NConvert bug -multi option

Post by cday » Sat Apr 13, 2019 7:17 pm

A regression seems to have been introduced for the -multi option somewhere between NConvert 6.51 and 7.25.

The following code works as expected with the attached test PNGs:

Code: Select all

nconvert_6.51 -out pdf -multi -c 5 -q 80 -o M.pdf *.png

But the following code produces a malformed multipage file using the same PNGs:

Code: Select all

nconvert_7.25 -out pdf -multi -c 5 -q 80 -o M.pdf *.png

Malformed multipage files also seem to be produced for some other file extensions, possibly dependent on the compression method used which complicates investigation, hopefully due to the same regression.
