Dear James,
I tried the following code
R, G, B = 0, 1, 2
Image1 = img.split()
Image2 = img1.split()
outR = ImageMath.eval("(a + b)", a=Image1[R], b=Image2[R])
outG = ImageMath.eval("(a + b)", a=Image1[G], b=Image2[G])
outB = ImageMath.eval("(a + b)", a=Image1[B], b=Image2[B])
Image1[R].paste(outR, None)
Image1[G].paste(outG, None)
Image1[B].paste(outB, None)
out = Image.merge(img.mode, Image1)
I am using this code for adding the values of pixels from two different
images. But again I am getting the same error, as mentioned in my previous
mail. Only time I am not getting the error is when i am converting the
images to "L", before performing eval.
Please help me out, I dont know where I am wrong.
With Warm Regards,
Bishwarup
