How to rotate a graphic

[Jan Schenkel]

Of course, it was a bit lazy to just tell you to read the dictionary, but I was hungry and dinner was just ready ;-)
Now, what I usually do is draw the rectangle (or roundrect, or oval,...) and then use the Gradient panel to select the gradient type and quickly set the colors; then I use this helper command to finish those linear gradients off for me:
##
command FinishLinearGradient pGraphic, pDirection
   local tGradientA, tLocation, tRectangle
   local tFrom, tTo, tVia
   --
   put the fillGradient of pGraphic into tGradientA
   put the location of pGraphic into tLocation
   put the rectangle of pGraphic into tRectangle
   if pDirection is "Vertical" then
      put (item 1 of tLocation),(item 2 of tRectangle) into tFrom
      put (item 1 of tLocation),(item 4 of tRectangle) into tTo
      put (item 1 of tRectangle),(item 2 of tRectangle) into tVia
   else
      put (item 1 of tRectangle),(item 2 of tLocation) into tFrom
      put (item 3 of tRectangle),(item 2 of tLocation) into tTo
      put (item 1 of tRectangle),(item 4 of tRectangle) into tVia
   end if
   put tFrom into tGradientA["from"]
   put tTo into tGradientA["to"]
   put tVia into tGradientA["via"]
   set the fillGradient of pGraphic to tGradientA
end FinishLinearGradient
##
I put it into a helper plugin that's loaded at startup; and then I can just type into the message box:
##
FinishLinearGradient the selectedObject, "vertical"
##
And everything is set correctly without fiddling with the controls...
