Think of all those digital cameras out there pumping out JPG and PNG images - converting those over to vector is hit and miss. However, creating vector images can be a fussy process and the 'industry standard' is still raster. This process occurs dozens of times every second to create a smooth moving image.ДЄpril 10, - the solution is use vector graphics which can be scaled up or down as much as needed. When the beam that is drawing the image reaches the bottom right corner of the screen, effectively indicating the whole image was rendered, it moves back to the upper left corner to start again, an action known as a vertical retrace. The line returns to the left side, dropping a tiny amount downward, and draws the next line of the image. In a television or computer monitor, an image is constructed using raster scan technology by starting in the upper left-hand corner of the screen and drawing a horizontal line that ends on the right edge of the screen. One of the primary applications of raster scaning technology has been in traditional display devices such as televisions. Most digital images files also are stored and reconstructed using raster scan techniques. Some computerized printers also use similar methods to construct images on paper. One of the primary applications of raster scaning technology has been in traditional display devices such as televisions or computer monitors. The lines can be analog representations of the image, or they can be a sequence of pixels in which each dot represents a tiny rectangular area of the image. A raster scan is a method of constructing an image through the use of horizontal lines.
