equation to draw an elliptic --------------------- // The x and y parameters of the function are the center of the elliptic; the and B parameters are the cross and semi axes of the elliptic, // The length of the vertical and semi-axis, which cannot be 0 at the same time // The disadvantage of this method is that when the linWidth is wider and the ellipse is relatively flat // The end of the long axis inside the elliptical is sharp, insmooth, and

Draw transparent bitmap To draw a transparent bitmap, you can use a mask. The so-called mask is a black and white bitmap. It corresponds to the bitmap to be transparent. The mask describes the parts to be transparent in the bitmap, and the parts to be transparent are black, the opacity is white, and the white part is transparent. Assume that figure A is a transparent bitmap to be drawn, and Figure B is a ma

When an activity gets the focus, it is required to draw its layout (that is, the layout set by the setcontentview () method in the oncreate method ). The android Framework processes the painting process, but the activity must also provide the layout-level root node information of the view to be drawn. PS: The last sentence must be explained here. We all know that a layout file is an XML file containing multiple levels. The XML node information in it

Draw lines on canvasArticleIn, I talked about the method of drawing a straight line. The article on drawing a curve should have been published.

context.The cpaintdc is used in response to the window re-painting message (wm_paint) which is the drawing output. Cpaintdc calls beginpaint () in the constructor to obtain the device context, and CALLS endpaint () in the destructor to release the device context. In addition to releasing the device context, endpaint () is also responsible for clearing the wm_paint message from the message queue. Therefore, you must use cpaintdc when processing the window re-painting. Otherwise, the wm_paint mes

Address: http://ogldev.atspace.co.uk/www/tutorial02/tutorial02.html When writing OpenGL programs, we usually need the glew library, which encapsulates various OpenGL extensions for our convenience. We can call the glew initialization function in the main function, and then we can query whether OpenGL extensions can be used. For functions that can be used, we can dynamically load them. In this tutorial, we will first understand the usage of vertex buffer objects (VBO, vertex buffer object. In t

MFC has a powerful function and has a complete drawing function. On the Windows platform, the application's Graphics Device interface (INTERFACE,GDI) is abstracted into device CONTEXT,DC. In Microsoft's base Class library MFC, the CDC class is the base class that defines the device context object, and all the drawing functions are defined in the CDC base class. When you need to output text or graphics, you need to call the CDC class's member functions, which have the ability to output text and
