Loading a Picture from a File

Your application should provide the ability to load a picture from a file if your application needs to modify the picture or if you want to store the picture outside the application so a person or another application can modify the picture. 

To load a graphics file into an image control, call the LoadFromFile method of the image control's Picture object. 

The following code gets a file name from an open picture file dialog box, and then loads that file into an image control named Image:

procedure TForm1.Open1Click(Sender: TObject);
begin
if OpenPictureDialog1.Execute then
begin
CurrentFile := OpenPictureDialog1.FileName;
Image.Picture.LoadFromFile(CurrentFile);
end;
end;

 

void __fastcall TForm1::Open1Click(TObject *Sender)
{
  if (OpenPictureDialog1->Execute())
  {
    CurrentFile = OpenPictureDialog1->FileName;
    Image->Picture->LoadFromFile(CurrentFile);
  }
}
