Installing Mono on Ubuntu Mono is not available in the standard Ubuntu 20.04 repositories. Prerequisites The instructions assume that you are logged in as root or user with sudo privileges. G.CopyFromScreen(,, 0, 0, ) īitmap.Save(imageStream, ImageFormat.Png) Ĭontents = stream => memoryStream. This tutorial covers the steps required to install Mono on Ubuntu 20.04. Using (var g = Graphics.FromImage(bitmap)) I didn't dispose of the MemoryStream since I'm not sure it will successfully return the value if you do, but you could play around with it. I haven't tested this, but here I've made your instances local, and disposed of the Graphics and Bitmap instances. The GC will collect it eventually, but you can place your code in a using block to let it know you're done with it. Part of your issue may be that you're new'ing up a Graphics instance repeatedly, but never disposing of the old reference. Graphics.CopyFromScreen(,īitmapScreenCapture.Save(memoryStream, ImageFormat.Png) Ĭontents = stream => memoryStream.CopyTo(stream)Īs much as possible, keep variables in the most local scope possible, and dispose of what you can. Graphics = Graphics.FromImage(bitmapScreenCapture) If (bitmapScreenCapture = null || bitmapScreenCapture.Width != || bitmapScreenCapture.Height != )īitmapScreenCapture = new Bitmap(, ) Private MemoryStream memoryStream = new MemoryStream() After choosing the area, tap the Camera icon to take the screenshot or press the Video icon if. ![]() A simple press on Alt + S will let you choose the area you want. By dragging it, you can place it anywhere on the screen. Is my code bad, or is nancy not suitable for handling many big responses, or maybe C# method of capturing screen is poorly optimized and I should try pinvoke methods? Or maybe it's just a terrible way to do it and I should try something more advanced, like using VNC library?Ĭurrently my code looks like this: public class HomeModule : NancyModule Upon installing the app, a system tray will appear on the right side of the screen. I thought it won't be a big problem, so I chose C# and nancy It seems to settle on taking about 3.5 GB RAM and from then no longer grows, but that's not an acceptable amount - even with big resolution (mine is 2560x1440). I want it to be able to serve one every 1-2 seconds through LAN. Be more clear with annotated screenshots. I am trying to make a small application to serve screenshot of entire screen through network.
