XZOOM(6D)XZOOM(6D)NAMExzoom - magnify or minify an image in the x direction
SYNOPSISxzoom inimage outimage xscale yscale [-i -b -t -m or -q] [-w blurfactor]
DESCRIPTIONxzoom magnifies or minifies an image in the x direction with or without
filtering (xscale and yscale are floating point values). The filtering
method is one pass, uses 1-d convolution, and is optimized by integer
arithmetic and precomputation of filter coefficients. Normally xzoom
uses a triangle filter kernel in the x direction. The -i (impulse)
option causes xzoom to do no filtering as the image is resized. The -b
(box) option causes xzoom to use a box as the filter kernel. The -t
(triangle) option is the default. The -m (mitchell) option uses a cubic
filter kernel. The -q (quadratic) indicates that a quadradic function
should be used as the filter kernel.
