You can access the Image pixels in many ways:1. One using the Inbuilt macro2. One using the pointer to the image data3. Getting the raw data from the image. ============================================================Method 1: Using Inbuilt macro:CV_
用Delphi直接获取bmp图片的像素,并存储显示出.(此像素主要用在LED上显示).希望高手能给出代码啊!! function getImagePixels(f: string): Integer; var jpg: TJpegImage; bmp: TBitmap; begin Result := 0; if not FileExists(f) then Exit; if SameText(ExtractFileExt(f), '.bmp') then beg
'获取CAD屏幕像素的比值 Function ViewScreen() As Double Dim ScreenSize As Variant ScreenSize = ThisDrawing.GetVariable("screensize") '当前视口的屏幕宽度和高度 Dim H As Variant H = ThisDrawing.GetVariable("viewsize") '当前视图图形的实际高度 ViewScreen = Abs(H / ScreenS
获取RGB值思路:截图,获取图片的(0,0)的RGB值 int x = QCursor::pos().x(); int y = QCursor::pos().y(); // QPixmap pixmap = QPixmap::grabWindow(QApplication::desktop()->winId(), x, y, 1, 1); QList<QScreen *> list_screen = QGuiApplication::screens(); //可能电脑接了多个屏幕 QPi
要做一个抠图应用,所以随手做了个鼠标取色,代码如下: void mousePressed(){ int imgC = get(mouseX,mouseY); int R = (imgC >> 16) & 0xFF; int G = (imgC >> 8) & 0xFF; int B = imgC & 0xFF; println("Current position color: Red = "+R+", Green = "
