LoadFromFile Method

Applies to TestComplete 15.40, last modified on March 25, 2022

Description

The Picture.LoadFromFile method lets you load the contents of the specified image file to the given image. If the image is loaded successfully, the method returns True. Otherwise, it returns False.

Declaration

PictureObj.LoadFromFile(FileName)

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

Applies To

The method is applied to the following object:

Parameters

The method has the following parameter:

FileName

The full path to the file from which you want to load the image.

Result Value

True if the image is successfully loaded from the specified file, and False otherwise.

Remarks

Currently, TestComplete supports images having one of the following formats:

  • BMP
  • JPEG
  • PNG
  • TIFF
  • GIF
  • ICO (note that if the specified ICO file contains several images, TestComplete uploads only one of them - the one of the largest size and with the highest color depth).

TestComplete loads the image files of one of these formats regardless of the file extension. Images of an unsupported format cannot be loaded.

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);
