Yes thomas. there is the problem in my code in finding transform value. I
have tried to find the tranlation value using available size and scaled
size. But still i couldn't resolve my problem in finding transform. So can
you please suggest me that where i am doing mistake. Please find the
following code so that you can find the problem easily.
AffineTransform rat = getRenderingTransform();
AffineTransform at = null;
if (_zoomInflag) {
at = AffineTransform.getScaleInstance(1.1, 1.1);
}
else if (_zoomOutflag) {
at = AffineTransform.getScaleInstance(.9, .9);
}
else {
return;
}
AffineTransform t1 = new AffineTransform(at);
t1.concatenate(rat);
AffineTransform vbt = getViewBoxTransform();
Rectangle2D viewBox = getViewBoxRect();
Rectangle originalSize = vbt.createTransformedShape(viewBox).getBounds();
Rectangle changedSize = t1.createTransformedShape(viewBox).getBounds();
int tx = 0, ty = 0;
tx = originalSize.x - changedSize.x;
ty = originalSize.y - changedSize.y;
t1.preConcatenate(AffineTransform.getTranslateInstance( -tx, -ty));
setRenderingTransform(t1);
Thanks in advance.
Regards,
Selva
