conversion between .Net image and picture object?

Hello Russell,

You can perform the conversion with Windows Clipboard. For example:

function Test()

{

  var image = dotNET.System_Drawing.Bitmap.zctor("C:\\image.bmp");

  image = dotNET.System_Windows_Interop.Imaging.CreateBitmapSourceFromHBitmap(

    image.GetHbitmap(),

    dotNET.System.IntPtr.Zero,

    dotNET.System_Windows.Int32Rect.Empty,

    dotNET.System_Windows_Media_Imaging.BitmapSizeOptions.FromEmptyOptions()

  );

  dotNET.System_Windows.Clipboard.SetImage(image);

  var picture = Sys.Clipboard;

  Log.Picture(picture);  

}

Hello Russell,

The sample was created in TestComplete 9, but it works fine in TestComplete 8, too.

In both cases, you need to configure your project's CLR Bridge settings in the following way:

• set the Preferred architecture of the assembly hosting process setting to 32-bit;


• set the Preferred apartment model of the calling thread setting to Single-threaded apartment;


• add the PresentationCore.dll, System.Drawing.dll and WindowsBase.dll assemblies from the GAC.

Hi Andrew,

Use the .NET Graphics class that provides the method. For example:

 function Test()

 { 

   var image = dotNET.System_Drawing.Image.FromFile("C:\\image.bmp"); 

   var image_graphics = dotNET.System_Drawing.Graphics.FromImage(image);

   var black_pen = dotNET.System_Drawing.Pen.zctor(dotNET.System_Drawing.Color.Black);

   image_graphics.DrawRectangle(black_pen, 0, 0, 10, 10); 

   image_graphics.DrawImage(image, dotNET.System_Drawing.Point.zctor(0, 0)); 

  

   var image_bitmap = dotNET.System_Drawing.Bitmap.zctor_10(image); 

   var bitmap_source = dotNET.System_Windows_Interop.Imaging.CreateBitmapSourceFromHBitmap(

     image_bitmap.GetHbitmap(),

     dotNET.System.IntPtr.Zero,

     dotNET.System_Windows.Int32Rect.Empty,

     dotNET.System_Windows_Media_Imaging.BitmapSizeOptions.FromEmptyOptions()

   );

  

   dotNET.System_Windows.Clipboard.SetImage(bitmap_source); 

   var picture = Sys.Clipboard;

   Log.Picture(picture); 

 }

 

Hi Andrew,

The conversion was discussed on Stack Overflow. Here is the working solution:

 function Test()

 { 

   var bitmap_source = dotNET.System_Windows.Clipboard.GetImage();

   var mstream = dotNET.System_IO.MemoryStream.zctor();

   var encoder = dotNET.System_Windows_Media_Imaging.BmpBitmapEncoder.zctor();

   encoder.Frames.Add(

     dotNET.System_Windows_Media_Imaging.BitmapFrame.Create_5(bitmap_source)

     );

   encoder.Save(mstream);

  

   var image_bitmap = dotNET.System_Drawing.Bitmap.zctor_4(mstream);

   var image_graphics = dotNET.System_Drawing.Graphics.FromImage(image_bitmap);

 }
