convert.exe creates two images, not one

I am converting some .tiff images to jpegs, and resizing them at the same time (creating thumbnails)
When i do this, it generates two images, instead of one as I expected. Is this a bug or a feature?
Convert.exe original.tiff new.jpg
results in
new-0.jpg
new-1.jpg
instead of
new.jpg
Thanks!

There are probably two images in your TIFF file. If you only want to process the first page, you can type 'original.tiff[0]' instead of just 'original.tiff', for example.

That is great information, and it does work, thank you!
Do you know, i did not see anywhere, a way to select this without using the special [..], and instead a command line switch?
Thanks either way!

identify image
will list the image info for each frame/page
or use
convert image -format "%n" info:
to tell you the number of frames/pages. see
http://www.imagemagick.org/script/escape.php
The only way to select one or more is by using the [...] bracket notation. See
http://www.imagemagick.org/script/comma ... essing.php under selecting frames

Code: Select all
convert tiff_image delete 1--1 image.jpg
The delete deletes all images from 1 (second image index 1) to -1 (last image). if there are no images in that command does nothing.
