[Originally posted by akich on 2008-06-22 13:21:36-07]I tried to extract the thumbnail image, but something is going wrong. but I don't know what. the command I used:
perl C:\Programme\exiftool\exiftool -b -ThumbnailImage "G:\exiftool tests\1_crop.jpg" > "G:\exiftool tests\thumb.jpg"
for an other operation, I used the following command and this works fine:
perl C:\Programme\exiftool\exiftool -all= -tagsfromfile "G:\exiftool tests\1.jpg" -exif:all "G:\exiftool tests\1_crop.jpg"

The commands look ok. But if you
removed the metadata with the second
command then there will be no thumbnail
to extact.

if it looks ok, than I don't understand why it doesn't works. the thumb is inside the file, I checked it with exifer.

What is the output of this command?:
perl C:\Programme\exiftool\exiftool -ThumbnailImage "G:\exiftool tests\1_crop.jpg"
You should get something like this:
Thumbnail Image : (Binary data #### bytes, use -b option to extract)
If you do, then the -b option should work, and redirecting the
output to a file should also work. If you don't, then exiftool can't find the
thumbnail. In this case I would like to see a sample, because this would
be new to me. At any rate, if you can't figure it out, a sample image may
be useful so I can see exactly what you are dealing with.

hi phil
I tried it with the windows cmd-window. Without the -b option nothing happened. I also got no message. With the -b option it works fine. So there must be an other problem in my application, which I had to find.
