Its it possible to transform image format - i was hoping the grey scale node would output an true greyscale image not B&W RGBA ?

Hi Im using image.sample.color to calculate image brightness. I was wondering about converting the image to grey scale and hacking the sample node code to work with that, reducing the number of calculations by 4. As it happens this isn't such a priority as the plugin i have created is running reasonably efficiently. Thanks for you response.
