Resize Methods

Fixed Width - height is automatically resized with the same ratio with the width
Fixed Height - width is automatically resized with the same ratio as the height
Scale - the image is scaled so that the width OR height is adjusted correctly for the new dimensions and both axis are scaled similarly. It is then centre cropped.
Stretch - each dimension is stretched independently to the new size, without trying to keep the same ratio
Letterbox - the image is scaled so that each dimension keeps the same ratio, but any areas which are not taken are filled with the background color. You do not lose any image to a crop.
Percentage - the image is scaled in both dimensions at this ratio
