Hi All,
I am trying to translate the SVG content when I do the ZoomOut. So I have
calculated the translation value from the ZoomedOut transform. But when I
set this value in rendering transform, the translation is not happening
properly. Please see the following values.
AffineTransform rat = getRenderingTransform();
AffineTransform at = AffineTransform.getScaleInstance(scale, scale);
AffineTransform t = new AffineTransform(at);
t.concatenate(rat);
Rectangle r2d1 = rat.createTransformedShape(getViewBoxRect()).getBounds();
----(1)
Rectangle r2d2 = t.createTransformedShape(getViewBoxRect()).getBounds();
----(2)
if(r2d1.x < 0) {
double tx=Math.abs(r2d1.x)-Math.abs(r2d2.x);
double ty=Math.abs(r2d1.y)-Math.abs(r2d2.y);
t = AffineTransform.getTranslateInstance(tx, ty);
t.preConcatenate(at);
t.concatenate(rat);
}
setRenderingTransform(t);
----(3)
1 - java.awt.Rectangle[x=-4067,y=-2592,width=4792,height=3171]
2 - java.awt.Rectangle[x=-3661,y=-2333,width=4313,height=2854]
3 - AffineTransform[[3.75952335247409, 0.0, -3294.9], [0.0,
3.75952335247409, -2099.7000000000003]]
In the above values, my expected tx and ty supposed to be -3661 and -2333.
But my rendering transform is -3294.9 and 2099.7. So can anyone please
explain, how to calculate the correct translation value?
Thanks in advance.
Regards,
Selva
