Document Summary
Only be single image rotate cw scale (followed by a number to show the size of the image) flip horizontal image width > output is the number, showing the number of the dots lining in width image height > output is the number, showing the number of the dots lining in height crop top > followed by an image and then the number. Can be two or more images above > combine several images into one by putting in vertical direction beside > combine several images into one by putting in horizontal direction. * indirectly > number as the output from another function, such as we use the output from the function of image height. The input following the function term string append can be just the strings, just the definition terms, or the combination of them them i. e. (string append hello, hadifa period)
