Video with alpha channel in Processing

…衆ロ難τιáo~ 提交于 2019-12-03 01:12:24
问题 I was wondering if anyone can be amazing and help me with something I'm working on in Processing . I need to play a video file with transparencies over a live feed so that the video isn't simply a rectangle. Here is the section of the code that I think I need to add something to or change. I'm extremely new to all of this and I'm extremely grateful to anyone that can help. 回答1: If you're video has an alpha channel, that's great, otherwise, you should be able to blend() the other content.

Since symbols are CPU specific, the above only works if you have imported the symbols not only for a specific iOS device but also for a specific CPU type. The currently CPU types needed are armv7 (e.g.

Very much appreciated. If anyone can help me with this final question, that'd be great If I have lines in a text file that look like this: 1 4:48:08 Orvar Steingrimsson 1979 30 - 39 ara IS200 2 4:52:25 Gudni Pall Palsson 1987 18 - 29 ara IS870 How can I output this data onto a new text file but only listing three things: year - name - time ... so that these two lines would look like this: 1979 Orvar Steingrimsson 4:48

Stop processing Flask route if request aborted

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: I have a flask REST endpoint that does some cpu-intensive image processing and takes a few seconds to return. Often, this endpoint gets called, then aborted by the client. In these situations I would like to cancel processing. How can I do this in flask? In node.js, I would do something like: req.on('close', function(){ //some handler }); I was expecting flask to have something similar, or a synchronous method (request.isClosed()) that I could check at certain points during my processing and return if it's closed, but I can't find one. I

The main problem I have is that all the Go processes seems to execute exactly the same calculation. I reproduced here the problem with a very simple example. I obtain : 4 + 50 = 54 4 + 50 = 54 4 + 50 = 54 instead of : 1 + 20 = 21 2 + 30 = 32 3 + 40 = 43 If I move up "wg.Wait()" I obtain the good result but no parallelism :( Thank's in advance for your comments ! package main import ( "fmt" "runtime" "sync" ) func process_array ( x , y int ) int { r := x + y return r }

Processing after the request was completed

If, however, I log some stuff to the database it now takes closer to 10ms. How would you approach completing the request and then doing some kind of processing after the request was completed? I tried with Response.Body.Flush(), but that doesn't complete the request and it still takes the full 10ms. It looks like it's sending/flushing the payload, but the request still doesn't complete until the action method is completed. Would it

Queue-Based Background Processing in ASP.NET MVC Web Application

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: How can I implement background processing queues in my ASP.NET MVC web app? While most data changes, updates etc. need to be visible immediately, there are other updates that don't need real time processing which I would like to hand off to a lower-priority background process which will take care of it at its own pace. As an example, take StackOverflow's badge award system. Usually you may take a specific action that would award you a badge, but the actual 'award' happens later (typically between 10 minutes and a couple hours later). I
