We are pleased to announce the release of Aspose.Imaging for .NET 3.9.0. The major development in this release is support for creating EMF metafile image. This release supports PSD file created/updated using SAI and GIMP2 tools. Support to export text as shapes while converting EMF metafile to SVG format has also been incorporated in this release.

Create EMF Metafile Image

Aspose.Imaging for .Net now supports creating EMF metafile image. Aspose.Imaging for .Net provides the EmfRecorderGraphics2D class to create EMF metafile. Below provided sample code demonstrates how to create EMF metafile.

 private void Gen_EMF_Image()
{
    // EmfRecorderGraphics2D class provides you the frame or canvas to draw shapes on it.
    // Create an instance of EmfRecorderGraphics2D class. The constructor takes in 3 parameters:
    // 1. Instance of Imaging Rectangle class
    // 2. Instance of Imaging Size class
    // 3. Instance of Imaging Size class
    Aspose.Imaging.FileFormats.Emf.Graphics.EmfRecorderGraphics2D graphics = new Aspose.Imaging.FileFormats.Emf.Graphics.EmfRecorderGraphics2D(
        new Aspose.Imaging.Rectangle(0, 0, 1000, 1000),
        new Aspose.Imaging.Size(1000, 1000),
        new Aspose.Imaging.Size(100, 100));
    {
                
        // Create an instance of Imaging Pen class and mention its color.
        Aspose.Imaging.Pen pen = new Aspose.Imaging.Pen(Aspose.Imaging.Color.Bisque);
        // Draw a line by calling DrawLine method and passing x,y coordinates of 1st point and same for 2nd point along with color infor as Pen.
        graphics.DrawLine(pen, 1, 1, 50, 50);

        // Reset the Pen color.
        pen = new Aspose.Imaging.Pen(Aspose.Imaging.Color.BlueViolet, 3);
                
        // specify the end style of the line.
        pen.EndCap = LineCap.Round;

        // Draw a line by calling DrawLine method and passing x,y coordinates of 1st point and same for 2nd point along with color infor as Pen and end style of line.
        graphics.DrawLine(pen, 15, 5, 50, 60);

        // specify the end style of the line.
        pen.EndCap = LineCap.Square;

        // Draw a line by calling DrawLine method.
        graphics.DrawLine(pen, 5, 10, 50, 10);

        // specify the end style of the line.
        pen.EndCap = LineCap.Flat;

        // Draw a line by calling DrawLine method and passing parameters.
        graphics.DrawLine(pen, new Aspose.Imaging.Point(5, 20), new Aspose.Imaging.Point(50, 20));

        // Create an instance of HatchBrush class to define rectanglurar brush with with different settings.
        Aspose.Imaging.Brushes.HatchBrush hatchBrush = 
            new Aspose.Imaging.Brushes.HatchBrush() 
            { BackgroundColor = Aspose.Imaging.Color.AliceBlue, ForegroundColor = Aspose.Imaging.Color.Red, HatchStyle = HatchStyle.Cross };

        // Draw a line by calling DrawLine method and passing parameters.
        pen = new Aspose.Imaging.Pen(hatchBrush, 7);
        graphics.DrawRectangle(pen, 50, 50, 20, 30);

        // Draw a line by calling DrawLine method and passing parameters with different mode.
        graphics.BackgroundMode = Aspose.Imaging.FileFormats.Emf.Emf.Consts.EmfBackgroundMode.OPAQUE;
        graphics.DrawLine(pen, 80, 50, 80, 80);

        // Draw a polygon by calling DrawPolygon method and passing parameters with line join setting/style.
        pen = new Aspose.Imaging.Pen(new Aspose.Imaging.Brushes.SolidBrush(Aspose.Imaging.Color.Aqua), 3);
        pen.LineJoin = LineJoin.MiterClipped;
        graphics.DrawPolygon(pen, new Aspose.Imaging.Point[] 
        { 
            new Aspose.Imaging.Point(10, 20), 
            new Aspose.Imaging.Point(12, 45), 
            new Aspose.Imaging.Point(22, 48), 
            new Aspose.Imaging.Point(48, 36), 
            new Aspose.Imaging.Point(30, 55), 
        });

        // Draw a rectangle by calling DrawRectangle method.
        pen.LineJoin = LineJoin.Bevel;
        graphics.DrawRectangle(pen, 50, 10, 10, 5);

        pen.LineJoin = LineJoin.Round;
        graphics.DrawRectangle(pen, 65, 10, 10, 5);

        pen.LineJoin = LineJoin.Miter;
        graphics.DrawRectangle(pen, 80, 10, 10, 5);

        // Call EndRecording method to produce the final shape. EndRecording method will return the final shape as EmfImage.
        // So create an instance of EmfImage class and initialize it with EmfImage returned by EndRecording method.
        using (Aspose.Imaging.FileFormats.Emf.EmfImage image = graphics.EndRecording())
        {
            Test(image, "Pens.emf");
        }
    }
}

// Test method will convert the metafile image to PDF formate.
private static void Test(Aspose.Imaging.FileFormats.Emf.EmfImage image, string fileName)
{
    // Create an instance of PdfOptions class.
    PdfOptions options = new PdfOptions();

    // Create an instance of EmfRasterizationOptions class and define different settings.
    EmfRasterizationOptions rasterizationOptions = new EmfRasterizationOptions();
    rasterizationOptions.PageSize = image.Size;
    options.VectorRasterizationOptions = rasterizationOptions;

    string outPath = fileName + ".pdf";
            
    // Call the save method to convert the EMF metafile image to PDF.
    image.Save(outPath, options);
}

Export Text As Shape While Converting EMF To SVG

Using Aspose.Imaging for .Net, developers can get text as shapes while converting EMF to SVG format. Aspose.Imaging for .Net provides the TextAsShapes property to get text as shape while converting EMF metafile. Below is the code demonstration.

 string path = @"CaplifeDisclaimer_eng.emf";
string destPath = @"CaplifeDisclaimer_eng_Path.svg";
string destTextPath = @"CaplifeDisclaimer_eng_Text.svg";

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(path))
{
    EmfRasterizationOptions emfRasterizationOptions = new EmfRasterizationOptions();
    emfRasterizationOptions.BackgroundColor = Aspose.Imaging.Color.White;
    emfRasterizationOptions.PageWidth = image.Width;
    emfRasterizationOptions.PageHeight = image.Height;

    image.Save(destPath, 
        new SvgOptions() 
        { 
            VectorRasterizationOptions = emfRasterizationOptions, 
            TextAsShapes = true 
        });
    image.Save(destTextPath, 
        new SvgOptions() 
        { 
            VectorRasterizationOptions = emfRasterizationOptions, 
            TextAsShapes = false 
        });
}
