The following code opens an image named "hopper" and creates a Draw object using it to then draw two lines. First, a line from the top left (0,0) to the bottom right. Then, a line from the top right to the bottom left.
```python
import sys
from PIL import Image, ImageDraw

with Image.open("hopper.jpg") as im:

    draw = ImageDraw.Draw(im)
    draw.line((0, 0) + im.size, fill=128)
    draw.line((0, im.size[1], im.size[0], 0), fill=128)

    # write to stdout
    im.save(sys.stdout, "PNG")
```

Draw a Gray Cross Over an Image (Pillow)

The Draw class has multiple functions to draw lines or shapes over an image object. These functions take coordinates as arguments to specify the where the figures will be drawn.
Possible figures are:
- Arc
- Chord
- Ellipse
- Line
- Pie Slice
- Point
- Regular Polygon
- Rectangle
- Rounded Rectangle

The ImageDraw class allows for generating simple 2D graphics. It can be used for creating new images, or annotating/retouching existing images.
The central function of an ImageDraw object is the ImageDraw.Draw() function. This creates an object that can be used for drawing inside an image given through an argument.
```python
d = ImageDraw.Draw(image)
```

Drawing Lines and Shapes (Pillow)

The ImageFont class allows for ImageDraw objects to incorporate font text. ImageFont supports both bitmap fonts and OpenType/TrueType fonts. The former uses Pillow's own formats, .pil and .pbm, and the latter uses the .otf and .ttf font file formats.
Use ImageFont.load() to load a bitmap font and ImageFont.truetype() for a OpenType/TrueType font.
ImageDraw's font() function can then be used to draw the text into an ImageDraw object.
```python
font = ImageFont.truetype(fontfile)
d = ImageDraw.Draw(image)
d.text(position, string, color, font)
```
```python
font = ImageFont.truetype(fontfile, size)
d = ImageDraw.Draw(image)
d.text(position, string, color, font)
```
