Preserving EXIF info while resizing via GD
« on: April 25, 2005, 05:45:14 AM »
I like the smoothness while resizing images using GD. However, it seems that GD blows out the EXIF information. I am pretty sure about this since resizing using ImageMagick is fine but the resized pictures do not look as good.

My question is:
  + Is there a mod to make GD resizing without loosing any EXIF data? Either by not loosing it or temporary save it somewhere and then add it back to the final image?
  + Is there tweak to EXIF mod to get the data from my orginal images instead of the resized ones?
  + At last resort, how to tweak ImageMagick so that I can have the final image as I like?

Thanks,
z0

not that I'm aware of :(

yes, there is, I posted a code somewhere...probably under "Open original image ..." mod :?:

Hello people.

There are some GNU/GPL exif libraries on internet that allows writing exif data on a jpg (something that the exif lib that comes included in PHP can't do).

There are two:

http://www.ozhiker.com/electronics/pjmt/

The first one is very well documented.
Hope it helps.

Best regards.
WR.
