ImageTk Module
The ImageTk
module contains support to create and modify Tkinter BitmapImage and PhotoImage objects from PIL images.
For examples, see the demo programs in the Scripts directory.
- class
PIL.ImageTk.
BitmapImage
(image=None, **kw) A Tkinter-compatible bitmap image. This can be used everywhere Tkinter expects an image object.
The given image must have mode “1”. Pixels having value 0 are treated as transparent. Options, if any, are passed on to Tkinter. The most commonly used option is foreground, which is used to specify the color for the non-transparent parts. See the Tkinter documentation for information on how to specify colours.
参数: image – A PIL image. height
()Get the height of the image.
返回: The height, in pixels.
width
()Get the width of the image.
返回: The width, in pixels.
- class
PIL.ImageTk.
PhotoImage
(image=None, size=None, **kw) A Tkinter-compatible photo image. This can be used everywhere Tkinter expects an image object. If the image is an RGBA image, pixels having alpha 0 are treated as transparent.
The constructor takes either a PIL image, or a mode and a size. Alternatively, you can use the file or data options to initialize the photo image object.
参数: - image – Either a PIL image, or a mode string. If a mode string is used, a size must also be given.
- size – If the first argument is a mode string, this defines the size of the image.
- file – A filename to load the image from (using
Image.open(file)
). - data – An 8-bit string containing image data (as loaded from an image file).
height
()Get the height of the image.
返回: The height, in pixels.
paste
(im, box=None)Paste a PIL image into the photo image. Note that this can be very slow if the photo image is displayed.
参数: - im – A PIL image. The size must match the target region. If the mode does not match, the image is converted to the mode of the bitmap image.
- box – A 4-tuple defining the left, upper, right, and lower pixel coordinate. If None is given instead of a tuple, all of the image is assumed.
width
()Get the width of the image.
返回: The width, in pixels.
