.SH NAME
vtkxform \- Apply coordinate transformation to point coordinates in VTK file.
.SH SYNOPSIS
\fBvtkxform\fR XformList 
.SH DESCRIPTION
An ASCII-format VTK file is read from standard input and a user-provided coordinate transformation (optionally inverted) is applied to the vertex coordinates.  A VTK file with transformed points is then written to standard output.
.SH OPTIONS
.SS Global Toolkit Options (these are shared by all CMTK tools)
.TP 5
\fB\-\-help\fR
Write list of basic command line options to standard output.
.TP 5
\fB\-\-help-all\fR
Write complete list of basic and advanced command line options to standard output.
.TP 5
\fB\-\-wiki\fR
Write list of command line options to standard output in MediaWiki markup.
.TP 5
\fB\-\-man\fR
Write man page source in 'nroff' markup to standard output.
.TP 5
\fB\-\-version\fR
Write toolkit version to standard output.
.TP 5
\fB\-\-echo\fR
Write the current command line to standard output.
.TP 5
\fB\-\-verbose-level\fR \fI<integer>\fR
Set verbosity level.
.TP 5
\fB\-\-verbose\fR, \fB\-v\fR
Increment verbosity level by 1 (deprecated; supported for backward compatibility).
.TP 5
\fB\-\-threads\fR \fI<integer>\fR
Set maximum number of parallel threads (for POSIX threads and OpenMP).
.SS Main Options
.TP 5
\fB\-\-inversion-tolerance\fR \fI<double>\fR
Numerical tolerance of B-spline inversion in mm. Smaller values will lead to more accurate inversion, but may increase failure rate.
.B [Default: 0.001]
.TP 5
\fB\-\-source-image\fR \fI<string>\fR
Set source image of the transformation (i.e., the image that the transformation maps points FROM) to correct for differences in orientation and coordinate space.
.B [Default: NONE]
.TP 5
\fB\-\-target-image\fR \fI<string>\fR
Set target image of the transformation (i.e., the image that the transformation maps points TO) to correct for differences in orientation and coordinate space.
.B [Default: NONE]
