Description

The Picture.SaveToFile method saves the image represented by the Picture object to a file. The image format is specified by the method parameters.

Declaration

PictureObj.SaveToFile(FileName, Configuration)

PictureObj	An expression, variable or parameter that specifies a reference to a Picture object
FileName	[in]	Required	String
Configuration	[in]	Optional	An `ImageConfiguration` object
Result	Boolean

Applies To

The method is applied to the following object:

Picture

Parameters

The method has the following parameters:

FileName

The name of the file to which you want to save the image.

If you omit the Configuration parameter, the file extension specifies the format of the saved image:

Format	Extension
BMP	.bmp or .dib
JPEG	.jpg, .jpeg, .jpe or .jfif
PNG	.png
TIFF	.tif or .tiff
GIF	.gif
ICO	.ico

If the FileName parameter specifies a file that does not exist, the method will create the file. If the parameter specifies a file that already exists, the method will replace the file.

If the parameter specifies a file residing in a non-existent location, the method will fail to save the file. To avoid possible problems, you can first create the needed location by using the aqFileSyste.CreateFolder method.

Configuration

An ImageConfiguration object that specifies the format, color and compression settings for the image to be saved. To create a new ImageConfiguration object, use the Picture.CreatePictureConfiguration method.

If this parameter is omitted, the image format is specified by the file extension (see description of the FileName parameter).

Result Value

True, if the image is successfully saved to the specified file, and False otherwise.

Example

The following example demonstrates how to create an empty Picture object using the Utils.Picture method and how to work with images using methods of the Picture object.

JavaScript

function Test1()
{
  var Pict, NewPict, x, y;

  // Creates a new empty Picture object
  Pict = Utils.Picture;

  // Loads the image from a file and posts it to the log
  Pict.LoadFromFile("D:\\Data\\my_image.png");
  Log.Picture(Pict);

  // Obtains the bounds of the new image
  x = Pict.Size.Width - 10;
  y = Pict.Size.Height - 10;

  // Obtains the new Picture object containing the specified rectangular area of the loaded image
  NewPict = Pict.GetRect(0, 0, x, y);

  // Changes the color of the top left pixel of the new image to the red color
  NewPict.$set("Pixels", 0, 0, clRed);

  // Saves the obtained picture to the new file and posts the image to the log
  NewPict.SaveToFile("D:\\Data\\my_new_image.png");
  Log.Picture(NewPict);
}

JScript

function Test1()
{
  var Pict, NewPict, x, y;

  // Creates a new empty Picture object
  Pict = Utils.Picture;

  // Loads the image from a file and posts it to the log
  Pict.LoadFromFile("D:\\Data\\my_image.png");
  Log.Picture(Pict);

  // Obtains the bounds of the new image
  x = Pict.Size.Width - 10;
  y = Pict.Size.Height - 10;

  // Obtains the new Picture object containing the specified rectangular area of the loaded image
  NewPict = Pict.GetRect(0, 0, x, y);

  // Changes the color of the top left pixel of the new image to the red color
  NewPict.Pixels(0,0)= clRed;

  // Saves the obtained picture to the new file and posts the image to the log
  NewPict.SaveToFile("D:\\Data\\my_new_image.png");
  Log.Picture(NewPict);
}

Python

def Test1():
  
  # Creates a new empty Picture object
  Pict = Utils.Picture;

  # Loads the image from a file and posts it to the log
  Pict.LoadFromFile("D:\\Data\\my_image.png")
  Log.Picture(Pict)

  # Obtains the bounds of the new image
  x = Pict.Size.Width - 10
  y = Pict.Size.Height - 10

  # Obtains the new Picture object containing the specified rectangular area of the loaded image
  NewPict = Pict.GetRect(0, 0, x, y)

  # Changes the color of the top left pixel of the new image to the red color
  NewPict.Pixels[0,0] = clRed

  # Saves the obtained picture to the new file and posts the image to the log
  NewPict.SaveToFile("D:\\Data\\my_new_image.png")
  Log.Picture(NewPict)

VBScript

Sub Test1
  Dim Pict, NewPict, x, y

  ' Creates a new empty Picture object
  Set Pict = Utils.Picture

  ' Loads the image from a file and posts it to the log
  Call Pict.LoadFromFile("D:\Data\my_image.png")
  Log.Picture(Pict)

  ' Obtains the bounds of the new image
  x = Pict.Size.Width - 10
  y = Pict.Size.Height - 10

  ' Obtains the new Picture object containing the specified rectangular area of the loaded image
  Set NewPict = Pict.GetRect(0, 0, x, y)

  ' Changes the color of the top left pixel of the new image to the red color
  NewPict.Pixels(0,0)= clRed

  ' Saves the obtained picture to the new file and posts the image to the log
  Call NewPict.SaveToFile("D:\Data\my_new_image.png")
  Log.Picture(NewPict)
End Sub

DelphiScript

procedure Test1;
var Pict, NewPict, x, y;
begin
  // Creates a new empty Picture object
  Pict := Utils.Picture;

  // Loads the image from a file and posts it to the log
  Pict.LoadFromFile('D:\Data\my_image.png');
  Log.Picture(Pict);

  // Obtains the bounds of the new image
  x := Pict.Size.Width - 10;
  y := Pict.Size.Height - 10;

  // Obtains the new Picture object containing the specified rectangular area of the loaded image
  NewPict := Pict.GetRect(0, 0, x, y);

  // Changes the color of the top left pixel of the new image to the red color
  NewPict.Pixels(0,0) := clRed;

  // Saves the obtained picture to the new file and posts the image to the log
  NewPict.SaveToFile('D:\Data\my_new_image.png');
  Log.Picture(NewPict);
end;

C++Script, C#Script

function Test1()
{
  var Pict, NewPict, x, y;

  // Creates a new empty Picture object
  Pict = Utils["Picture"];

  // Loads the image from a file and posts it to the log
  Pict["LoadFromFile"]("D:\\Data\\my_image.png");
  Log["Picture"](Pict);

  // Obtains the bounds of the new image
  x = Pict["Size"]["Width"] - 10;
  y = Pict["Size"]["Height"] - 10;

  // Obtains the new Picture object containing the specified rectangular area of the loaded image
  NewPict = Pict["GetRect"](0, 0, x, y);

  // Changes the color of the top left pixel of the new image to the red color
  NewPict["Pixels"](0,0)= clRed;

  // Saves the obtained picture to the new file and posts the image to the log
  NewPict["SaveToFile"]("D:\\Data\\my_new_image.png");
  Log["Picture"](NewPict);
