Regression: may not write any output file, but advertizes success

[axeld]

Hi there!
With recent versions (tested with 7.0.8-17 and 7.0.8-24), ImageMagick stumbles over this file when invoked like this:

Code: Select all

magick.exe convert floor.jpg -resize 600x500> -profile sRGB_v4_ICC_preference.icc output.png

There is no error message, and the application exits successfully. However, "output.png" does not exist.
An earlier version I still had here (6.9.3) has no issues creating the output file; it only shows the following message during conversion:

Code: Select all

convert.exe: color profile operates on another colorspace `icc' @ error/profile.c/ProfileImage/1022.

That output hints to some issues of the file itself; at least I couldn't make any sense of this color space warning.
The profile is a standard profile from http://www.color.org, identifying the file shows the following output:

Code: Select all

floor.jpg JPEG 400x250 400x250+0+0 8-bit sRGB 72804B 0.016u 0:00.002

Looks like there is an inccorect color profile attached to the image already that causes the warning. Might hint into the direction this bug is coming from.

For IM v7, I suggest you use "magick", not "magick convert".

The input image is RGB, but has an embedded CMYK profile.

What is your platform? Windows will interpret your command up to the ">", then will redirect the output to a file. You need quotes around "600x500>" or an escape ^> or both.

"magick" and "magick convert" should be the same, right? I executed the line as is in PowerShell which seems to do the 'right' thing; it originated from a script without shell parsing, though.

No, they are not the same. Magick convert reverts to IM 6 behavior similar to calling convert in IM 6. If you want IM 7 behavior then use just magick.

That's interesting! I could not find any documentation about the actual differences -- where can I get more information on that?

Thanks for the link! I didn't watch out for "porting" when looking for it.

I've noticed there is a proper issue tracker at github, so I created a ticket over there: https://github.com/ImageMagick/ImageMagick/issues/1492
Please comment there if you have more input on this bug.
