Use the Resize dialog to change image size (width and height, in pixels) and resolution (dots per inch). The resolution is used to determines the size of a printed image. Changing the image size means changing the pixel dimensions of the image and resizing the image to fit those new dimensions. Decreasing the image size will decrease the memory requirements and possibly the file size of an image, but will also decrease the amount of detail in the image. Three methods for resizing the image are available: “Normal” (no interpolation), “Resample” (bilinear interpolation) and “Bicubic” (bicubic interpolation). Each method produces a resulting resized image of different quality. Bicubic resizing produces the highest quality image, whereas normal resizing is the fastest.
