python - 大きな画像をつなぎ合わせる - Python.exe が機能しなくなった

Question

Python スクリプトを使用して、大きな画像 (10000 x 10000 ピクセル) を連続してつなぎ合わせています。8 枚の画像のうち最初の 6 枚を一度に 1 つずつつなぎ合わせることができます。ただし、この時点を超えてさらに画像をステッチすると、「Python.exe が動作を停止しました」というメッセージが表示されます。

以下のコード:

from PIL import Image
import getopt, sys

args = sys.argv
ImageFileList = []
MasterWidth = 0
MasterHeight = 0
filename = ""
row = True

print """
Usage: python imageconnector.py  [OPTIONS] [FILENAME] [FILE1] [FILE2] ...[FILE...]...
Combines [FILE1,2,...] into one file called [FILENAME]

OPTIONS:

-o <r/c>        Stitch images into a row or a column. Default is row.
-c <colour>     Change background fill colour. Default is black.
