convert in.dng out.png resets timestamp of in.dng

[glennrp]

Relaying a bug report found on StackOverflow:

Code: Select all

magick in.dng out.png

updates the timestamp of "in.dng".

But

Code: Select all

ufraw-batch --silent --create-id=also --out-type=png --out-depth=16 --output=out.png in.dng

which I believe is the "delegate" command used by ImageMagick, does not.

Even worse, if I first make the in.dng unwriteable

Code: Select all

 chmod 400 in.dng
 magick in.dng out.png 

then convert (a.k.a magick) successfully creates out.png but removes in.dng, without any error or warning message.

This test with ImageMagick-7.0.0-0 Q16 x86_64 2016-02-12 and ufraw-batch version 0.22.
