问题 As per title, I'm translating and rotating an object with CSS3's transform and it works flawlessly in every browser except IE9. It works in IE9 but only if it's written directly into the .css file . It fails if set by jQuery (v. 1.5.1) with: $('#example').css('-ms-transform', 'translate(200%) rotate(45deg) translate(-200%)'); Any suggestion? 回答1: I don't know what is causing the problem. However, have you tried with cssText: $('#example').css('cssText','-ms-transform: translate(200%) rotate

问题 I'm developing my first Windows desktop application and I'm trying to figure out what the best approach would be to create the program's GUI. I know, I know... I feel stupid for asking considering the amount of data on the subject on SO. However most answers seem outdated and I'm not sure if they fit my specific project. Also tutorials for Windows 8 'metro apps' are clogging my Google search results, which is NOT what I'm looking for. I use Visual Studio. I've followed tutorials. I have basic

问题 I'm making a 3D game, where the player's back should always be facing the camera and he should move in that direction. I didn't come to the "back facing the camera" part yet, but I believe that it will be simple once I figure out how to move the player in the right direction... Though it is a 3D coordinate system, height can be ignored (z-axis) because no matter how high the camera is, the player should always be going in the same speed (the camera system is planned to function much like in

问题 Using Opengl 2.0 on android I am trying to create a class to help me draw square sprites from a texture atlas. I'm getting some weird graphical glitches(sometimes lines/ squares missing form textures), especially when the device is brought from sleep. Here is how it should look: Here is an example of the problem after waking the phone from sleep: and my code for the Renderer. package com.krazy.androidopengl; import java.nio.ByteBuffer; import java.nio.ByteOrder; import java.nio.FloatBuffer;

问题 I want to replace string[,] 2D array public static readonly string[,] first = { {"2", " ", " ", " ", "1"}, {"2", " ", "4", "3", " "}, {" ", "2", " ", "1", " "}, {" ", "1", " ", "3", " "}, {"1", " ", " ", " ", " "} }; into int[,] array int X=-1; public static readonly int[,] second = { {2, X, X, X, 1}, {2, X, 4, 3, X}, {X, 2, X, 1, X}, {X, 1, X, 3, X}, {1, X, X, X, X} }; Is it possible to convert a string[,] array to an int[,] array? If yes, how can I convert the string[,] into int[,] ? Thank

问题 This question already has answers here : How to make a Gaussian filter in Matlab (2 answers) Closed 4 years ago . How do I obtain 2D circularly symmetric Gaussian weighting function sampled out to 3 standard deviations (3 x 3) and re scaled to unit volume? 回答1: Try fspecial (Image Processing Toolbox) with the 'gaussian' option. For example, z = fspecial('gaussian', [30 30], 4); generates values on a 30 × 30 grid with sampling step 1 and standard deviation 4 . surf(z) produces the graph The
