esimov / triangle

Version: 1.0.3
When a 1px height (e.g. 1x1, 10x1, 100x1) image is given as an input, triangle fails to run.
(FYI a 1px width (e.g. 1x10, 1x100) image is successfully processed)

% triangle -in test.jpg -out out.jpg
Generating triangulated image... -panic: runtime error: index out of range

Failing to process such an image is fine, but is it possible to give a more informative message (like "the input is too small")?

@equal-l2 thank you for reporting this issue. This is fixed now. Please revise it and tell me if is still reproducing.

It successfully emits message now, though there's some typo in the message.

Line 97 in 5d134ce

err := errors.New("The image widht and height must be greather than 1px.\n")

I think widht should be width and greather should be greater.

Thanks for notifying this, i have corrected them.

Anyway, the problem has solved. Thank you for fixing.
