The graphic board control is similar to the built-in drawing in windows.ProgramThe winform control is built based on the GDI + technology. With this control, we can quickly implement functions such as a tablet and a network whiteboard.
1. Supported shapes
(1) line segments, arrow lines, and double arrow lines
(2) horizontal elbow connector and vertical elbow connector
(3) rectangle, triangle, and elliptic (circle)
(4) Text
(5) Free Curve
(6) Insert a bitmap
The graphic board control adopts a plug-in-like implementation method, which allows you to conveniently add new shapes as needed.
2. Functions
(1) horizontal and vertical alignment
(2) Copying objects
(3) drag to change the shape and modify the object attributes (line width, color, fill color, Font, and actual line)
(4) cascade settings
(5) Scaling
(6) Laser pens
(7) print preview and print (horizontal and vertical)
(8) save as a bitmap
(9) A project can contain multiple pages, add pages, and delete pages.
(10) Save the project as a *. pf File
3. Network Interface
The graphic board control reserves a network interface. If the application can provide network communication, the content of multiple graphic boards can be synchronized, which is the core function of the network whiteboard.
The following figure shows the demo running of the graphic board control:
