💖 TEEM-ILK — (I)mage (L)inear Trans(X-->K)forms 💖

okay bestie, sit down, hydrate, and let me tell you about teem-ilk, a lil user command from the Teem fam. It's giving "math but make it fashion" and honestly? It ate. 🦋

✨ SYNOPSIS ✨

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

and then the rest of the glow-up continues like this:

-t <xform0 ...> [-k <kernel>] [-min <xMin yMin>] [-max <xMax yMax>]
[-b <boundary>] [-bg <bg0 bg1 ...>] [-s <xSize ySize>] [-a <avg #>]
[-o <filename>]

🌸 DESCRIPTION 🌸

So /usr/bin/teem-ilk is literally (I)mage (L)inear Trans(X-->K)forms. What it does: it applies linear (homogenous coordinate) transforms to a given image, and it uses whatever kernel you hand it for the resampling. That's the whole vibe. ✨

And here are all the little knobs and dials, no skips, no cap:

• @file ... — response file(s) containing command-line arguments. like, a file full of flags. iconic. 📄
• -i <image> — the input image. default: "-"
• -0 <origin> — where to location (0,0) prior to applying transforms.
  • "u:<float>,<float>" — locate origin in a unit box [0,1]x[0,1] which covers the original image
  • "p:<float>,<float>" — locate origin at a particular pixel location, in the index space of the image
  • default: "p:0,0"
• -t <xform0 ...> — the transform(s) to apply to image. Transforms are applied in the order in which they appear. 👑
  • "identity" — no geometric transform, just resampling
  • "translate:x,y" — shift image by vector (x,y), as measured in pixels
  • "rotate:ang" — rotate CCW by ang degrees
  • "scale:xs,ys" — scale by xs in X, and ys in Y
  • "shear:fix,amnt" — shear by amnt, keeping fixed the pixels along a direction <fix> degrees from the X axis
  • "flip:ang" — flip along axis an angle <ang> degrees from the X axis
  • "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.
  • "bleed" — copy values at image border outward
  • "wrap" — do wrap-around on image locations
  • "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. (2 sampling specifications) default: "x1 x1"
  • "x<float>" — number of output samples is some scaling of the number input of samples; multiplied by <float>
  • "<int>" — specify exact number of samples
• -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: "-"

not me listing every single one because we do NOT gatekeep around here 💅 every flag got its moment, periodt.

and that's the whole page!! 🫶 this was Teem version 1.11.0, dated April 2012 — yes she's an elder but she still slays, no cap. bye babes 💖🎀🦋
