Motivation : Capture the internal state of an object without compromising encapsulation, and save the state outside the object. In this way, the object can be restored to the previously saved state. Scenario: The Graphic System is used as an example. The circle is the primary machine. The system processes the circle and stores the recoverable sequence.

method is still applicable to the blunt angle. Considering that the current mouse is in the second quadrant, the red dotted line vector and the blue solid line vector are used as reference vectors) The algorithm is implemented as follows. The idea is basically the same as above, and only some optimizations are made: Evaluate the dimensionline endpoint Algorithm Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/--> 1 Private Void

the closest distance, and obtain the least recent point. 　　Calculate the closest distance from a point to a circle and the coordinates of the intersection.: If the point is in the center of the center, undefined is returned because the distance from the center to any point in the circle is equal. The connection point P and the center O. If the Po is parallel to the X axis, the abscissa of the nearest point is calculated based on P on the left or right of O as

vertical foot, and select the endpoint closer to the vertical foot to return. Calculate the closest point of a point to a line, rectangle, or polygon: You only need to calculate the closest point to each line segment, record the closest distance, and obtain the least recent point. Calculate the closest distance from a point to a circle and the coordinates of the intersection point: If the point is in the center of the center, undefined is returned because the distance from the center

: The button outlines. Step 2: Draw the background color of the button. // Specifies the base color of the draw button. Rect. DeflateRect (3, 3, 3, 3 ); CBrush * pOldBrush = pDC-> SelectObject ( m_BackgroundBrush ); PDC-> Rectangle (rect ); PDC-> SelectObject (pOldBrush ); Here is just a simple demonstration. The buttons are not necessarily nice. Set the base color of the button to pure white. The program execution result is as follows: Step 3: Draw the text of the button. // Draw button text

closest point of a point to a line, rectangle, or polygon: You only need to calculate the closest point to each line segment, record the closest distance, and obtain the least recent point. Calculate the closest distance from a point to a circle and the coordinates of the intersection point: If the point is in the center of the center, undefined is returned because the distance from the center to any point in the circle is equal. The connection point P and the center O. If the Po is para

The most basic animation effect is transform, which can be divided into translate, rotate, scale, skew, and flip. Below is a brief summary. Translate: as long as it is a change in position (based on the change in the position of the animation object X, Y axis) Rotate: Self-rotation. In blend, the rotate under the transform label is set to angle, angle> 0, clockwise rotation; angle Scale: scale itself. For example: Scale x = 2, the X axis direction of the animation object is doubled, Ske

, the DRDs row is returned; if not, calculate the distance between the two ends and the vertical foot, and select the endpoint closer to the vertical foot to return. Calculate the closest point of a point to a line, rectangle, or polygon: You only need to calculate the closest point to each line segment, record the closest distance, and obtain the least recent point.

Draw a CircleSolve the problem of drag and drop, and then you can implement drag-and-drop drawing circle. We pass in the center point to draw the initialization circle, the default radius is 500 meters,Startdrawcircle:function (centerpoint) { this._unregistmapevents (); This.centerpoint = CenterPoint; This.circle = This._createcircle (
