Adjust the space location of an object to break the completely symmetrical layout, strengthen the changing factors, and form a balanced diagram. Through the comparison of primary and secondary importance, we can find changes and enhance the aesthetic of the diagram.Figure 34. The screen is only "aggregated", but not "scattered", resulting in a sense of "squeeze. It is neces

called in the parent process to suspend the execution of the parent process and wait for the completion of the Child process. The PID of the child process is returned. If stat_loc is not a null pointer, the status information will be written to the location pointed to by stat_loc. Waitpid waits for the completion of a sub-process whose ID is PID (PID is-1 and information of any sub-process is returned). The stat_loc parameter serves the same purpose as the wait function, options is used to chan
The reason for testing this method is that the project needs to use this method to dynamically create required objects.
The last time we talked about how to create an object using activator. createinstance () and directly using expressions to create an object, the performance comparison was made. I was criticized by Zhao and other experts for the incorrect testing method. I decided to test it again. The testing environment is the same as that for

The differences and comparisons between SVG and canvas are as follows:SVG: Use XML to describe 2D graphics, and canvas to describe 2D graphics using JavaScript.Canvas is rendered per pixel, and in the canvas, once the drawing is done, it will not continue to get the attention of the browser. If its position changes, the entire scene also needs to be redrawn, including any objects that might have been overwritten by the graphic.SVG is based on XML, and each drawn graph is treated as an object.
