How can I get pixel data from a window with Golang
To get pixel data from a window in Go, you can use the github.com/go-vgo/robotgo
package. Here's an example:
gopackage main
import (
"fmt"
"github.com/go-vgo/robotgo"
)
func main() {
// Get the screen size
screenWidth, screenHeight := robotgo.GetScreenSize()
// Set the window coordinates and dimensions
windowX := 100
windowY := 100
windowWidth := 500
windowHeight := 500
// Capture the screen image within the window area
screenImage := robotgo.CaptureScreen(windowX, windowY, windowWidth, windowHeight)
// Get the pixel color at a specific point within the window
pixelColor := robotgo.GetPixelColor(windowX+10, windowY+10)
// Print the pixel color information
fmt.Println("Pixel Color:", pixelColor)
// Save the captured screen image to a file
robotgo.SaveCapture(screenImage, "screenshot.png")
}
In the above example, we use the CaptureScreen
function to capture the screen image within the specified window coordinates and dimensions. Then, we use the GetPixelColor
function to get the color of a specific pixel within the window. Finally, we save the captured screen image to a file using the SaveCapture
function.
Make sure to install the go-vgo/robotgo
package by running go get github.com/go-vgo/robotgo
before running the code.
Note that the robotgo
package uses platform-specific libraries, so you may need to install additional dependencies depending on your operating system. Refer to the go-vgo/robotgo
documentation for more information.
