Hello students this page provides you with Computer Graphics MCQ-2
Q.1 The quantity of an image depend on?
No. of pixel used by image
No. of line used by image
No. of resolution used by image
None of these
Explanation
The level of detail and quality (often referred to as ‘quantity’ of data) in a digital image is primarily determined by the number of pixels it contains.
Q.2 If the magnitude of the curve slope is lesser than 1, then:
We can plot horizontal spans
We can plot vertical spans
Only (b)
All of the mentioned
Explanation
In scan conversion algorithms, the slope of the curve or line determines whether the algorithm steps through horizontal or vertical coordinates to plot the path accurately.
Q.3 The process of determining the appropriate pixels for representing picture or graphics object is called as?
Scan conversion
Rasterization
both A & B
All of the mentioned
Explanation
Rasterization is the task of taking an image described in a vector graphics format and converting it into a raster image (pixels).
Q.4 The process of discrete pixels is known as?
Scan conversion
Rasterization
both A & B
All of the mentioned
Explanation
Scan conversion is the process of representing continuous graphics objects as a collection of discrete pixels.
Q.5 Higher the number of pixels—– the image quality?
Bad
Better
Smaller
None of these
Explanation
A higher pixel count increases the resolution, which leads to a sharper, more detailed, and overall better image quality.
Q.6 One of the methods for displaying thick curve.
Curve slope
Curve width
Curve cap
Only (c)
Explanation
The slope of the curve can be used in certain algorithms to determine the offset and thickness required to render a thick line or curve.
Q.7 The picture is produced on the monitor and the user does not have any change on this picture is known as?
Interactive
Non Interactive
Passive
Both B & C
Explanation
Non-interactive graphics (also called passive graphics) are those where the observer has no control over the image; it is purely for viewing.
Q.8 The picture is produced on the monitor and the user can change is known as?
Interactive
Non Interactive
Passive
Both A & B
Explanation
Interactive computer graphics involve two-way communication between the computer and the user, allowing the user to control or modify the image.
Q.9 A palette can be defined as a finite set of colors for managing the?
Analog images
Digital images
Both A & B
None of these
Explanation
In digital imaging, a palette (or color lookup table) is a limited set of colors used to display an image efficiently.
Q.10 Which one is the rigid body transformation that moves object without deformation?
Translation
Scaling
Rotation
Shearing
Explanation
Translation moves every point of a figure or a space by the same distance in a given direction, preserving its shape and size.
Q.11 TV Show is an example of?
Interactive
Non Interactive
Both A & B
None of these
Explanation
A standard TV show is non-interactive because the viewer cannot change the content or the sequence of the images being broadcast.
Q.12 Display card are?
VGA
EGA
Both A & B
None of these
Explanation
VGA (Video Graphics Array) and EGA (Enhanced Graphics Adapter) are both types of graphics display standards/cards.
Q.13 Ping-Pong Game is an example of?
Interactive
Non Interactive
Passive
None of these
Explanation
Video games like Ping-Pong are interactive because the player provides input that changes the state and appearance of the graphics in real-time.
Q.14 An ellipse can also be rotated about its co-ordinates by rotating?
End points
Major and minor axis
Only (a)
None
Explanation
Rotating the major and minor axes of an ellipse effectively changes its orientation in a 2D coordinate system.
Q.15 Which of the following is not a line-type?
Dashed line
Dark line
Dotted line
Only (b)
Explanation
Standard line attributes in computer graphics include solid, dashed, and dotted; ‘Dark’ refers to color or intensity rather than the geometric line type.
Q.16 Several graphics image file formats that are used by most of graphics system are?
GIF
JPEG
TIFF
All of These
Explanation
GIF, JPEG, and TIFF are all widely used standard file formats for storing and exchanging graphical images.
Q.17 PPI Stands for?
Pixels per inch
Pixels per input
Pixels put in
None of these
Explanation
PPI (Pixels Per Inch) is a measurement used to define the resolution of a digital display or an image.
Q.18 GIF Stands for?
Graphics interchange fill
Graphics input format
Graphics interchange format
None of these
Explanation
GIF stands for Graphics Interchange Format, a bitmap image format developed by CompuServe in 1987.
Q.19 The GIF format is much —— to be downloaded or uploaded over the www.?
Faster
Slower
Medium
None of these
Explanation
Because GIF files use efficient compression and a limited color palette (up to 256 colors), they result in smaller file sizes that are faster to transfer online.
Q.20 Pixel mask means:
A string containing only 1's
A string containing only 0's
A string containing 1 and 0
A string containing only 0 and 1.
Explanation
A pixel mask (or bitmask) is a string of binary digits (1s and 0s) used to determine which pixels should be modified or displayed during a drawing operation.
