screen

问题 I would like to convert a screen of my app and convert it into a Bitmap. I already know how to convert a view into a bitmap, but that's not what I want as my screen is made up of many fragments. Thus I'd like to be able to take the screen and convert it into a bitmap... Help is highly appreciated thanks. 回答1: You could use something like this and pass the layout as a view ;) public Bitmap takeScreenShot(View view) { // configuramos para que la view almacene la cache en una imagen view

问题 I try to change my gamma of just one screen and not all my screens. I use this code to help me But this SetDeviceGammaRamp(GetDC(IntPtr.Zero), ref s_ramp); Is for all devices. [EDIT2] I saw one weird thing : SetDeviceGammaRamp is not the same gamma of the Nvidia Panel Controller (I tried to change my value of SetDeviceGammaRamp, and it's like if i changed the value of brightness and contrast in the Nvidia panel). So i think i must to use NVidia API :/ So, how can i change this code to put my

问题 The following code captures the screen: import java.awt.Dimension; import java.awt.Rectangle; import java.awt.Robot; import java.awt.Toolkit; import java.awt.image.BufferedImage; public class capture{ public static void main(String args[]) { try { Dimension size = Toolkit.getDefaultToolkit().getScreenSize(); Robot robot = new Robot(); BufferedImage img = robot.createScreenCapture(new Rectangle(size)); } catch(Exception e) { } } } Is there a way, to capture only a desired portion of the screen

问题 What is the most efficient way to capture screen in python using modules eg PIL or cv2? Because It takes up a lot of ram. I wanted to teach AI to play dino game of Chrome through screen scraping and neat but it is way to slow... I have tried: import numpy as np from PIL import ImageGrab import cv2 import time last_time = time.time() while True: printscreen_pil = ImageGrab.grab(bbox= (0, 40, 800, 640)) printscreen_numpy = np.array(printscreen_pil.getdata(), dtype = 'uint8').reshape(

问题 I wanna create a layout compatible with a very large number of devices and screens. As I have been researching I found out that the most common screen resolutions are 249x320, 480x800, 600x1024, 720x1280 (and some other screens proportional to these). Well, after reading the documentation I found out that there are two ways of doing it. Up to the 3.2 Android version I could use qualifiers for the layouts like "small, normal, large, xlarge" and combine them with "port" (portrait orientation)

问题 When I first run my application electron with angular 4, it works normally like this but once I reload the page all becomes white When I check the DOM, everything appears normal, but the screen is still white. like this What causes the problem, how do I fix it ? 回答1: I know this is pretty old... but this is the most direct question I could find.

问题 Hi all I have problem with my QML code. I made mistake and I went to put certain size to elements and now I have problem when putting app on other devices. I will paste you my code where I have width and height so you can change it to show me how to work with dynamic resizeing. I need to say that I am calling qml file from qt with this code: QDeclarativeView *view= new QDeclarativeView; ui->setupUi(this); setCentralWidget(view); QDeclarativeContext *ctxt = view->rootContext(); ctxt-
