Introduction to Image Editing 1 — Questions and Answers
Question 1: Which of the following terms refers to the movement of a "object" around a center point?
- Dithering
- Cropping
- Rotating (Correct answer)
- Moving
Correct answer: Rotating
Rotating refers to the action of turning an object around a fixed central point or axis. In image editing, this allows users to change the orientation of an entire image or a selected part of it. This transformation is essential for correcting crooked photos, adjusting composition, or creating dynamic visual effects by altering an object's angle.
Question 2: Which feature causes image edges to seem blurry?
- Cloning
- Cropping
- Feathering (Correct answer)
- Layering
Correct answer: Feathering
Feathering is a technique used in image editing to soften the edges of a selection or an object. It creates a gradual, blurred transition between the selected area and its surroundings, rather than a sharp, abrupt line. This effect is often used to blend elements seamlessly, create vignettes, or make selections appear less harsh.
Question 3: Which format should you use for a colorful shot of a rainbow?
- Rainbow.bmp
- Rainbow.jpg (Correct answer)
- Rainbow.png
- Rainbow.tiff
Correct answer: Rainbow.jpg
JPEG (.jpg) is the most suitable format for colorful photographic images like a rainbow due to its efficient lossy compression algorithm. It excels at representing continuous tones and complex color gradients with relatively small file sizes, making it ideal for web display and general photo storage. While some detail is lost, it's generally imperceptible in photos and offers a good balance of quality and file size.
Question 4: Which of the following terms applies to anything displayed on a page that is not true text?
- Clip art
- Charts
- Graphics (Correct answer)
- Icons
Correct answer: Graphics
Graphics is the general term that refers to anything displayed on a page that is not true text. This broad category includes images, illustrations, charts, icons, and clip art. Graphics are used to enhance visual communication, convey information, and add aesthetic appeal to documents and web pages.
Question 5: The W3C introduced which of the following vector file formats to establish a standard, adaptable format for vector drawings viewed on the web?
- CDR-Corel Draw
- DFX-Autocad
- SVG-Scalable Vector Graphics (Correct answer)
- WMF-Windows Metafile
Correct answer: SVG-Scalable Vector Graphics
The W3C introduced SVG (Scalable Vector Graphics) as an XML-based vector image format to establish a standard, adaptable format for vector drawings viewed on the web. SVG images are resolution-independent, meaning they can be scaled to any size without losing quality, and support interactivity and animation. This makes it an ideal format for web graphics that need to be flexible and accessible.
Question 6: What is another term for raster graphics?
- Pixel
- Paint
- Bitmap (Correct answer)
- Resolution
Correct answer: Bitmap
Raster graphics are also commonly known as bitmap graphics. This term highlights that these images are composed of a grid of individual pixels (picture elements), where each pixel contains specific color information. The quality and resolution of a raster image are fixed by the number of pixels it contains, making it resolution-dependent.
Question 7: Which graphic application would be chosen if the user wants to ensure that the visual maintained absolute resolution quality independent of size, enlarged or reduced?
- Raster
- Vector (Correct answer)
- Compression
- Color Depth
Correct answer: Vector
Vector graphics are the ideal choice when the user needs to ensure that the visual maintains absolute resolution quality independent of size. Unlike raster images, which are composed of pixels, vector graphics are made up of mathematical paths, points, and curves. This allows them to be scaled infinitely larger or smaller without any loss of clarity, sharpness, or detail.
