Background:Now in social software, the fillet of the picture can be said to be flooding, the original square QQ head, have been the secular grind flat ...So how do you turn a picture into rounded corners?You might say, "Look for the art!" "To find art!" But what if the user wants to upload a custom avatar?Or a program to deal with it!Below we use the powerful Quartz 2D to process the image ourselvesDirectly on the code:Code:I have added a classificati

WPF learning 05: 2D drawing controls Deformation Using Transform, wpftransform In WPF learning 04: 2D drawing using Shape to draw basic graphics, we learned how to draw basic graphics. This time, we further study how to deform the image.Example A triangle formed by Transform: C # code: for (int i = 0; i Shape Introduction WPF provides a Transform class that allows us to perform deformation operations on

WPF learning 05: 2D drawing Transform, wpf052dtransform In the previous article about WPF learning 04: Drawing 2D shapes, we can draw basic images. When it comes to graphic application programming, it is not enough to draw only basic graphics. We can use the Transform class provided by WPF to perform deformation operations on controls. Example A composite image rotated by a triangle: Private void Window_Loa

Frogatto (Chinese name: Tian Ji a to) a retro style 2D Horizontal Pass version of the game. Frogatto is a little frog, and the game will be centered around this little frog. Key Position: the arrow key goes up and down, the key jumps, and the S key speaks out. It is A free game, full-computer platform, and the iphone is charged. This game is quite good. The gaming model is a bit like the Super Mary on the 8-bit machine. It may seem that the screen is

Vane_background property to blue, to see if the impeller will turn blue:Node.setattr (' Vane_background ', ' Blue ');Look at the effect:Sure enough, it's OK, so we can make the impeller spin more perfect, to see exactly what to do.First, we first define a custom attribute on the node named: impeller_rotationNode.setattr (' Impeller_rotation ', 0);Then define a vector named Rotate_impeller and bind the rotation property to the impeller_rotation of the node:Ht. Default.setimage (' Rotate_impeller

This article brings you the content is about how CSS 2D conversion (example), there is a certain reference value, the need for friends can refer to, I hope to help you.

In the Android 2D Map SDK V2.2.0, there is a bug when Getcamerapositon (). Zoom gets the value is 3.0, if in the application has to use this version of 2D map, and must get this value (if not must not recommend ha), here is a not very traditional way to get, by adding a tileoverlay on the map, this overlay, do not load any new layers or data, just To get the latest level levels:The code is as follows:?

Canvas SVG DOMCanvas and SVG are both powerful 2D plotting tools. In addition, CSS and DOM can also be used to draw certain characters, and these techniques can also be used in animation to achieve animation effects. Here we will briefly compare these technologies.• Canvas: canvas draws a picture in the form of pixels without the concept of shape and vector. So there is no object to accept the event. It just draws the pixel. This is both a disadvant

Search a 2D Matrix IIWrite an efficient algorithm, searches for a value in a m x n Matrix. This matrix has the following properties: Integers in each row is sorted in ascending from left to right. Integers in each column is sorted in ascending from top to bottom. For example,Consider the following matrix:[ [1, 4, 7, one, a], [2, 5, 8,, + ], [3, 6, 9, +, +], [10, 13, 14, 17, [18, 21, 23, 26, 30]Given target = 5 , return

order of the 3D objects we render on the 2D interface:Light-to-grid (as background backplane)---> 3D modelsWell, the sequence is clear, and now the rendering begins.The light was ignored. As long as you adjust the coordinates to the model you can do without special treatment. The point is, when we render the background backplane, we call again context.clear (0, 0, 0, 1, 1, 0, context3dclearmask.depth) and render again.Cleaning depth This is mainly us

These are all entry-readable materials, all of which have a Chinese translation.The game engine can be considered a subset of the 3D game Engine + optimization (optional). The simple 2D game engine can be based on the canvas (no nodes) and the inheritance tree (without components), or even not much inheritance (direct heap Class), directly engaged. The 3D game engine is a bit more complicated.Terminology for various effects literacyIf it's just termin
