- Summary
- -------
-
- I need advice (or preferably code) to convert 2D data sets (512 x 298 of
- 8 bit integer data) to contour lines.
-
- Blurb
- -----
-
- I have a number of microscopy images which I want to contour and my
- attempts to find explanations/code to do this have failed so far, so...
-
- ...Could some kind soul point me in the direction of an uncomplicated
- explanation of (or better still, explanation and code for) contouring
- arbitrary sized rectangular arrays of bytes?
-
- I have one code example (from Doctor Dobbs Journal I think) which
- contours a 20 x 20 array of floats and outputs postscript. The
- printer I tried it with didn't like it and (much as I wish I could say
- I did) I couldn't work out much of what was happening in the code.
-
-
- Many thanks in advance,
-
