[Image-SIG] WG: How to create instance of Image ?

[Graf Patrick]

maybe a simple problem, if you know the solution....

Hi all,


I'm trying to write a class for my own image processing needs.
In this matter, I'm having problems with some variable declarations
I'd like to create a image variable, let's call it myPicture .

So I tried to declare

myPicture = Image.Image()

outside the class. This works fine for opening an image like

myPicture.open("MyImage.jpg")

file but I get an error when I try to save the image.

Traceback (innermost last): File 
"D:\Inetpub\wwwroot\test_image\smPicUpload2.py", line 203, in ? 
smPic.save(savePath) File "D:\Inetpub\wwwroot\test_image\smPicture.py", 
line 45, in save myPicture.save(filename) File 
"c:\python.151\PIL\Image.py", line 615, in save 
SAVE[string.upper(format)](self, fp, filename) File 
"c:\python.151\PIL\JpegImagePlugin.py", line 297, in _save raise IOError, 
"cannot write mode %s as JPEG" % im.mode IOError: cannot write mode as JPEG 



Thanks for any help !

Note: Is it possible to use an Image object and pass it to a procedure ?
