HI,
I am performing the rotate operation on planarimage.my code to rotate the
image is:
private PlanarImage rotateImage(RenderedImage image){
ParameterBlock pg = new ParameterBlock();
float y = (float)image.getHeight()/2;
float x = (float)image.getWidth()/2;
float angle = (float)Math.toRadians(90);
pg.addSource(image);
pg.add(x);
pg.add(y);
pg.add(angle);
pg.add(Interpolation.getInstance(Interpolation.INTERP_NEAREST));
return JAI.create("rotate",pg);
}
the resulting planarimage is null.nothing is diaplayed on canvas.when i am
printing the properties of the resulting planarimage it show me height is 0
ans widht is 0.
i can't understand why it give me null image.
what is wrong in my code???can anyone suggest the right way to do the
rotation through JAI.
Regards,
Sonal.
