A full-color image (the Tk photo image type), stored internally with a varying degree of transparency per pixel. It can read and write GIF, PPM/PGM and (in Tk 8.6 and later) PNG files, read SVG files (in Tk 9.0 and later), and be drawn in widgets. Inherits from Image.
Blank the image; that is, set the entire image to have no data, so that it is displayed as transparent and the background of whatever window it is displayed in shows through.
Return the color of the pixel at coordinates (x, y) as an (r, g, b) tuple of three integers between 0 and 255, representing the red, green and blue components respectively.
Set pixels of the image to the colors given in data, which must be a string or a nested sequence of horizontal rows of pixel colors (for example "{red green} {blue yellow}").
