Vector Data
In computer graphics, vector data usually refers to a means of representing lines, polygons, or curves (or any object that can be easily drawn with lines) by numerically specifying key points. The job of a program rendering this key-point data is to regenerate the lines by somehow connecting the key points or by drawing using the key points for guidance. Always associated with vector data is attribute information (such as color and line thickness information) and a set of conventions (or rules) allowing a program to draw the desired objects. These conventions can be either implicit or explicit, and, although designed to accomplish the same goals, are generally different from program to program.
Bitmap Data
Bitmap data is formed from a set of numerical values specifying the colors of individual pixels or picture elements (pels). Pixels are dots of color arranged on a regular grid in a pattern representing the form to be displayed. We commonly say that a bitmap is an array of pixels, although a bitmap, technically, consists of an array of numerical values used to set, color, or "turn on" the corresponding pixels on an output device when the bitmap is rendered. If there is any ambiguity in the text, we will make the distinction clear by using the term pixel value to refer to a numerical value in the bitmap data corresponding to a pixel color in the image on the display device
- i generally used a vector sorcue of data while making my tshirt graphics as i used a varity of photos to layout a final display which consisted of a freehand approch to the task as for the oppiste applies to a bitmapn data formate.
the colours contrasting a shapes all used in the graphics show the effect of a vector database.
