# teem-ilk(1)

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

## 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 image o "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 resampling o "translate:x,y": shift image by vector (x,y), as measured in pixels o "rotate:ang": rotate CCW by ang degrees o "scale:xs,ys": scale by xs in X, and ys in Y o "shear:fix,amnt": shear by amnt, keeping fixed the pixels along a direction \<fix\> degrees from the X axis o "flip:ang": flip along axis an angle \<ang\> degrees from the X axis o "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 outward o "wrap": do wrap-around on image locations o "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

  output: o "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: "-"
