Question

I had a scanned multipage TIFF image and needed to split each page out into individual files.

This is easy to do in by leveraging the .NET framework and C#, but since I did not have all the development tools installed on the machine I was using, I instead opted to use IronPython (via ipy.exe) to quickly script the processing logic.

Using Stack Overflow as a ‘blog’ engine, I’ll provide an answer to my own question. Comments, suggestions, alternatives, etc. are welcome!

Here is one way to do this – tweak as needed.

import clr
clr.AddReference("System.Drawing")

from System.Drawing import Image
from System.Drawing.Imaging import FrameDimension
from System.IO import Path

# sourceFilePath - The full path to the tif image on disk (e.g path = r"C:\files\multipage.tif")
# outputDir - The directory to store the individual files.  Each output file is suffixed with its page number.
def splitImage(sourceFilePath, outputDir):
     img = Image.FromFile(sourceFilePath)

     for i in range(0, img.GetFrameCount(FrameDimension.Page)):

         name = Path.GetFileNameWithoutExtension(sourceFilePath)
         ext = Path.GetExtension(sourceFilePath)
         outputFilePath = Path.Combine(outputDir, name + "_" + str(i+1) + ext)

         frameDimensionId = img.FrameDimensionsList[0]
         frameDimension = FrameDimension(frameDimensionId)

         img.SelectActiveFrame(frameDimension, i)
         img.Save(outputFilePath, ImageFormat.Tiff)
