Convert multipage tiff into blocks of 100 pages

[mundi]

Hello,

I have a big tiff file of over 1000 pages and want to to split it up in single paged tiffs I use the command

Code: Select all

convert blah.tif -compress JPEG blah_page%04d.tif

The problem is that this uses all memory and aborts. What I want to do now is splitting the tif in smaller tifs of
100 pages then split them up in 1 paged tiffs.

My question: is there a command to splitt my tiff in 100 paged tiffs?

try

Code: Select all

convert blah.tif[0-99] -compress JPEG blah_page%04d.tif

But IM may still need to read the whole tiff file before processing only the first 100. So you may still need to have a large amount of RAM.
