I have an png image 120x120. I want to take a part of it (10x10) and zoom it by a factor of x32 and show it to a picturebox
pixelated.
what i have done:
bmp = New Bitmap(320, 320, PixelFormat.Format32bppArgb) 'create a bitmap x32
Dim g As Graphics = Graphics.FromImage(bmp)
'draw the part in that bitmap
g.DrawImage(My.Resources.MyImage, New Rectangle(0, 0, 320, 320), New Rectangle(50, 50, 10, 10), GraphicsUnit.Pixel)
PictureBox1.Image = bmp
g.Dispose()
The image is not pixelated. What can I do to fix it?

You have to specify in your graphics:
g.InterpolationMode = InterpolationMode.NearestNeighbor
and change the rectangles to:
g.DrawImage(My.Resources.MyImage, New RectangleF(0, 0, 320, 320), New RectangleF(49.5, 49.5, 10, 10), GraphicsUnit.Pixel)
so you will not lose half a pixel.
