### A vector graphic uses a matrix of many dots or pixels to define the image.

• A.

True

• B.

False

B. False
Explanation
A vector graphic does not use a matrix of dots or pixels to define the image. Instead, it uses mathematical equations and geometric shapes to create the image. This allows the image to be scaled without losing quality, as it is not dependent on a fixed number of pixels.

### If we have transparency in our image, we should save in which format?

• A.

JPG

• B.

PNG

B. PNG
Explanation
If we have transparency in our image, we should save it in the PNG format. Unlike JPEG, PNG supports transparency and can preserve the alpha channel, allowing for images with transparent backgrounds or layered images to be saved without losing any information. This makes PNG the preferred format for images that require transparency, such as logos, icons, or images with complex backgrounds.

### Which type of image can be enlarged without losing quality?

• A.

Bitmap (.PNG for example)

• B.

Vector (.AI for example)

B. Vector (.AI for example)
Explanation
Vector images can be enlarged without losing quality because they are created using mathematical equations and geometric shapes rather than pixels. This means that when a vector image is scaled up, the equations and shapes are recalculated to maintain the smoothness and clarity of the image. On the other hand, bitmap images, such as PNG, are made up of a fixed number of pixels, and when they are enlarged, the pixels are stretched, resulting in a loss of quality and pixelation.

### Which keyboard shortcut do we use to un-do a mistake?

• A.

F5

• B.

F6

• C.

Ctrl-Z

• D.

Ctrl-Enter

C. Ctrl-Z
Explanation
To undo a mistake, we use the keyboard shortcut Ctrl-Z. This shortcut is commonly used in various software applications to reverse the most recent action or undo the last change made. By pressing Ctrl-Z, we can easily revert back to the previous state before the mistake, saving time and effort in correcting errors. F5 and F6 are function keys that typically have different functions depending on the software being used, while Ctrl-Enter is often used to execute a command or insert a line break.

### What do we mean by the "z-dimension?"

• A.

Left and right

• B.

Up and down

• C.

Into and out of the page

C. Into and out of the page
Explanation
The "z-dimension" refers to the third dimension in a three-dimensional coordinate system. It represents depth or the direction into and out of the page. In a two-dimensional space, we have the x-dimension for left and right movement and the y-dimension for up and down movement. However, in a three-dimensional space, we introduce the z-dimension to describe movement into and out of the page.

### How many dimensions can we work in when making animations?

• A.

1

• B.

2

• C.

3

• D.

4

D. 4
Explanation
When making animations, we can work in four dimensions. This means that we can manipulate objects in terms of their position in three-dimensional space (x, y, and z axes) as well as their movement over time (the fourth dimension). By utilizing these four dimensions, animators can create more realistic and dynamic animations with depth, perspective, and fluid motion.

### To create a vector graphic in Flash, you draw on the:

• A.

Timeline

• B.

Library of symbols

• C.

Scene

• D.

Properties panel

C. Scene
Explanation
To create a vector graphic in Flash, you draw on the scene. The scene is where you can create and edit the elements of your animation, including vector graphics. The timeline is used to organize and control the animation sequence, the library of symbols is where you store and manage reusable elements, and the properties panel is used to modify the properties of selected elements. However, for creating vector graphics specifically, the scene is the appropriate place to draw and edit them.

### To create the sequence of a movie, different frames are placed along the:

• A.

Timeline

• B.

Library

• C.

Scene

• D.

Properties panel

A. Timeline
Explanation
In order to create the sequence of a movie, different frames are placed along the timeline. The timeline is a visual representation of the movie's progression, showing the order and duration of each frame. By placing frames along the timeline, the movie's sequence is established, allowing for smooth playback and storytelling. The timeline provides a clear structure for organizing and editing the frames, ensuring that the movie flows seamlessly from one scene to the next.

### The parameters of the objects can be modified in the:

• A.

Timeline

• B.

Library

• C.

Scene

• D.

Properties panel

D. Properties panel
Explanation
The properties panel is where the parameters of objects can be modified. This panel allows users to adjust various attributes and settings of objects such as size, position, color, and opacity. It provides a convenient and centralized location for making changes to objects within a software or design tool. The timeline, library, and scene may have their own functions and options, but they are not specifically designed for modifying object parameters.

### To extend the content of a tween (interpolacion), without making changes, you should insert a:

• A.

Frame

• B.

Keyframe

• C.

Blank keyframe

• D.

Symbol

A. Frame
Explanation
To extend the content of a tween without making changes, you should insert a frame. This means that you can add more time to the tween without altering the content or properties of the animation. By inserting a frame, you are essentially prolonging the duration of the tween without any modifications to the visual elements or animations within it.
