Summary0001297: Bad jpg output from cairo on wide bitmap
Description



The output of dot -Tjpg on the input graph appears to produce a monochrome
block. The output using -Tjpg:gd produces a correct, though much larger,
file.
Additional Information
[ellson] Bitmaps from cairo fail when x or y > 2**15

My theory is that gd, libpng, libjppeg are less restrictive and are able to handle x*y < 2*16, which allows it to handle tall or wide
images where one axis is > 2**15.

I am corresponding with the cairo list to see what the expected limits are, then I will generate a dot error if the size is exceeded.
