Vector- drawn: what is the meaning of " on the fly " in vector images? It means that computers draw the image as per instructions.

Transcription

1 Bitmaps: what is bit and map means? bit is the simplest element in the digital world. map is a two-dimensional matrix of these bits. Vector- drawn: what is the meaning of " on the fly " in vector images? It means that computers draw the image as per instructions. 3d: what is 3d representation? 3d represented for 3-dimensional image lies on x, y, and z planes there by providing an appearance that include width, height and depth. Clip Art: what are the three categories of clip art? 1.public domain images. 2.royalty-free images. 3.rights-managed images.

3 1- Define what is a Bitmap? Is a single matrix of the tiny dot that form an image and are displayed on a computer screen or printed. Bit: smallest element in the digital world Map: 2D matrix of these bits. 2- make comparison between Vector-drawn and bitmap? Vector image is draw by a computer as per instructions while bitmap it has to load the pre-created images, so vector image images are faster than bitmap images. 3- What is mean by 3D? Techniques which use 3 dimensional plans x, y, and z that provide appearance width, height, and depth. 4- List the type of clip art? Public domain image. Royalty. Right-managed images. 5- From what JPEG derive? Derive from "Joint Photographic Experts Group".

5 1- Where we can use Bitmaps? Bitmaps are used for photo-realistic images; complex drawing requiring fine details. 2- Who is faster Bitmap or Vector? And How? Vector is faster. Vector images are on the fly which means that computers draw the image as per instructions while with the bitmaps, it has to load the pre-created images. For this reason, the vector images are faster to load than bitmap images. 3- What does 3D include? 3D include width, height and depth. 4- What are the categories of clip art? Clip Art Libraries fall under three categories: 1- Public domain images no copyright or copyright has expired hence this can be used freely; 2- Royalty-free images are purchased and then used without paying additional license fee; 3- Rights-managed images these images requires negotiation with the rights holder regarding the terms for using the images and how much you need to pay. 5- What you know about Portable Network Graphics? is a raster graphics file format that supports lossless data compression. PNG was created as an improved, non-patented replacement for Graphics Interchange Format (GIF), and is the most used lossless image compression format on the Internet.

6 What is the bitmaps? A single matrix of the tiny dot that from an image and are displayed on a computer screen of printed What dose vector-drawn mean? A line that is described by the location of its two endpoint How make 3 dimensional images? About a collection that may contain a random assortment of images, or it may contain a series of graphics, photographic, sounds and videos related to a single topic. Clip art is? A collection that may contain a random assortment of images of or it may contain a series of graphics, photography, sounds and videos related to a single topic What are the categories of the clip art? -Public domain images no copyright has expired hence this can be used freely -Royalty free images are purchased and then used without paying additional license fee -Rights-managed images these images requires negotiation with the right holder regarding the terms for using the images and how much you need to pay

7 Name: boshra mohammed Abdullah al-sinani ID: Q1: what is a bitmaps and for what it used? Is a single matrix of the tiny dot that form an image and are displayed on a computer screen or printed. It used for photo-realistic images; complex drawing find details. Q2: write definition of vector-draw graphics, A vector and vector images. A vector: is a line that is described by the location of its two endpoint. vector images: are on the fly which means that computer drow the image as per instruction while with the bitmaps, it has to load the precreated images vector-draw graphics: are used for lines, boxes, circles, polygon and graphic shapes that can be expressed in angles, coordinates and distances. Q3: What is the 3 Dimensional? A3 Dimensional image lies on X, Y, Z planes thereby providing an appearance that include width, height and depth. Q4: what is the clip Art and what is its categories? the clip Art is a collection that may contain a random assortment of images. The categories are: 1- Public domain images 2- Royalty-free images 3- Rigts-managed images

8 Q5: Explain the EPS file format. Is one of Photoshop format and the EPS or Encapsulated postscript is a standard graphics files format for exchanging images, drawing(such as a logo or map) or even layouts of complete page. An EPS file internally contains a description of such an object or layout using the postscript page description language. The purpose of an EPS files is to be include in other page.
