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