extract exif thumbnail

[baibaichen]

Does IM support extracting exif thumbnail from tiff and jpeg?

I search the forum and documentation but can't find solution.

Thanks

Assume your EXIF profile is embedded in an JPEG image. Use this command:

• convert image.jpg thumbnail:thumb.jpg

• convert image.jpg thumbnail:thumb.jpg

it doesn't work

I took a look at code, it looks like that covert doesn't process the last parameter, it always treat it as output filename.

can you post a link to an example image so that the IM folks can test with it.

The JPEG file that i used is very popular, and comes from Nikon D70s, I can extract the exif thumbnail from jhead with the same file.

where is the documentation about thumbnail:

thanks

"thumbnail:" is documented on http://www.imagemagick.org/Usage/formats/

We don't all have a Nikon D70s, so posting your file will help diagnostics. When I use the command on an image from my camera:

Code: Select all

convert PICT0001.JPG thumbnail:th0001.jpg

I get the expected image, which is the (rather horrible) thumbnail created by my camera.

what version of IM are you using? perhaps you need an upgrade to make thumbnail: work properly?
