  • 3. 

    Which is more useful in situations where image compression involved solid colors repeating often?

    • A.

      Lossless

    • B.

      Lossy

    • C.

      Neither

    • D.

      Both

    Correct Answer
    A. Lossless
    Explanation
    In situations where image compression involves solid colors repeating often, lossless compression would be more useful. Lossless compression algorithms are designed to preserve all the original data and ensure that there is no loss in quality. This would be beneficial in scenarios where solid colors are repeated often because lossy compression, which involves discarding some data to achieve higher compression ratios, may result in a loss of detail and introduce artifacts in the image. By using lossless compression, the image can be compressed without sacrificing any quality, making it more suitable for situations where solid colors are repeated frequently.

    Rate this question:

  • 20. 

    Pixels determine the size of the image in __________ images.

    • A.

      Bitmap

    • B.

      Vector

    • C.

      Both

    • D.

      Neither

    Correct Answer
    A. Bitmap
    Explanation
    Pixels determine the size of the image in bitmap images. Bitmap images are made up of individual pixels, and the size of the image is determined by the number of pixels it contains. Each pixel represents a single point in the image and contains information about its color and brightness. Therefore, the more pixels an image has, the higher its resolution and the larger its size. Vector images, on the other hand, are not made up of pixels and can be resized without losing quality.

    What is rasterizing?

    • A.

      Transforming bitmap to vector

    • B.

      Transforming vector to bitmap

    • C.

      Transforming SVG to JPG

    • D.

      Transforming JPG to SVG

    Correct Answer
    B. Transforming vector to bitmap
    Explanation
    Rasterizing refers to the process of converting vector graphics, which are made up of mathematical equations and lines, into a bitmap or raster image composed of pixels. This transformation is necessary when vector graphics need to be displayed on devices or platforms that only support raster images, such as computer screens or printers. By converting the vector graphics to a bitmap format, the image can be rendered accurately with each pixel representing a specific color or shade. Therefore, transforming vector graphics to a bitmap is the correct explanation for rasterizing.
