Modern graphic editors allow you to create all kinds of images and drawings, as well as edit and view them. In order for a picture to be able to perform any action, it must be presented in digital form. To implement this process, there are two main ways. The simplest of them implies that each pixel is described separately. That is, each point is given a specific color. Images processed in this way are called raster images. In this form, as a rule, photographs, pictures with a large number of colors and paintings are presented. Many operating systems contain free graphic editors of this type.
A good example of raster graphics is the Paint application in the Windows operating system. As for paid analogues, there are currently no Adobe Photoshop equal programs. Raster graphic editors are considered the best tool for successfully working with scanned images and digital photographs. This is due primarily to the fact that it is quite possible to achieve better picture quality by changing the color palette. If necessary, you can increase the contrast and brightness, eliminate minor image defects. The user is given complete freedom of creativity using all kinds of effects.
However, drawing from scratch is not an easy task. Therefore, over time, vector graphic editors were developed that use objects as various lines and shapes as the main elements. The description is due to mathematical formulas. For example, to display a segment of a straight line, you need to specify only the coordinates of the start and end points, as well as color and thickness. In the case of raster graphics, all points would have to be indicated up to one, and with a larger thickness the number of pixels would increase significantly. From all this it follows that raster graphic editors have a rather voluminous general description, which in some situations is completely unnecessary.
Creating pictures from scratch is much more convenient in vector graphics applications when you need to depict a drawing, diagram or drawing without smooth color transitions. However, working with photographs or paintings in this case is still not worth it. Scaling has almost no negative effect on the quality of a
vector image . Thus, graphic editors of vector graphics are able to create images that are undemanding to zoom.
The leading position among such developments belongs to the program CorelDRAW, although at present there are a large number of other software tools of this type. The choice of a suitable editor should be carried out depending on the task, then serious difficulties in the work should not arise.
