In Scratch, what is a bitmap image?

Why do we use bitmap images in Scratch?

• They make images look like cartoons

• They are used only for text

• They are better for drawing shapes and lines

• They let us make very detailed pictures with lots of colors

Bitmap images in Scratch can be resized without losing quality.

• True

• False

What can't you do with bitmap images that you can do with vector images?

• Change the color of the whole image at once

• Edit each tiny part of the image, like each pixel

• Draw shapes with lines

• Make the image very big without it getting blurry

Bitmap images are made of tiny squares called pixels.

• True

• False

Match the following

• draw directly on a bitmap image

• 
• fill an entire area with one color

• 
• draw lines and shapes on a bitmap image

• 

The "Eraser" tool in Scratch can remove parts of a bitmap image.

• True

• False

What is the difference between using the "Select" tool in vector mode and bitmap mode in Scratch?

• In vector mode, "Select" picks whole objects, while in bitmap mode, it crop parts of the image

• In vector mode, "Select" picks parts of the image objects, while in bitmap mode, it picks whole objects

• "Select" works the same way in both modes

• "Select" is not used in vector mode
