hi guys,

does anyone know good way how to resize jpg pictures and preserve EXIF
at the same time, preferably using graphics/imagemagick? it seems that
graphicsmagick removes the EXIF information, but maybe there is some
option i missed


thanks in advance for any hints. regards,

I just resize a 60 jpg images with my bash script (see the attachment).

I open such an image and see the image info: there I can see the EXIF
information out there:
Profile-exif: 34883 bytes

and after thet follows a lot of numbers in hexadecimal format.

I don't know about EXIF information, what it is, but I suggest that you
try my script and resize your pictures (copy them in another directory
& there resize them!) and after that open such an image with display
command and see the image info (right click / menu / Image Info)!

well, it seems that imagemagick indeed preserves exif information,
whereas graphicsmagick doesn't! i thought these two should be compatible...

thanks for the input.

I don't resize many pics but for those that I do, I use imagemagick's
convert command. It does preserve the EXIF information during the
transformation. I use the following command to resize an image for a
maximum side of 800px.

$> convert -resize 800x800 image.jpg small-image.jpg

To resize multiple images you can always cook up a script. Other
applications which I use for exif manipulations are jhead and exiv2.

I use digikam to resize. I don't know about EXIF since I don't know
what that is.

EXIF is metadata stored in a JPG.
