Since I've been asked for them so often (three times and counting!), I'll
post them to the list. I believe I got the original code from Piddle... it's
been a while, so I'm not too sure. And yes, those are tab-indentations (damn
you four-spacers!).
def PILToWX(image):
"convert a PIL image to a wxImage"
if (image.mode != 'RGB'):
image = image.convert('RGB')
imageData = image.tostring('raw', 'RGB')
imageWx = wxEmptyImage(image.size[0], image.size[1])
imageWx.SetData(imageData)
return imageWx
def WXToPIL(image, mode = 'RGBA'):
"convert a wxImage to a PIL RGBA image"
imageData = image.GetData()
size = (image.GetWidth(), image.GetHeight())
imagePIL = Image.fromstring('RGB', size, imageData)
if mode != 'RGB':
imagePIL = imagePIL.convert(mode)
return imagePIL
