Dear All,

Sorry to bother this list for a simple question:
are there any MagickCore functions to detect what graphic format
(.gif, .jpg, etc.) for a given file?

Thanks.

I think I found the answer myself: just just image->magic.

If you just want to detect the format, use PingImage() instead of ReadImage(). PingImage() is lightweight.

The 'magick' part is also available (completely outside of IM) using the "file" command. IM itself does similar things in determining image format styles.
