Thanks Chris. This article helped me greatly. I have added a blur before the do while loop. To me, then, the quality is very very close to a photoshop resize. I guess its in the eye of the beholder. if (higherQuality) { // Setup blur convolve before resizing float weight = 1.0f/9.0f; float[] elements = new float[9]; for (int i = 0; i < 9; i++) { elements[i] = weight; } Kernel blurKernel = new Kernel(3, 3, elements); ConvolveOp blur = new ConvolveOp(blurKernel); tmp = new BufferedImage(w, h, type); blur.filter(ret, tmp); ret = tmp; }
