What are the two types of images?
Vector and Raster or pixel images.
What are two types of image management programs?
There are two types of images you can work with, vector images and pixel(raster or bitmap images).Vector based software are Adobe Illustrator, CorelDraw and you can work both image types, but you have more capabilities to work with vector images, primer for pixel based software is Photoshop in which you can also work with both image types but you have more capabilities to work with pixel images.
What does Vector and Bitmap mean?
Vector and bitmap are both image files. Bitmapped images are images that are stored on a pixel by pixel basis and because of this, when you enlarge the image it can appear blocky. A vector image is constructed from dots, lines, shapes, etc. Each part has a particular position within the image with it's own dimensions. Because vector images are constructed using images, they can be enlarged without loss of image quality. Vector images do not get the blocky appearance of an enlarged bitmap image.
Graphic images where each pixel is bit-mapped and take up more memory?
Graphic images where each pixel is bit-mapped and take up more memory?

What are graphic images where each pixel is bit-mapped?
The bitmapped graphics file is a .bmp file.
Do vector-based images usually require less memory than bitmap images?
Yes - for simple images like drawings, because they describe how to generate the image and do not store each pixel apart.
Capabilities and limitations of Vector Images?
capabilities Vector images use less memory space and have a smaller file size. For the web, pages that use vector graphics in plug-ins download faster, and when used for animation, draw faster. the ability to scale the image to any size without loss of quality limitation Vector images, however, cannot reproduce 'continuous tone photographic images like bitmaps vector images cannot be used for photorealistic images. Vector images require a plug-in for web-based display.
What is the differeance between Rasta and vector?
Raster images are defined in pixels. ie At every x,y location, whether it is black or white. Vector images are defined by lines. eg From x,y to X,Y. Any pixel that lies between these points on a white background becomes black. It is easier to convert Vector images to Raster images, rather than the other way. Vector images are sometimes smaller (in data size). eg If the image contains one line, then the amount of data needed to store this is smaller than having to define every pixel in the image regardless of whether it is relevant. Vector images can be scaled smaller and larger without any significant loss of detail. Raster images that have been made smaller lose clarity and cannot then be made larger to improve the quality.
What is Vector tracing?
Vector tracing, also known as vectorization, is the process of converting raster images or bitmap graphics into vector graphics. Raster images are composed of a grid of pixels, where each pixel contains color information, and they are resolution-dependent. This means that when you enlarge a raster image, the pixels become visible, resulting in a loss of quality and a pixelated appearance.
Graphic images defined by geometric shapes each of which can define the attributes of many pixels These use less memory?
Vector graphics use less memory as they describe (in mathematical terms) shapes rather than the color and position of each pixel in an image.
Bitmaps must be greater than one pixel on a side?
Yes; less than one pixel is 0 pixels which is nothing = no image Vector images can be of any size but when rendered to screen (or any imaging device which uses pixels) of course the result must be at least 1 pixel for the object to appear. The vector object might very well be there but be invisible due to the (low) resolution of the imaging output.
