Abstract
A method for enlarging a binary image by an arbitrary factor includes the steps of storing the image in bit sequence; rotating the image in a first direction by ninety degrees; inserting one or more rows of expansion bits along the original horizontal axis of the image to convert i rows of bits to j rows of bits where i<j<=2i; assigning a value to each expansion bit generated by the above step; repeating the steps of inserting and assigning a predetermined number of times to achieve an enlargement by a factor F1 along said original horizontal axis; rotating the image in a second direction opposite said first direction by ninety degrees; inserting one or more rows of expansion bits along the vertical axis of the image to convert i rows of bits to j rows of bits where i<j<=2i; assigning a value to each expansion bit generated by the above step; repeating the steps of inserting and assigning a predetermined number of times to achieve an enlargement by a factor F2 along said vertical axis; storing the enlarged image generated by the above steps.
