There's and example at http://www.planetsourcecode.com, but it involves you having to paint every pixel at it's new location, which is very slow.

angle = 30 * 3.14 / 180
slope = Tan(angle)
for j = 0 to Picture1.ScaleHeight
i = (Picture1.ScaleHeight - j) * slope
BitBlt Picture2.hDC, i, j, Picture1.ScaleWidth, 1, Picture1.hDC, 0, j, vbSrcCopy
next
Picture2.Refresh
