Hi Mike
How do I create a PIL Image instance from a wxImage instance.
In your code you have done the reverse, ie creating a wxImage instance
from a PIL image.
img = Image.open(file,'r')
self.wxImg.SetData( img.convert( "RGB").tostring() )
How do I use the GetData() on wxImage() to create a PIL image.
I tried,
img = Image.open(str(self.wxImg.GetData()))
But python runtime complains that the data is NULL padded which is correct.
since the chunk is binary.
Do I need to call 'encode()' on the chunk to use the above ?
If so what encoding?
Thanks
Anand
