|Pic.Draw||Part of Pic module|
|Syntax||Pic.Draw (picID, x, y, mode : int)|
|Description||Pic.Draw is used to draw a picture on the screen. The picture
is drawn with the lower left corner at (x, y).|
The mode parameter has one of the following values:
|Details||If the Pic.Draw call fails, Error.Last will return a
non-zero value indicating the reason for the failure.
Error.LastMsg will return a string which contains the textual
version of the error.|
|Example||The program draws a graphic on the screen and then repeats it 50
times in random positions.|
var picID: int var x, y : int Draw.FillBox (50, 50, 150, 150, red) Draw.FillStar (50, 50, 150, 150, green) Draw.FillOval (100, 100, 30, 30, blue) picID := Pic.New (50, 50, 150, 150) for i : 1 .. 50 x := Rand.Int (0, maxx) % Random x y := Rand.Int (0, maxy) % Random y Pic.Draw (picID, x, y, picCopy) end for Pic.Free (picID)
This means that you can only call the function by calling Pic.Draw, not by calling Draw.
