Computer Applications II Objective 1.02 Test B

• 1.

### Layering is

• A.

Adding transparency to an image.

• B.

Compiling multiple images together into one.

• C.

Filling a shape with gradient.

• D.

Rotating and cropping.

B. Compiling multiple images together into one.
Explanation
Layering is the process of compiling multiple images together into one. This technique involves placing different images on top of each other, creating a layered effect. Each layer can be edited individually, allowing for greater flexibility and control over the final composition. By combining multiple images, layering enables the creation of complex and visually appealing designs.

### ___ an image is pivoting it around its center point.

Rotate
Rotating
Explanation
The correct answer is "Rotate" or "Rotating". When we rotate an image, we pivot it around its center point. This means that the image is turned or twisted in a circular motion, causing it to change its orientation.

### Feathering is

• A.

Cropping parts of an image.

• B.

Anti aliasing an image.

• C.

Blurring the edges of an image to make them smoother.

• D.

Adding white space around an image.

C. Blurring the edges of an image to make them smoother.
Explanation
Feathering refers to the technique of blurring the edges of an image in order to make them smoother. This is often done to create a more seamless transition between the subject and the background, or to blend multiple images together. By blurring the edges, the image appears softer and more natural, without any harsh lines or abrupt transitions. This technique is commonly used in graphic design, photo editing, and digital art to achieve a more polished and professional look.

### ____ is removing parts of an image.

Cropping
Crop
Explanation
Cropping is the process of removing parts of an image. It involves selecting a specific area or portion of the image and discarding the rest. This can be done to eliminate unwanted elements, improve composition, or focus on a particular subject. "Crop" is a synonym of "cropping" and can be used interchangeably in this context. Both options accurately describe the action of removing parts of an image.

### ___ approximates and adds colors that aren't part of the original.

Dithering
Dither
Explanation
Dithering is a technique used in digital imaging to approximate and add colors that are not present in the original image. It works by using patterns of different colored pixels to create the illusion of additional colors and smooth gradients. This is especially useful in situations where the color palette is limited, such as in computer graphics or printing. Dithering helps to reduce banding and create a more visually appealing and accurate representation of the original image.

Rate this question:

• 6.

• A.

Filling an object with a texture.

• B.

Filling an object with a pattern.

• C.

Filling an object with a smooth transition of colors.

• D.

Filling an object with a single color.

C. Filling an object with a smooth transition of colors.
Explanation
The correct answer is "filling an object with a smooth transition of colors." A gradient is a gradual change in color from one hue to another, creating a smooth transition. It is commonly used in design to add depth and visual interest to objects or backgrounds. Unlike filling an object with a single color, a gradient adds variation and can create a sense of movement or dimension.

• 7.

### Is an example of ___.

dithering
Dithering
Dither
dither
Explanation
The correct answer is "dithering". Dithering refers to a technique used in computer graphics to create the illusion of colors or shades that are not available in a limited color palette. It involves the use of small dots or patterns of different colors to simulate the appearance of a broader range of colors or shades. Dithering helps to reduce banding and create smoother transitions between colors in images or graphics.

### True or False - Textures are used to create filters and backgrounds.

• A.

True

• B.

False

A. True
Explanation
Textures are indeed used to create filters and backgrounds. Textures are patterns or images that can be applied to surfaces in order to add visual interest and depth. In graphic design and digital art, textures are commonly used to create unique and visually appealing filters or to enhance the background of an image or design. By applying textures, designers can add texture and dimension to their work, creating a more realistic or artistic effect. Therefore, the statement "Textures are used to create filters and backgrounds" is true.

Rate this question:

• 9.

### Which one of the following is a filter?

• A.

Clone tool

• B.

Paintbrush

• C.

Cropping

• D.

Blur

D. Blur
Explanation
Blur is a filter because it is a tool or effect used to soften or smoothen an image, reducing the level of detail and creating a blurred or out-of-focus appearance. It is commonly used to enhance the overall aesthetics of an image or to draw attention to specific areas by blurring the surrounding background. Unlike the other options mentioned (Clone tool, Paintbrush, and Cropping), which are not specifically designed to alter the visual appearance of an image, Blur is a dedicated filter with a distinct purpose.

• 10.

### ___ is removing parts of an image so that the background is visible.

Explanation
The process of removing parts of an image to make the background visible is known as "image cropping".
