NAME

teem-ilk - (I)mage (L)inear Trans(X-->K)forms.

SYNOPSIS

teem-ilk [@file ...] [-i <image>] [-0 <origin>] \fR

DESCRIPTION

/usr/bin/teem-ilk: (I)mage (L)inear Trans(X-->K)forms. Applies linear (homogenous
coordinate) transforms to a given image, using the given kernel for resampling.

-t <xform0 ...> [-k <kernel>] [-min <xMin yMin>] [-max <xMax yMax>] \

[-b <boundary>] [-bg <bg0 bg1 ...>] [-s <xSize ySize>] [-a <avg #>] \ [-o
<filename>]

@file ... = response file(s) containing command-line arguments

-i <image> = input image; default: "-"

-0 <origin> = where to location (0,0) prior to applying transforms.
o "u:<float>,<float>" locate origin in a unit box [0,1]x[0,1] which covers the
original imago "p:<float>,<float>" locate origin at a particular pixel location, in
the index space of the image default: "p:0,0"

-t <xform0 ...> = transform(s) to apply to image. Transforms are applied in
the order in which they appear. o "identity": no geometric transform, just
resamplino "translate:x,y": shift image by vector (x,y), as measured in pixelso
"rotate:ang": rotate CCW by ang degreeo "scale:xs,ys": scale by xs in X, and ys in
o "shear:fix,amnt": shear by amnt, keeping fixed the pixels along a direction <fix>
degrees from the X axio "flip:ang": flip along axis an angle <ang> degrees from the
X axio "a,b,tx,c,d,ty": specify the transform explicitly in row-major order
(opposite of PostScript) (1 or more 2D transforms)

-k <kernel> = reconstruction kernel; default: "cubic:0,0.5"

-min <xMin yMin> = lower bounding corner of output image. Default (by not
using this option) is the lower corner of input image. (2 doubles)

-max <xMax yMax> = upper bounding corner of output image. Default (by not
using this option) is the upper corner of input image. (2 doubles)

-b <boundary> = what to do when sampling outside original image.
o "bleed": copy values at image border outwaro "wrap": do wrap-around on image
locationo "pad": use a given background value (via "-bg") default: "bleed"

-bg <bg0 bg1 ...> = background color to use with boundary behavior "pad".

Defaults to all zeroes. (1 or more floats)

-s <xSize ySize> = For each axis, information about how many samples in
outputo "x<float>": number of output samples is some scaling of the number input of
samples; multiplied by <float>o "<int>": specify exact number of samples (2 sampling
specifications) default: "x1 x1"

-a <avg #> = number of averages (if there there is only one rotation)
(unsigned int); default: "0"

-o <filename> = file to write output nrrd to (string); default: "-"
