Supporting 9-billion pixel PSB
Posted: 2012-10-27T19:58:03-07:00
Hello,
I have a very large image in the Adobe PSB format and ImageMagick is telling me the following when trying to downscale and convert it:
I do not own a copy of Photoshop, but have downloaded a trial to verify the image is viewable and correct. The image is 24.6 GB and the dimensions are 108,200 by 81,500 pixels. Here is the website: http://www.eso.org/public/images/eso1242a/. A torrent file is available to download it via reddit: http://redd.it/121r3s.
I downloaded the latest version of ImageMagick as of this post, compiled from source
I found this forum saying ImageMagick might be trying to allocate an insane amount of temporary storage: viewtopic.php?f=1&t=11494. This is the output I have:
I hope I am not doing something stupid! Is there any advice anyone may have (purchasing Adobe Photoshop is not an option)?
Thank you!
