- Can you reproduce the bug at Examples:
- Provide example code:
package main
import (
"github.com/go-vgo/robotgo"
)
func main() {
robotgo.CaptureImg()
}❯ time go run main.go
go run main.go 0.96s user 0.95s system 12% cpu 15.653 total
Description
Just a CaptureImg call took 15s in my device. I'm not sure if it performs similarly on other OS.
I think the syscall with bitmap spend too much time.
Python's pillow library uses the subprocess method instead of syscall. It has great performance. I think we can refer to their implementation.
