We start with the available filters: # convert -list filter Bartlett Blackman Bohman Box Catrom Cubic Gaussian Hamming Hanning Hermite Jinc Kaiser Lagrange Lanczos LanczosSharp Lanczos2 Lanczos2Sharp Mitchell Parzen Point Quadratic Robidoux Sinc SincFast Triangle Welsh
I haven't the first clue how to compare all of these so here is what I am trying to accomplish in a script for repeated usage:
I have an image that is mostly text. I am trying to reduce the size of the image to a fixed width (usually about 20%) while keeping the text as readable as possible.
If I do this in GIMP, "cubic" will not produce the desired result. Lanczos comes close. I assume that I can get even closer with "convert." Slow is fine. Can some kind sole, more clever with graphics than I am, suggest the -filter * that I am looking for?
TIA
