Large size images

[paulohess]

Hi

I have an image around 2G and am trying to use "convert" to create a JPG thumb.
I get this error :
convert: unable to open image a.TIF - Value too large for defined data type.

For the sake of the image quality, I can't re-size the original image ...

is there any parameter or way to make IM read the image in ...

Thanks
P.H.

What platform/OS and what version of IM are you using. What is the actual width x height of the image? Is that beyond the tiff specs? If you are running out of memory, then see http://www.imagemagick.org/Usage/files/#massive

Can you do

identify -verbose image.tif

on your image without error?

I can't run:
$ identify -verbose F8V0.TIF
identify: unable to open image `F8V0.TIF': Value too large for defined data type.

W =7707
H= 9431

Horizontal & Vertical Resolutions: 400 dpi

Are you able to post a link to your file so others can test it? And what is your exact command line?

actually it works ... I, by mistake, was running an older version.

Thank you.
