| Pic.Save | Part of Pic module |
| Syntax | Pic.Save (picID : int, fileName : string) | ||||
| Description | Pic.Save is used to save a picture on the screen to a file. The fileNameparameter must give the format of the file:
| ||||
| Details | Various versions of Turing can save different formats of files.
Turing 4.1 for Windows can save only BMP format files, as they are
loss-less and can handle 24-bit depth images.
| ||||
| Details | If Pic.Save is passed an invalid picture ID, a fatal error
occurs. If the Pic.Save call fails for other (non-fatal)
reasons, 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 saves it as
a BMP file.
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, 50, 50, blue)
picID := Pic.New (50, 50, 150, 150)
Pic.Save (picID, "BMP:mypic.dat")
Pic.Free (picID)
| ||||
| Example | The following two programs save and load a file in BMP format.
% Program to save a picture in mypic.bmp
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, 50, 50, blue)
picID := Pic.New (50, 50, 150, 150)
Pic.Save (picID, "mypic.bmp")
Pic.Free (picID)
% Program to load the picture back again and draw 50 copies
var picID: int
var x, y : int
picID := Pic.FileNew ("mypic.bmp")
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)

| Status | Exported qualified. This means that you can only call the function by calling Pic.Save, not by calling Save.
