3.
Choose which of the following is incorrect statement for vector-drawn images and bitmaps.
Correct Answer
C. Bitmaps are easily scalable and resizable
Explanation
The given statement "bitmaps are easily scalable and resizable" is incorrect. Bitmap images are made up of a grid of pixels, and when they are resized or scaled up, the individual pixels become more visible, resulting in a loss of image quality. Vector images, on the other hand, are made up of mathematical equations and can be scaled and resized without any loss of quality.
4.
The model is based on the light-absorbing quality of ink printed on paper
Correct Answer
C. CMYK
Explanation
CMYK stands for Cyan, Magenta, Yellow, and Key (black). It is a color model used in printing, where different amounts of these four colors are combined to create a wide range of colors. In this model, the ink absorbs light, with more ink resulting in less light being reflected. This is why CMYK is the correct answer, as it is specifically designed for printing on paper and takes into account the light-absorbing quality of ink. RGB, HSL, and HSB are color models used for digital displays and do not consider the ink absorption on paper.
5.
Ln 3-D process, graphics that can be applied to the faces of an object to provide a more realistic appearance are ?
Correct Answer
D. Textures
Explanation
In 3-D process, textures can be applied to the faces of an object to provide a more realistic appearance. Textures add visual details and surface qualities to the object, such as patterns, colors, and materials. This helps to enhance the overall realism of the object by giving it depth and texture, making it look more like a real-world object. Primitives, extrudes, and lathes are not specifically related to adding visual details or textures to the faces of an object in the 3-D process.
6.
A special effect in which one image seems to melt into another is referred to as?
Correct Answer
B. Morphing
Explanation
Morphing refers to a special effect where one image smoothly transitions or transforms into another. It involves blending and manipulating the pixels of two or more images to create a seamless transition between them. This effect is commonly used in movies, animations, and digital art to create visually stunning and smooth transitions between different objects or characters. Shearing, scaling, and distorting are different image manipulation techniques that do not specifically involve the smooth transition between images as in morphing.
7.
Lmages that are made up of thousands of pixels are called?
Correct Answer
A. Bitmap
Explanation
Images that are made up of thousands of pixels are called bitmaps. Bitmap images are made up of a grid of individual pixels, each with its own color value. This allows for detailed and realistic images, but can also result in larger file sizes compared to vector images. Bitmap images are commonly used for photographs and complex graphics.
8.
Panoramic images are created by stitching together a sequence of photos around a circle and adjusting them into a single seamless bitmap, true or false?
Correct Answer
A. True
Explanation
Panoramic images are indeed created by stitching together a sequence of photos around a circle and adjusting them into a single seamless bitmap. This process allows for a wider field of view, capturing a larger scene than what can be captured in a single photo. By aligning and blending the photos together, a panoramic image is created that provides a continuous and immersive view of the surroundings. Therefore, the given answer, "True," is correct.
9.

D. Modelling --> Animation --> Rendering
Explanation
The correct basic steps involved in creating 3D animation are modeling, animation, and rendering. Modeling is the process of creating the 3D objects and characters that will be used in the animation. Animation involves bringing these objects and characters to life by adding movement and actions. Finally, rendering is the process of generating the final visual output of the animation, which includes adding lighting, textures, and other visual effects.
10.
Identify which of the following answers refers to the statement.
Correct Answer
B. Subtractive color
Explanation
Subtractive color refers to the process of creating colors by subtracting certain wavelengths of light from the visible spectrum. This is commonly used in printing and mixing pigments, where the colors are created by absorbing or subtracting certain colors of light. Unlike additive color, which involves combining different colors of light to create new colors, subtractive color works by subtracting colors from white light to create the desired color. Therefore, subtractive color is the correct answer in this context.
11.
Which of the following best describes additive colour?
Correct Answer
B. Colour created combining coloured light sources in three primary colours; red, green and blue (RGB).
Explanation
Additive color refers to the process of creating color by combining different colored light sources. In this case, the primary colors used for additive color are red, green, and blue (RGB). When these three primary colors are combined at full intensity, they create white light. This is the basis for how colors are displayed on electronic screens such as televisions and computer monitors, where pixels emit different intensities of red, green, and blue light to create a wide range of colors.

Printing is a process for reproducing text and images using a master form or template. Modern printing is done typically with ink on paper using a printing press. It is also frequently done on metals, plastics, cloth and composite materials. On paper it is often carried out as a large-scale industrial process and is an essential part of publishing and transaction printing. Why vector drawing is most likely to be used in this field?
Correct Answer
C. It can be scaled at any sizes
Explanation
Vector drawing is most likely to be used in the field of printing because it can be scaled at any sizes. This is important in printing as the design needs to be reproduced accurately and consistently across different sizes and formats. Vector graphics are resolution-independent, meaning they can be scaled up or down without losing any quality or clarity. This makes them ideal for creating high-quality prints that maintain their sharpness and detail regardless of the size. Additionally, vector drawings are also versatile and can be used for complex and detailed designs, further enhancing their suitability for the printing industry.
13.
Which of the following software is used to create vector graphics?
Correct Answer
D. Adobe Illustrator
Explanation
Adobe Illustrator is the correct answer because it is a software specifically designed for creating vector graphics. Unlike raster graphics, vector graphics are composed of mathematical equations and can be scaled to any size without losing quality. Adobe Illustrator provides tools and features that allow users to create and edit vector-based images, illustrations, and designs. It is widely used by graphic designers, artists, and illustrators for creating logos, icons, typography, and other types of vector artwork.
14.
Bitmap images is also known as ____________ graphics.
Correct Answer
D. Paint
Explanation
Bitmap images are also known as "paint" graphics because they are created by painting individual pixels on a canvas. Each pixel in a bitmap image contains information about its color and position, and when combined, these pixels form the complete image. The term "paint" is commonly used to describe the process of creating or editing bitmap images using software tools that simulate traditional painting techniques.
15.
What are the colours represented by a charged-coupled-device (CCD) in a video camera?
Correct Answer
B. RGB
Explanation
A charged-coupled device (CCD) in a video camera represents colours using the RGB system. RGB stands for red, green, and blue, which are the primary colours used to create a wide range of other colours. By combining different intensities of red, green, and blue, the CCD captures and reproduces the full spectrum of colours seen by the camera. This allows for accurate and vibrant colour representation in the recorded video footage.
16.
Which of the following is not a colour model?
Correct Answer
D. CMYK, RGB, YUV, HLS
Explanation
The answer is CMYK, RGB, YUV, HLS. This is because CMYK, RGB, YUV, and HLS are all color models used to represent colors in different ways. CMYK is a subtractive color model used in printing, RGB is an additive color model used in digital displays, YUV is a color model used in analog television, and HLS is a color model that represents colors based on their hue, lightness, and saturation. Therefore, the correct answer is the option that does not include a color model, which is CMYK, CIE, YIQ, YCC.
17.
Dithering is a process whereby the color value of each pixel is changed to the closest matching color value in the target palette. This is done using colour coded algorithm.
Correct Answer
B. False
Explanation
Dithering is a process used to simulate colors that are not available in a limited color palette by using patterns of dots or pixels. It does not involve changing the color value of each pixel to the closest matching color value in the target palette. Therefore, the statement is false.
18.
_________ contains various shades of grey as well as pure black and white images.
Correct Answer
A. Grayscale image
Explanation
A grayscale image contains various shades of grey, ranging from pure black to pure white. It does not have any other colors. This is different from a black and white image, which only consists of pure black and pure white with no shades of grey. Grayscale images are commonly used in photography and digital imaging to represent a range of tones and create a more realistic representation of the original scene.
19.
In RGB color scheme, mixing red, green and blue will produce the color?
Correct Answer
B. White
Explanation
In the RGB color scheme, mixing red, green, and blue at their maximum intensity will produce white. This is because the RGB color model is an additive color model, where different intensities of red, green, and blue light are combined to create various colors. When all three primary colors are mixed at their maximum intensity, they create white light.
