Vector and raster i,ages

What is a bitmap image?

• An image made up of paths defined by mathematical equations

• An image that can be resized without losing quality

• An image made up of pixels

• An image that is always in black and white

What is a vector image?

• An image made up of pixels

• An image made up of paths defined by mathematical equations

• An image with a fixed resolution

• An image that cannot be resized

This type of image is created using pixels

What happens when you enlarge a bitmap image?

• It becomes clearer

• It remains the same quality

• It becomes pixelated

• It changes to a vector image

What is one advantage of vector images over bitmap images?

• They are always smaller in file size

• They can be resized without losing quality

• They support more colours

• They are easier to create

Which of the following is true about bitmap images?

• They are resolution-independent

• They are best for photographs

• They are always smaller in file size than vector images

• They cannot display gradients

An image made up of paths defined by mathematical equations

Match the following

• Shows bit pattern related to each colour

• • Pixelated

• An image that uses only two colors

• Vector image

• An image composed of pixels

• 1-bit image

• An image made from shapes, lines, curves

• Colour map

• • An image that appears blocky

• Bitmap image

Tick two of the following methods that will result in higher quality images

• shows how bit pattern relates to colours

• Using a higher resolution

• Image that appears blocky

• Using a higher bit depth

draw the following bit pattern on the grid
