Bitmap Images for KS3 Pupils

What is a bitmap image?

• An image created by a sequence of lines and curves

• An image made up of pixels, each with a fixed color

• A 3D model made up of polygons

• A vector graphic that scales without losing quality

Which file format is NOT typically associated with bitmap images?

• JPEG

• PNG

• SVG

• BMP

What happens when you zoom in on a bitmap image?

• The image becomes clearer

• The image remains the same

• The image may appear pixelated or blurry

• The image automatically enhances

How does the color of each pixel in a bitmap image get determined?

• By the distance from the center of the image

• By a color palette that is applied uniformly across the image

• Each pixel is assigned a color value based on its coordinates

• Each pixel has its own color value defined by a combination of red, green, and blue (RGB)

What is the main disadvantage of bitmap images compared to vector graphics?

• They can store more detailed images

• They take up less storage space

• They lose quality when scaled up

• They are easier to edit

Which tool would you use to edit a bitmap image?

• A text editor

• A vector graphics editor

• A bitmap image editor like Adobe Photoshop

• A 3D modeling software

What does the term "resolution" refer to in the context of bitmap images?

• The size of the image file

• The dimensions of the image in pixels

• The intensity of the colors in the image

• The physical size of the image when printed

Why might you choose a bitmap image over a vector graphic for a project?

• If you need an image that scales without loss of quality

• If you are creating a logo that uses geometric shapes

• If you are working with digital photographs

• If you require an image with a small file size

What is the effect of increasing the bit depth of a bitmap image?

• Decreases the file size

• Increases the number of colors that can be displayed

• Makes the image easier to edit

• Reduces the resolution of the image

How can the file size of a bitmap image be reduced without changing its dimensions?

• By increasing the resolution

• By converting it to a vector graphic

• By reducing the bit depth

• By cropping the image
