Because the imageData holds the data for the pixels being displayed (even if they are all transparent/no color), so it cannot be empty unless the image has zero width and/or zero size. If the image object has a size, it has pixels, therefore it has imageData (even all zeros) for each pixel. However, if you create a new image and look at the text property of the image, you will see that it's empty until you paint something in the image. -- Jeanne A. E.
