-silent

There is a "-silent" option, according to the documentation http://www.imagemagick.org/script/comma ... php#silent

But it causes a fail, in v6.9.2-5 and v7:

Code: Select all

convert rose: -silent r.png

convert.exe: unrecognized option `-silent' @ error/convert.c/ConvertImageCommand
/2950.

It's not listed as a "convert" option, though: http://www.imagemagick.org/script/convert.php

Looking at the source code,
In magick/option.c: { "-silent", 1L, NonConvertOptionFlag, MagickFalse },
In magick/option.h: NonConvertOptionFlag = 0x4000, /* Option not used by Convert */

Only the "import" tool seems to accept the "-silent" option.

Ah, so it isn't, thanks. Perhaps that point could be made in the documentation http://www.imagemagick.org/script/comma ... php#silent , which does say:

Unless otherwise noted, each option is recognized by the commands: convert and mogrify.

I've edited the source file accordingly for the commandline options page.
