    A raster image is:

    • A compression formula originally developed by CompuServe and are based on indexed colors

    • Artwork that is composed of mathematical descriptions of a series of lines and geometric shapes

    • The color “space” or document type which is defined by black and white plus all of the gray tones as well

    • A grid of individual bits in rows and columns called a bitmap

    Correct Answer
    A. A grid of individual bits in rows and columns called a bitmap
    Explanation
    A raster image is a grid of individual bits in rows and columns called a bitmap. This means that the image is made up of a series of pixels, each represented by a bit, arranged in a grid-like structure. Raster images are commonly used for representing photographs and complex graphics, as they can accurately capture the details and colors of the original image. They are different from vector images, which are composed of mathematical descriptions of lines and shapes. Raster images are also often associated with specific color spaces or document types, including black and white and various shades of gray.

    • A color producing mode using “additive primaries” because the light of the monitor display is added together to make a color you need

    • A way to describe documents containing any combination of text, graphics, and images in a device-independent and resolution independent format

    • The process of combining any two or more objects

    Correct Answer
    A. The color “space” or document type which is based on the absorption and reflection of light
    Explanation
    CMYK stands for the color "space" or document type which is based on the absorption and reflection of light. This color model is used in printing and refers to the four ink colors used: cyan, magenta, yellow, and key (black). By combining different percentages of these colors, a wide range of colors can be achieved. Unlike RGB, which is an additive color model used for electronic displays, CMYK is a subtractive color model where the colors are subtracted from white light to create the desired color. This is why CMYK is commonly used in printing, as it accurately represents the absorption and reflection of light on paper.
