Adobe Illustrator is a vector graphics editor developed and marketed by Adobe Inc. Adobe Illustrator is the companion product of Adobe Photoshop. Photoshop is primarily geared toward digital photo manipulation and photorealistic styles of computer illustration, while Illustrator provides results in the typesetting and logo graphic areas of design. While Adobe Photoshop works on pixels, Illustrator is based on vectors.
There is a range of tools on the platform. A sidebar that appears at the left of the screen shows the tools to select, create, and manipulate objects or artworks in Illustrator. These tools can be selected as following: drawing, typing, painting, reshaping, slicing and cutting, symbolism, moving and zooming, and graph. Some tools have a small triangle at the bottom right of the toolbox icon. A small triangle has the option to view or expand some hidden tools by hold down the mouse button on the triangle.
Some examples of basic tools in Illustrator are selection tools, paintbrush tools, pen tools, pencil tools e.g. Selection tools are used to the layout, adjust, and organize the artwork by selecting, positioning, and stacking object accurately. Moreover, selection tools can group, lock or hide, and measure objects. Paintbrush tools can be used to modify the appearance of the artwork. There are different types of brushes: calligraphic, scatter, art, pattern, and bristle. Pen tools create straight and curved lines for the artwork and they can add anchor points to paths and delete from paths. Pencil tools allow the user to draw and edit freehand lines.
