在另一个图像下旋转一个图像 [英] Rotating one image under another one

问题描述

我目前正在尝试旋转图像，然后在顶部绘制一个不旋转的图像。但每当我使用：
g2d.rotate（Math.toRadians（rot），（x + 15），（y + 15））;
我之后绘制的每个图像也会旋转。有什么方法可以旋转一个图像而不是旋转其余的图像（这真的很难解释）。
这是我的绘画方法：

I am currently trying to rotate an image and then drawing an image on top which isn't rotating. But whenever I use: g2d.rotate(Math.toRadians(rot), (x+15), (y+15)); every image I draw afterwards rotates as well. Is there any way I can rotate one image and not rotate the rest (gosh its really hard to explain). Here's my paint method:

public void draw(Graphics2D g2d)
{
    move();
    if(bo.px==+1)rot--;
    if(bo.px==-1)rot++;
    g2d.rotate(Math.toRadians(rot), (x+15), (y+15));
    g2d.drawImage(img, x, y, null);//this should rotate
    g2d.drawImage(shine, x, y, null);//this shouldn't
}

提前致谢。

推荐答案

您可以保存原始变换，旋转并绘制第一个图像，然后在绘制第二个图像之前应用原始变换。

You can save the original transform, rotate and draw the first image and then apply back the original transform before drawing the second image.

尝试

AffineTransform originalTransform = g2d.getTransform();
g2d.rotate(Math.toRadians(rot), (x+15), (y+15));
g2d.drawImage(img, x, y, null);
g2d.setTransform(originalTransform);
g2d.drawImage(shine, x, y, null);
