I've an error opening a gray sunrasterfile, with this code:
from PIL import Image
graysun = Image.open("grey.ras")
d = graysun.load()
I get:
File "C:\Python27\lib\site-packages\PIL\ImageFile.py", line 148, in load
self.mode, self.size, a[1], a[2]
IndexError: tuple index out of range
I found a way to patch "SunImagePlugin.py" to correct this issue, line 77 I have replaced:
self.tile = [("raw", (0,0)+self.size, offset, (rawmode, stride))]
by:
self.tile = [("raw", (0,0)+self.size, offset, (rawmode, stride, 1))]
The third item of tupple correspond to orientation.
According to http://www.pythonware.com/library/pil/handbook/decoder.htm
<< When used in a tile descriptor, the parameter field should look like: (raw mode, stride, orientation)
(...) orientation: Whether the first line in the image is the top line on the screen (1), or the bottom line (-1). If omitted, the orientation defaults to 1. >>
Seems like the orientation parameter can't be omitted.
I'm not sure if problem should be fixed in SunImagePlugin.py to add orientation as I've done, or in ImageFile.py to accept missing orientation.
