Hello,
I just started to use PIL 1.01b (of 11/01/99) and have a few problems:
1. I can not read black/white bitmaps (
...
File "C:\Program Files\Python\Lib\PIL\BmpImagePlugin.py", line 136, in
_open
self._bitmap()
File "C:\Program Files\Python\Lib\PIL\BmpImagePlugin.py", line 85, in
_bitmap
raise IOError, "Unknown BMP header type"
IOError: Unknown BMP header type
). I used MS Paint to save file in 1-bit per point mode.
2. I have a bitmap of 3086 x 2775 256 colors. An attempt to use viewer to
display it causes Python failure in TK80:
PYTHON caused an invalid page fault in
module TK80.DLL at 015f:00c8f329.

Is there any limits on what can be viewed?
3. An attempt to process images like:
import Image
...
fails with message:
File "C:\Program Files\Python\Lib\PIL\ImageDraw.py", line 29, in __init__
im.load()
File "C:\Program Files\Python\Lib\PIL\ImageFile.py", line 117, in load
self.map = Image.core.map(self.filename)
File "C:\Program Files\Python\Lib\PIL\Image.py", line 40, in __getattr__
raise ImportError, "The _imaging C module is not installed"
ImportError: The _imaging C module is not installed
However,
import Tkinter
import Image
...
fixes the situation. I do not understand how this is related (Python-wise).
4. In the same bitmap from 2 (3086 x 2775 256 colors), I tried to draw a
line:
draw = ImageDraw.Draw(im)
draw.line(((0, 0), im.size), fill=128)
An operation fails with message:
PYTHON caused an invalid page fault in
module _IMAGING.DLL at 015f:00d653b0.
