Legacy ImageMagick Discussions Archive

snibgo, that's awesome, thank you! Just what I wanted.

I'm using IM for simple convert operations, like this: convert image.jpg image.png
Could you please tell, if there is any way to obtain a unique or random filename for resulting file using IM only abilities without using system variables (I have some specific environment restrictions).

As I know ...

I'm not a programmer but I would offer the following logic to solve this:

0. Processing file without suffix
1. Tying to identify using all available formats, except ICO
2. If file is not recognized, then trying to put ico: at the begining of the filename (as suggested by magick )
3. If successful ...

It works, thank you.
However, my objectives include automatic usage of "convert" command on files with random formats and some of them do not have suffixes. ImageMagic works perfectly for my purpose, except for the case with ICO files. It would be great if you add the same identification support for ...

My English is not perfect, so just to clarify, here are steps to reproduce the error:

1) Take the googleg_lodp.ico file
2) Rename it to googleg_lodp (without .ico suffix)
3) Execute the command: magick identify googleg_lodp

Same file with added suffix:
magick identify google.ico
google.ico[0] ICO 16x16 16x16+0+0 32-bit sRGB 5.43KB 0.000u 0:00.000
google.ico[1] ICO 32x32 32x32+0+0 32-bit sRGB 5.43KB 0.000u 0:00.006

I used this file:
https://www.google.com/images/branding/product/ico/googleg_lodp.ico

UPD: Sorry I ...

IM is not identifying ICO files without *.ico suffix. Therefore, all commands are returning the same error:

identify: no decode delegate for this image format `' @ error/constitute.c/ReadImage/508.
convert: no decode delegate for this image format `' @ error/constitute.c/ReadImage/508.
