resolution

问题 I've been using pygame to make a game recently, and have ran into a little problem... Basically, I would like to be able to stretch the whole image that is on the screen (all the things that I have blitted to it) into the resolution which the user has resized the window to. I've searched a lot on the documentation for pygame and on stack overflow and I can't seem to find an answer... Is it even possible? The source code for my game is pretty big atm, if anyone needs it I'll be willing to post

问题 I am trying to plot two timeseries in one graph. Unfortunatelly, the data sets have different temporal resolutions and my code using datetime does not work. My aim is one xtick per hour. Any idea how I can solve that problem? Thanks! dataset1 = rand(1,230).'; dataset2 = rand(1,33).'; xstart = datenum('19/02 09:00','dd/mm HH:MM'); xend = datenum('21/02 18:00','dd/mm HH:MM'); x = linspace(xstart,xend,20); Dat = linspace(xstart,xend,numel(dataset1)); x1=[1:1:230].' %values every 15 minutes x0_OM

问题 I got a problem with resolution of setTimeout. When I set it to 50 ms, it varies from 51 to even 80 ms. When I use sleep module, I am able to get resolution like 50 µs, so what is the setTimeout function problem to get at least 1 ms? Is there any way to fix/avoid that? The problem with sleep is that it delays everything even when callback function should be shoot, it waits... Is there an alternative solution to shoot some events in delay of exactly 50 ms? For example with sleep module: var

问题 I have a Custom DirectShow Video Renderer Filter which has some extended features over Microsoft's Video Renderer Filter like overlay images. I know I could do the same with a Transform Filter but I've chosen that way. I also believe, I would face the same problem with a Transform Filter which I'll describe below. When I use Microsoft's Video Renderer Filter , it is capable of resizing the window and buffer sizes automatically when stream starts/changes. My filter is capable of doing the same

问题 I'm creating a CSS responsive site. How can I go about hiding the dropdown menu at mobile screen resolution? And having it show up again when at larger resolutions? (I'm new to jQuery) This is my html: <div id="menuContainer"> <ul id="menu"> <li id="about"> <a href="about.html">About</a> <ul class="dropdown"> <li> <a href="#">Link 1</a> </li> <li> <a href="#">Link 2</a> </li> <li> <a href="#">Link 3</a> </li> </ul> </li> </ul> </div> And my jQuery: $('#menu li ul').css({ display: "none", });

问题 I want to Retrieve Image Resolution(DPI) of an image (JPEG,PNG,SVG,GIF) without using any PHP extension (like imageMagick). I searched everywhere, but I couldn't find a perfect solution. I tried below code (got from link) function get_dpi($filename){ $a = fopen($filename,'r'); $string = fread($a,20); fclose($a); $data = bin2hex(substr($string,14,4)); $x = substr($data,0,4); $y = substr($data,0,4); return array(hexdec($x),hexdec($y)); } But I am not getting the correct Horizontal and vertical

问题 Thanks in advance for your help. I am wondering how I might go about accessing the screen resolutions available on a user's PC. I would like to get a list of all available resolutions and also determine what the user is current running at. 回答1: I believe you can make a PInvoke call to EnumDisplaySettings api call in User32.dll. [DllImport("user32.dll")] public static extern bool EnumDisplaySettings (string deviceName, int modeNum, ref DEVMODE devMode ); See example here. You'll of course run

问题 I create an application for iPhone using PhoneGAP. I create design of application for 640x1136 resolution. But when I tried to run application into iPhone 6.1 simulator the resolution was 320x548 instead of 640x1136. I check the simulation screen resolution using following JavaScript code. $("#width").text(window.innerWidth); $("#height").text(window.innerHeight); To accomplish this, I tried the following steps Edit your Info.plist file in /Developer/Platforms/iPhoneSimulator.platform

问题 In the Android res folder, we are presented with a few different folders that deal with different resolutions for images. In the past I have only used one image with the same resolution in one folder, and this has worked well for my specific applications. However, I'm hoping to make my future Android apps look essentially the same across an array of screen resolutions and devices. Any rules or guidelines to go by when creating different resolution sizes for the same image to put in each

问题 I have a dell laptop latitude 5420. The built-in monitor has a width of 12.20 inches and a height of 6.69 6,86 inches. OS is Windows7. The screen resolution is set to 1600 by 900 (prefered resolution). Additionally Windows7 is configured with a "Set custom text size (DPI)" of 100% (9 point Segoe UI at 96 pixels per inch). I think this means windows7 thinks 1 inch of my monitor uses 96 pixels. If I divide 1600 pixels by 12.20 inches (or 900 by 6,86) it results around 131,1. What should be the
