1994.12.15 00:38 "Minor problem with tif_read.c with stripped planar images.", by Gordon Clare

I've just fixed a problem when using stripped planar images.
TIFFReadEncodedStrip does not figure out truncated strip
sizes correctly for the last strip in the image.

I'm currently using:
VERSION		3.3beta
tiff.alpha	define ALPHA 015

*** OLD/tif_read.c       Tue Oct 11 17:37:27 1994
--- NEW/tif_read.c       Thu Dec 15 09:33:48 1994

*** 140,146 ****
         * Calculate the strip size according to the number of
         * rows in the strip (check for truncated last strip).
         */
!       if (strip != td->td_nstrips-1 ||
            (nrows = td->td_imagelength % td->td_rowsperstrip) == 0)
                nrows = td->td_rowsperstrip;
        stripsize = TIFFVStripSize(tif, nrows);

                nrows = td->td_rowsperstrip;
        stripsize = TIFFVStripSize(tif, nrows);
