Title	Stretch a picture to fill a PictureBox
Description	This example shows how to stretch a picture to fill a PictureBox in Visual Basic 6. It uses the PaintPicture method.
Keywords	stretch, picture, squeeze, resize
Categories	Graphics

When the form resizes, it makes the picVisible control fill the form. When the picVisible control resizes, the program uses the PaintPicture method to copy a hidden picture onto it.

' Make picVisible fill the form.
Private Sub Form_Resize()
    picVisible.Move 0, 0, ScaleWidth, ScaleHeight
End Sub

' Copy the image into picVisible.
Private Sub picVisible_Resize()
    picVisible.PaintPicture picHidden.Picture, _
        0, 0, picVisible.ScaleWidth, _
        picVisible.ScaleHeight, _
        0, 0, picHidden.ScaleWidth, _
        picHidden.ScaleHeight, vbSrcCopy
End Sub

My book Visual Basic Graphics Programming shows how to resize a picture smoothly without jagged aliasing effects.
