rendering

问题 I have a contour plot and I am using the current rendering: set(gcf, 'renderer', 'zbuffer'); but it is giving me this thick red line in the plot and I don't know how to get rid of it. I tried switching to: set(gcf, 'renderer', 'opengl'); but the quality is poor and I really need to have high quality images. Any suggestions? 回答1: In general, I let MATLAB choose which renderer is most appropriate, which means leaving the RendererMode property of the figure set to its default value of auto . A

问题 This blog post (slightly annoying page there) (and that's not my blog by the way) describes a bizarre bug I ran into yesterday in Internet Explorer 8 only. The bug involves .EOT web fonts and <iframe> elements. I haven't extensively researched the exact trigger for the bug, but it's basically the case that a page using a web font that loads content into an <iframe> such that the frame also uses a web font becomes "defaced" by the browser. The previously-OK text rendered with the web font

问题 How much faster is it to use a base64/line to display images than opposed to simply linking to the hard file on the server? url(data:image/png;base64,.......) I haven't been able to find any type of performance metrics on this. I have a few concerns: You no longer gain the benefit of caching Isn't a base64 A LOT larger in size than what a PNG/JPEG file size? Let's define "faster" as in: the time it takes for a user to see a full rendered HTML web page 回答1: 'Faster' is a hard thing to answer

问题 Suppose you're in your users controller and you want to get a json response for a show request, it'd be nice if you could create a file in your views/users/ dir, named show.json and after your users#show action is completed, it renders the file. Currently you need to do something along the lines of: def show @user = User.find( params[:id] ) respond_to do |format| format.html format.json{ render :json => @user.to_json } end end But it would be nice if you could just create a show.json file

问题 I installed ALL Extra and SDK API 21-22 including changed compileSdkVersion 22 to 21 buildToolsVersion '22.0.1' to 21.1.2 but error. And Rendering Problems for API 22 and I changed to <= 21 it still. 回答1: These are the correct version that you can add in your build.gradle according to the API needs. API 24: implementation 'com.android.support:appcompat-v7:24.2.1' implementation 'com.android.support:recyclerview-v7:24.2.1' API 25: implementation 'com.android.support:appcompat-v7:25.4.0'

问题 Hope someone can help. I have a simple scenario where clicking checkboxes is driving a progress bar in WPF. The checkboxes are contained in a UserControl and the Progress bar is in a simple WPF client window. On the user control I am using two dependency properties: 1) the existing Tag property has the value I wish to bind to the progress bar value and 2) a DP called CbCount which represents the total number of checkboxes. The problem: When the application runs the progress bar's progress

问题 I have problem with form panel and binding modelView in ExtJS 5. When form panel after render, values set slowly. Example in fiddle 回答1: This is because the browser is doing a complete layout reflow when changing a Label field (which your WizardOrderRowDisplayField is extending). The Label is not really meant to display changing values. Therefore, the implementation is a bit simplistic. When changing the value it injects new DOM content into the page. When changing DOM content, the browser

问题 See: https://developers.google.com/speed/docs/insights/BlockingJS Google is talking there about "Render-Blocking JavaScript", but in my opinion that term is incorrect, confusing and misleading. It almost looks like "Google" is also not understanding it? This point is that Javascript execution is always pausing / blocking rendering AND also always pausing / blocking the "HTML parser" (at least in Chrome and Firefox). It's even blocking it in case of an external js file, in combination with an

问题 I have a datagridview which I am populating from a datasource using dgv.DataSource = table. I then use a cell formatting event to change the color of specific cells in the datagridview depending on a value. The problem that I am facing is that when looking at the data on certain pc's some random cells will appear white with no data in. The code I am using to set the color is below however it is not just the cells which I have set custom colors which appear white: private void dgvRaw

问题 Short Intro Currently I have a UITableView which is filled with custom cells that displays uploading progress for files currently being uploaded to a server. The uploading processes are simply NSURLConnection objects running asynchronously in the background using the standard asynchronous method of the NSURLConnection. The problem is that during scrolling, the UITableView, or I suppose the UIScrollView of the UITableview, kind of blocks the entire main thread, which does that vital
