常用示例
Shear image horizontally
pnmshear [30] [input.pnm] > [output.pnm]
Shear with background color
pnmshear -background [white] [45] [input.pnm] > [output.pnm]
说明
pnmshear applies a horizontal shear transformation to PNM images, sliding each row by an amount proportional to its distance from the center. The result is a parallelogram-shaped image where the shear angle is specified in degrees. Anti-aliasing is applied by default for smooth results. The -background option sets the fill color for newly exposed areas, and -noantialias disables smoothing. Part of the Netpbm toolkit.
