Resolution limit exporting to TIFF or JPG

Aug 29, 2012 2:54 AM

Hi,

 

I can't export 4500x2500mm image with 300 or even 150 dpi. Need to do it with only 96 dpi.

 

I'm using Acrobat X Pro.

 

What is the limit and why is there limit?

    That combination is way too large for anything to handle, especially a 32-bit application such as Acrobat. 4500mm at 300dpi is 53150 pixels wide (giving a 1496 megapixel image).

    Sounds like a job for a pro photo tool like Photoshop, but it may be too large for that. I think PSD is limited to 30,000 x 30,000 pixels.

    Photoshop CS and later can work with documents up to 300,000 pixels in each dimension, but it's limited by RAM and when saving a document you have filesize limits due to the bit depth of the headers:

     

    PSD = 2GB

    PSB = 4GB

    Tiff = 4GB

     

    A Tiff file can in theory contain an image with a 4 billion pixel canvas dimension, but in practice it would exceed the filesize.
