Rotating BufferedImage changes its colors

Question

I\'m trying to code a class to seam carve images in x and y direction. The x direction is working, and to reduce the y direction I thought about simply rotating the image 90

Answer 1

It seems like there's a color conversion happening due to passing null to op.filter(imgIn2, null);.

If you change it like that it should work:

BufferedImage last = new BufferedImage( imgIn2.getWidth(), imgIn2.getHeight(), imgIn2.getType() );
op.filter(imgIn2, last );
