That's my hole Question,

when i working with ImageMagick, does it obtain the metadata of an image in any way?

Kind regards

Yes. Try running for starters.

Does it obtain them too, when i convert an image to another format or size or whatever i want?

What happened when you tried?

I can't test it right now. That's why i am asking.

Yes, if the convert command is not too complex with other images involved and the new format supports that meta data.

But you have not said what type of meta data, nor what formats? Also please always provide your version of IM and platform when asking questions.

Thanks for your answers!

Kind regards

The question is too vague. ImageMagic reads most metadata of images. It has to, to find width and height etc. It may not read all metadata, because some isn't relevant to ImageMagic.

Okey, so EXIF Metadata wont be read? and whats up with XMP or ICC Profile?

And whats going on with the Metadata when i do a Calculation with -flatten?

Thanks in advance

EXIF data is read. See http://www.imagemagick.org/script/escape.php . Manufacturer-specific data (such as "Nikon:") is not. (EDIT: Or, rather, "Nikon:" metadata is read but not accessible through "-format".)

ICC profiles are read, and used for colour conversions.

And which Metadata is stored when i use -flatten? -flatten is for multiple layers, when i have to images i use as 2 layers which metadata is stored in the new created image, or is there no metadata from the original images?

Output metadata will come from the first image in the list.
