[Pythoncard-users] PIL to wxImage translation

[Kevin A. <al...@se...>]

Cliff Wells [log...@ea...] passed on some code that he
uses to convert between PIL and wxImage formats. Given the large number of
image manipulation routines in PIL, any wrapper classes we do for PythonCard
will probably use PIL or at least provide easy translation to and from PIL.

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


Here are some resources I mentioned previously, but are worth mentioning
again.
