_round.jpg");
