I want to rotate an image about the z axis using java.
I tried to search for ways to do that but it involves complex matrix manipulations and it works on 3d models and stuff. I will resort to that if there is no other way but would like to know if there are any other alternatives for this.
I simply need to rotate an image about z axis and nothing else.
This is what I need exactly:
I have an image like this:
And I want to convert it to something of this sort:
I did this using processing. I need some way of doing this using java.
Best How To :
If you are referring to rotating an image during a Swing
paint operation, then the correct way to do this is with an
AffineTransform does not support perspective transforms (by definition a transform is only Affine if parallel lines remain parallel). For perspective transforms you need to use the Java Advanced Imaging API which can be downloaded from Oracle's site. It has a
PerspectiveTransform that does just what you want. Unfortunately JAI is not quite as straightforward to use as it is much more flexible.
