Spliting multipage images fast when the documents are small but very slow when the documents are large.

if seems that the following line loops through the entire document until it get the the ipageNo value and then loads the page into the _image variable.  And the for the next page it does the same loop until it reaches the iPageNo.

_image = _codecs.Load(_ImageFullPath, 0, CodecsLoadByteOrder.BgrOrGray, iPageNo, iPageNo);

is there any other way that I can do this or  Am I missing something?

 I have documents that are 12000 pages long and it takes forever.

Tiff images are basically link list so each page points to the location in the file where the next page exist and so on. This is why it takes longer on very large files to locate specific pages.
