there is no build in instruction to rotate a Pixmap. you can do it through an image.
steps:
copy/convert pixmap to image
setrotation to 45
draw the image to screen:
grab rotated image from screen as pixmap

you need to use these commands:
loadimage - to convert pixmap to image
grabpixmap - to grab the pixmap from the screen
