+# apply_images
+
+* Take calibration json as argument
+* Create blank image of width and height
+* Place idealized circles where hole punches are supposed to be
+* Place fiducials in corners of images
+* Take up to 4 images as arguments
+* Perform AffineTransform on as many source locations as needed
+* Place images according to AffineTransform
+* Write final image out
+
+### Potentials needs
+
+* One time xy offset, calibrated to hole punches
+* Hole punch several sheets at the same time, calibrate to one and print on them
+* OR
+* Calibrate, then print on un-punched sheets and place guides for punching
+* (this may be less reliable)
+
+# apply_svg
+
+* Create svg document scaling width and height to 96dpi equivalent
+* Normalize all measurements to 96dpi equivalent
+* Place idealized circles where hole punches are supposed to be
+* Take up to 4 svg files as arguments
+* Find best fit for svg within 4 frames, rotation, scale and position
+* Place or embed or re-write svg within frame, one at a time
+* Write out final svg
+
+
+### Potential needs
+
+* One time xy offset, calibrated to hole punches
+* Special board to draw this on (as opposed to free form mat)
