Exploring Python's PIL Library

What RGB code represents the color red?

• (0, 255, 0)

• (255, 255, 0)

• (0, 0, 255)

• (255, 0, 0)

How do you create a new image using the PIL library?

• Use Image.new('RGB', (width, height), color) to create a new image.

• Invoke Image.new_image('RGB', (width, height), color) for image creation.

• Call Image.make_new('RGB', (width, height), color) to create an image.

• Use Image.create('RGB', (width, height), color) to generate a new image.

What command would you use to save an image in PIL?

• image.save('filename.png')

• image.save_as('filename.png')

• image.write('filename.png')

• image.store('filename.png')

Which function is used to display an image in a window?

• imshow

• displayImage

• showPicture

• renderPhoto

How can you draw a rectangle using the PIL library?

• from PIL import Image, ImageDraw # Create a blank image image = Image.new('RGB', (200, 100), 'white') draw = ImageDraw.Draw(image) # Draw a rectangle (x0, y0, x1, y1) draw.rectangle([50, 25, 150, 75], outline='black', fill='blue') # Save or show the image image.show()

• draw.rectangle((50, 25), (150, 75), color='red')

• from PIL import Rectangle, ImageDraw

• image = Image.create('RGB', (200, 100), 'black')

What method would you use to get the size of an image?

• Check the 'dimensions' attribute of the image object.

• Use the 'length' method to determine the image size.

• Use the 'size' property or equivalent method in the programming language.

• Apply the 'getSize()' function to retrieve image dimensions.

How do you apply a line graphic primitive in PIL?

• Use `ImageDraw.Draw(image).line((start, end), fill=color, width=width)`.

• Use `ImageDraw.line(image, (start, end), color)` to draw a line.

• Use `ImageDraw.Draw().line((start, end), color)` without specifying the image.

• Call `draw.line((start, end), fill=color)` directly without an image context.

What RGB code corresponds to the color blue?

• (0, 0, 255)

• (255, 0, 0)

• (255, 255, 0)

• (0, 255, 0)

How can you create an ellipse in a PIL image?

• Use `ImageDraw.polygon(points, fill=color)` to create a polygon shape.

• Use `ImageDraw.line(points, fill=color)` to draw a line.

• Use `ImageDraw.rectangle(bbox, fill=color)` to draw a rectangle instead.

• Use `ImageDraw.ellipse(bbox, fill=color)` where `bbox` is a tuple defining the bounding box of the ellipse.

What is the purpose of the 'load' command in the PIL library?

• To load an image into memory for processing.

• To save an image to disk.

• To convert an image to a different format.

• To display an image on the screen.
