-quiet mode not working

[fmw42]

My correspondence with Anthony Thyssen on this topic (where bogus.png does not exist). I was working with IM v6.3.5.7


| If I do the following:
|
| if convert -regard-warnings "bogus.png" "tmp.png"
| then
| : ' do something else'
| else
| echo "--- cannot read input file ---"
| exit 1
| fi
|
|
| Then I get:
|
| convert: unable to open image `bogus.png': No such file or directory.
| convert: unable to open file `bogus.png'.
| convert: missing an image filename `tmp.png'.
| --- cannot read input file ---
|
|
| If I add -quiet as follows:
|
| if convert -regard-warnings -quiet "bogus.png" "tmp.png"
| then
| : ' do something else'
| else
| echo "--- cannot read input file ---"
| exit 1
| fi
|
|
| then I still get the same result:
|
| convert: unable to open image `bogus.png': No such file or directory.
| convert: unable to open file `bogus.png'.
| convert: missing an image filename `tmp.png'.
| --- cannot read input file ---
|

That is a definate BUG. (Anthony)

The -quiet option suppresses warnings. The output you are receiving is an error.

Okay then the alternative is to capture the error output and print it at the appropriate time. Eg

Code: Select all

error=`convert -quiet -regard-warnings ...... 2>&1`
