Résumé
A vector graphic editor is a computer program that allows users to compose and edit vector graphic s interactively on a computer and save them in one of many popular vector graphic formats, such as EPS, PDF, , SVG, or VML.
Vector editors are often contrasted with bitmap editors, and their capabilities complement each other. Vector editors are often better for page layout, typography, logos, sharp-edged artistic illustrations (e.g. cartoons, clip art, complex geometric patterns), technical illustrations, diagramming and flowcharting. Bitmap editors are more suitable for retouching, photo processing, photorealistic illustrations, collage, and illustrations drawn by hand with a pen tablet. Recent versions of bitmap editors such as GIMP and Adobe Photoshop support vector tools (e.g. editable paths), and vector editors such as Adobe Fireworks, Adobe FreeHand, Adobe Illustrator, Affinity Designer, Animatron, Artboard, Autodesk Graphic (formerly ), CorelDRAW, Sketch, Inkscape, sK1 or Xara Photo & Graphic Designer have adopted raster effects that were once limited to bitmap editors (e.g. blurring).
Some vector editors support animation, while others (e.g. Adobe Flash, Animatron or Synfig Studio) are specifically geared towards producing animated graphics. Generally, vector graphics are more suitable for animation, though there are raster-based animation tools as well.
Vector editors are closely related to desktop publishing software such as Adobe InDesign or Scribus, which also usually include some vector drawing tools (usually less powerful than those in standalone vector editors).
Special vector editors are used for computer-aided drafting. These are not suitable for artistic or decorative graphics, but are rich in tools and object libraries used to ensure precision and standards compliance of drawings and blueprints.
Finally, 3D computer graphics software such as Maya, Blender or Autodesk 3ds Max can also be thought of as an extension of the traditional 2D vector editors, as they share some common concepts and tools.

Adobe Illustrator
Adobe Illustrator est un logiciel de . Il fait partie de la gamme Adobe, peut être utilisé indépendamment ou en complément de Photoshop, et offre des outils de dessin vectoriel puissants. Les images vectorielles sont constituées de courbes générées par des formules mathématiques. L'un des outils principaux d'Illustrator étant « la plume » qui permet de tracer des courbes à l'aspect parfait grâce au placement de points d'ancrage et de tangentes qui vont en modifier la courbure.
Comparison of vector graphics editors
A number of vector graphics editors exist for various platforms. Potential users of these editors will make a comparison of vector graphics editors based on factors such as the availability for the user's platform, the software license, the feature set, the merits of the user interface (UI) and the focus of the program. Some programs are more suitable for artistic work while others are better for technical drawings. Another important factor is the application's support of various vector and bitmap image formats for import and export.
CorelDRAW
CorelDRAW est une suite graphique développée par l'éditeur de logiciels Corel depuis 1989. À l'origine, il s'agissait du logiciel de dessin vectoriel CorelDRAW. Au fil du temps, d'autres logiciels tels que Corel PhotoPaint et Corel R.A.V.E ont été ajoutés et le logiciel est devenu une suite graphique. Le nom initial est CorelDRAW, mais depuis la version 11, la suite s'appelle CorelDRAW Graphics Suite. La dernière version s'appelle CorelDRAW Graphics Suite 2018 et correspond à la version 20.
