properties of rectangle

It's also computational ry, And I feel addicted to computational ry recently. Of course, it will also be used at work, but it generally calls the boost geometry library directly at work. The last time I wrote the smallest surrounded circle, this time is the smallest surrounded rectangle, which is more complex than the smallest surrounded circle. The smallest enclosed rectangle may be not necessarily an upri

From: http://golen.blog.sohu.com/96114249.html Creating a good standard web site requires more consideration for scalability. A website with good scalability will bring great convenience for later maintenance and upgrade.Now, let's summarize how to create a scalable rounded rectangle since I made the Web: Method 1: Name: round.gif: The Code is as follows: Here is a rounded rectangle with a width of 416px,

[Function description] This method is used to draw a rounded rectangle on the canvas by specifying the rectf object and the radius of the rounded corner. This method is the main method to draw a rounded rectangle. You can also set the hollow effect of the paint brush to draw a hollow rounded rectangle.

Problem descriptionn adjacent rectangles are placed on the horizontal axis, the width of each rectangle is 1, and the height of the first (1≤i≤n) rectangle is hi. These n rectangles form a histogram. For example, the height of the six rectangles is 3, 1, 6, 5, 2, 3, respectively. Find the rectangle with the largest area in the given histogram, and its edges

In the process of doing an Android project, we always encounter the need to use rounded rectangle controls to display icons, pictures, or buttons, one solution is to create a shape layout XML file under Drawable, and a custom control class that inherits from ImageView.
