Abstract
An oblique projection original is formed by deforming an orthogonal projection original in such a manner that a rectangular original is transformed into a trapezoidal original by compressing the orthogonal projection original by thinning scanning lines in a horizontal direction. In addition, predetermined bits in each scanning line are thinned in a vertical direction, and each line is compressed by reducing first and last portions of each line by half the number of bits thus thinned. Finally, white bits are inserted at the first and last portions of each scanning line to complete each scanning line.
