Python Imaging Library Reference Notes

• The official reference is here.
• ImageTK module
  • BitmapImage(image, foreground="color")
    Convert an image into a bitmap
  • PhotoImage(image)
    Turns any image format (jpg, png, etc.) into a Tkinter compatible image
• Image module
  • img.open(filename)
  • img.save(outfile, format) If format omitted, bases file type on extension of filename
  • img.resize(size) size in (height, width) as a tuple
  • img.rotate(angle) rotates image counter-clockwise around the center
  • img.thumbnail(size) creates a thumbnail of the image
• ImageEnhance module
  • NOTE: All classes in this module use the method "enhance(factor)". So code would look like:
    pic = ImageEnhance.Color(image)
    pic.enhance(1.5)
  • Color(image) 0.0 = black and white, 1.0 = original
  • Brightness(image) 0.0 = black, 1.0 = original
  • Contrast(image)0.0 = solid grey, 1.0 = original
  • Sharpness(image) 0.0 = blurred, 1.0 = original, 2.0 = sharpen
• ImageFilter module
  • NOTE: These are predefined routines to use with the filter method of the Image class. A sample code would look like: img.filter(ImageFilter.BLUR).
