It is mainly divided into two categories:
Digital drawing board:
Digital drawing board usually consists of a board and a pressure-sensitive pen, like A painter's drawing board and brush, but this is a digital product and needs to be connected to a computer and used with software.
The digital drawing board allows you to regain the feeling of holding a pen to draw on paper. It can simulate a variety of painters' brushes, such as simulating the most common brush. When we use force, the brush It can draw very thick lines. When we use very light force, it can draw very thin and light lines. It can simulate an airbrush. When you use more force, it can spray more ink and a wider range. , and can also spray out fan-shaped effects according to the tilt angle of your pen... In addition to simulating various traditional brush effects, it can also take advantage of the computer to create effects that cannot be achieved using traditional tools, such as Paint the pattern according to the amount of pressure. You can easily draw a field full of flowers of different sizes and shapes with just a few strokes...
The main parameters of the digital drawing board There are sensing technology, pressure sensitivity level, writing method, personalized shape and recognition rate, among which pressure sensitivity level is the key parameter. Information such as brushes with different pressure sensitivity levels and different stroke strengths are fed back to the computer through the digital drawing board and digital pen, thereby forming stroke effects of different thicknesses. Draw works with different effects. As a hardware input tool, the digital drawing board, combined with drawing software such as Painter and Photoshop, can create works of various styles: oil paintings, watercolors, sketches, polypropylene... You must know that using a digital wand and a pressure-sensitive pen, combined with Painter and Photoshop software can simulate a variety of brushstrokes.
System drawing board:
The drawing board that comes with the Windows system is simple and clever, and is deeply loved by Windows users. It takes up less resources, is simple to operate, and has complete functions. It brings a lot of convenience for small graphics development work. For this reason, many drawing boards that imitate Windows have appeared using visual development tools such as VC. This chapter completely uses C language to develop a drawing board, which has basic drawing board functions such as drawing, adjusting the size and orientation of graphics, saving and opening files, etc.
