Langkah –langkah nya adalah sebagai berikut :
Desain lah Form seperti dibawah ini :
Dan jangan lupa untuk menambahkan komponen menustrip (pada toolbox Menu & Toolbar),OpenFileDialog (pada toolbox Dialog) dan SaveFileDialog (pada toolbox Dialog)
OpenFileDialog -> name dirubah jadi OFD
SaveFileDialog -> name dirubah jadi SFD
Kemudian ketik listing programnya seperti di bawah ini :
Public Class Form1
Dim gambar As Bitmap
Private Sub OpenCitraToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OpenCitraTolStripMenuItem.Click
OFD.Filter = "BMP|*.bmp|JPG|*.jpg"
OFD.ShowDialog()
If OFD.FileName = "" Then Exit Sub
Pic1.Image = Image.FromFile(OFD.FileName)
gambar = New Bitmap(Pic1.Image)
End Sub
Private Sub SFD_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SaveCitraToolStripMenuItem.Click OFD.Filter = "JPG|*.jpg|BMP|*.bmp"
SFD.ShowDialog()
If OFD.FileName = "" Then Exit Sub
If OFD.FilterIndex = 1 Then
gambar.Save(OFD.FileName, System.Drawing.Imaging.ImageFormat.Jpeg)
End If
If OFD.FilterIndex = 2 Then
gambar.Save(OFD.FileName, System.Drawing.Imaging.ImageFormat.Bmp)
End If
End Sub
Private Sub GrayscaleToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles GrayscaleToolStripMenuItem.Click
Dim Pb, Pc As Integer
Dim Rt, vM, vH, vB As Double
With gambar
For Pb = 0 To .Height - 1
For Pc = 0 To Width - 1
vM = .GetPixel(Pc, Pb).R
vH = .GetPixel(Pc, Pb).G
vB = .GetPixel(Pc, Pb).B
Rt = (vM + vH + vB) / 3
.SetPixel(Pc, Pb, Color.FromArgb(Rt, Rt, Rt))
Next
Pic1.Image = gambar
Pic2.Refresh()
Next
End With
End Sub
Maka Hasilnya seperti di bawah ini...
