Question

True or false? 1. Greyscale images take up more disk space than colour images. 2. It's often preferable to scan line drawings as black and white images rather than greyscale images. This takes up less disk space, and produces sharper lines. This type of image is also known as lineart. 3. On most computers, you can view photos as a slideshow – each photo is shown for a few seconds. 4. You can also view photos as fingernails – small versions of the photos, with lots shown on the screen at the same time. 5. A vector image (for example, a clipart image) can be expanded to any size without loss of solution. A bitmap image (for example, a photo) is made of pixels, so it loses resolution when it is expanded.

Answer 1

False, true, true, false(??), true

Answer 2

1. False. Greyscale images typically take up less disk space than color images because they only store shades of grey instead of separate color values for each pixel.

2. True. It is often preferable to scan line drawings as black and white images rather than greyscale images because it takes up less disk space and produces sharper lines. Black and white line drawings are also known as lineart.

3. True. On most computers, you can view photos as a slideshow where each photo is displayed for a few seconds before transitioning to the next.

4. True. You can also view photos as thumbnails or fingernails, which are small versions of the photos displayed in a grid layout on the screen. This allows for multiple photos to be shown at the same time.

5. True. A vector image, such as a clipart image, can be expanded to any size without loss of resolution. This is because vector images are based on mathematical equations and shapes, rather than pixels. On the other hand, a bitmap image, such as a photo, is made of pixels and will lose resolution when expanded beyond its original size.
