vscale − scale graphical data in a VisionX file

vscale
if=infile of=outfile [x=<xval>] [y=<xval>] [z=<zval>] [-xz] [-yz] [-zz]
[-p]

Vscale Scales the bounding box and associated graphical data in a VisionX file by the amounts specified by the parameters. This is particularly useful for 3-D images when converting to a symbolic from a pixel domain since it permits the symbolic domain to be scaled to meaningful units. By default, all scale factors are assumed to be 1.0 and no scaling is performed.

x=<value>

Specifies the scale factor for the x direction (all x coordinates are multiplied by this amount.

y=<value>

Specifies the scale factor for the y direction.

z=<value>

Specifies the scale factor for the z direction.

-xz

translate the x axis to origin, that is the low x value in the bounding box will be set to zero.

-yz

translate the y axis to origin, that is the low y value in the bounding box will be set to zero.

-zz

translate the z axis to origin, that is the low z value in the bounding box will be set to zero.
