resizing bitmaps to fit the picture box

Is it possible to resize the bitmaps to fit the fixed size of the picture box without having to manually resize every bmp.
Thanks

You can use an Image box to stretch a picture to fit any size you want, but you will need to know what the aspect ratio is of the original picture. It helps to load the picture into a hidden picturebox, then record the aspect ratio, set the image box to the same ratio with the stretch property set to true, then finally copy the image from the hidden PictureBox to the ImageBox, and it will show up as big or small as you want.

Code:

---

Private Sub Form_Load()
  Dim PictureAspectRatio As Double
  Picture1.Visible = False
  Picture1.AutoSize = True
  Picture1.Picture = LoadPicture("C:\WINDOWS\Desktop\TestImage.jpg")
  PictureAspectRatio = Picture1.Width / Picture1.Height
 
  Image1.Stretch = True
  Image1.Width = Image1.Height * PictureAspectRatio
  Image1.Picture = Picture1.Picture
End Sub

---

If you really need the picture to end up in a PictureBox control, then you can use the PaintPicture method to scale the image.

Thank you

If you do not want to use an additional Image, you could use the PaintPicture method.

Code:

---

Picture2.PaintPicture picSource, 0, 0, Picture2.Width, Picture2.Height

---

Set the picture box's AutoSize property to True:

Private Sub Form_Load()
Picture1.AutoSize = True
End Sub

or do it with an Image instead (works better):

Private Sub Form_Load()
Image1.Stretch = True
End Sub

The AutoSize proeprty changes the size of the picturebox to match the bitmpa size, not the other way around.
