Hopefully very easy: how to I get from there, to saving the data to file as an image? Temporary file string strFile = StringConcatenate( ChartID(), GetTickCount(), ".I've got a image saved to the clipboard by emulating PRINTSCREEN using the below code. ![]() #define GMEM_MOVEABLE 2 #define CF_DIB 8 #define SZBITMAPHEADER 14 bool CopyScreenshotToClipboard() The application must not free the handle nor leave it locked. The application should copy the data immediately. Private Declare PtrSafe Function GetClipboardData Lib 'user32' (ByVal wFormat As Integer) As Long. The clipboard controls the handle that the GetClipboardData function returns, not the application. Int SetClipboardData( int Format, int hMem) An application can enumerate the available formats in advance by using the EnumClipboardFormats function. ![]() #import "user32.dll" int OpenClipboard( int hOwnerWindow) #import "kernel32.dll" int GlobalAlloc( int Flags, uint Size) For a detailed tutorial on how to read and display an image, please check here. To do so, we will call the imread function from the imported cv2 module, passing as input the path to the image. Same principle as copying text to the clipboard, but slightly more complicated as a result of needing to create a temporary screenshot file and then read it back from disk. Then, we will read an image from our file system.
