The Python Imaging Library handles raster images; that is, rectangles of pixel data. An image can consist of one or more bands of data. The Python Imaging Library allows you to store several bands in a single image, provided they all have the same dimensions and depth. Best Pillow for Neck Pain example, a PNG image might have ‘R’, ‘G’, ‘B’, and ‘A’ bands for the red, green, blue, and alpha transparency values. Many operations act on each band separately, e.g., histograms. It is often useful to think of each pixel as having one value per band. To get the number and names of bands in an image, use the getbands() method. The mode of an image is a string which defines the type and depth of a pixel in the image. Each pixel uses the full range of the bit depth. So a 1-bit pixel has a range of 0-1, an 8-bit pixel has a range of 0-255, a 32-signed integer pixel has the range of INT32 and a 32-bit floating point pixel has the range of FLOAT32.
