Question

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.
