annotate libinterp/dldfcn/__tiff__.cc @ 31137:233130c0b1f6
Tiff writeEncodedStrip: changed strip dimension check behavior to mimic matlab
* __tiff__.cc(write_strip): changed the way ring strip dimensions are handled
by using resize instead of aborting to mimic matlab behavior.
* Tiff.m: rewrote the tests to match the neww behavior.
