VB中每16毫秒保存1个图像 [英] Saving 1 Image Every 16 Millisecond in VB

问题描述

我想每16毫秒保存1个屏幕截图。所以每1秒就有60个截图。我尝试过使用计时器，但它没有用。 （Timer1 Interval = 16）

I want to save 1 Screenshot Every 16 Millisecond. So it is 60 screenshots every 1 Second. I tried using Timers but It didn't work. (Timer1 Interval = 16)

Public Class Form1
dim cf as integer = 0
 Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click

            Timer1.Start()

End Sub

Private Sub Timer1_Tick（sender as Object，e正如EventArgs）处理Timer1.Tick

Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick

cf = cf + 1

cf = cf + 1

        Dim bmp As Bitmap
        Dim area As Rectangle = My.Computer.Screen.Bounds

        bmp =新位图（area.Width，area.Height，System.Drawing.Imaging.PixelFormat.Format32bppArgb）
        Dim g As Graphics = Graphics.FromImage（bmp）
        g.CopyFromScreen（area.X，area.Y，0,0，area.Size，CopyPixelOperation.SourceCopy）

        bmp.Save（" D：/ FRAMES /"& cf&" .png"）
   结束子

        Dim bmp As Bitmap
        Dim area As Rectangle = My.Computer.Screen.Bounds

        bmp = New Bitmap(area.Width, area.Height, System.Drawing.Imaging.PixelFormat.Format32bppArgb)
        Dim g As Graphics = Graphics.FromImage(bmp)
        g.CopyFromScreen(area.X, area.Y, 0, 0, area.Size, CopyPixelOperation.SourceCopy)

        bmp.Save("D:/FRAMES/" & cf & ".png")
    End Sub

结束等级

End Class

推荐答案

我想保存1个屏幕截图每16毫秒。所以每1秒就有60个截图。

I want to save 1 Screenshot Every 16 Millisecond. So it is 60 screenshots every 1 Second.

每秒60帧是一部电影，不是截图。 这里有一个例子

60 frames per second is a movie, not a screenshot.  There is an example here

您可以使用其中一个在线转换器转换为VB。    MS有一个可能有用的组件：

60fps将会推动它，可能需要商业SDK。

60fps is going to be pushing it, and might require a commercial SDK.
