PDFsharp image to XImage

Question

I created a barcode as an image in my ASP.NET MVC app.

BarcodeLib.Barcode barcode = new BarcodeLib.Barcode()                   
{                        
    IncludeLabel = false,
    Alignment = AlignmentPositions.LEFT,
    Width = element.BarcodeWidth,
    Height = element.BarcodeHeight,
    RotateFlipType = RotateFlipType.RotateNoneFlipNone,
    BackColor = Color.Transparent,
    ForeColor = Color.Black,
    ImageFormat = System.Drawing.Imaging.ImageFormat.Png
 };

This will create a barcode with the BarcodeLib.
How do I convert it to an XImage of PDFsharp?

Image img = barcode.Encode(TYPE.CODE128, "123456789");
gfx.DrawImage(xImage, 0, 0, 100, 100);

Answer 1

Solved it this way:

Image img = barcode.Encode(TYPE.CODE128, Name); // this is the image

MemoryStream strm = new MemoryStream();
img.Save(strm, System.Drawing.Imaging.ImageFormat.Png);

XImage xfoto = XImage.FromStream(strm);

Actually method had been changed in .net core version. It takes Func as parameter. Attention please: It's unofficial version for .net core.

XImage xImage = XImage.FromStream(() => new MemoryStream(yourByte[]));

Are you sure? Please look at the method, after then we can discuss about that – Sedgemoor

Looks like an inofficial port of PDFsharp (I don't know which). Most likely it didn't exist in 2017 when the question was asked. Not useful to illustrate special extensions of special ports without clearly identifying the port they belong to. – Funch

That's right, It's an unofficial but this is so useful for .net core otherwise you have to change most of things. So please correct your scoring. – Sedgemoor

If you use the GDI build of PDFsharp then you can call the XImage.FromImage method.

With any build of PDFsharp you can write an PNG image to a MemoryStream and then get an XImage from that MemoryStream.

There is also XImage.FromStream, so you can add images created in a MemoryStream. You'll need version 1.5 for that. – Peroxidize

Also, If you know image path you can use that

XImage xImage = XImage.FromFile(imagePath)
