Question

我在ASP.NET MVC应用程序中创建了条形码作为图像。

org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [com.example.djbcdataaccess.JDBCTest] for bean with name 'JDBCTest' defined in class path resource [applicationContext.xml]; nested exception is java.lang.ClassNotFoundException: com.example.djbcdataaccess.JDBCTest

这将使用BarcodeLib创建条形码如何将其转换为PDFsharp的XImage？

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
 };

Answer 1

如果您使用PDFsharp的GDI版本，则可以调用XImage.FromImage方法。

使用任何版本的PDFsharp，您可以将PNG图像写入MemoryStream，然后从该MemoryStream中获取XImage。

Answer 2

实际上，.net核心版本中的方法已更改。它以Func作为参数。请注意：这是.net core的非官方版本。

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

Answer 3

解决这个问题：

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);

Answer 4

另外，如果您知道图片路径，可以使用

XImage xImage = XImage.FromFile(imagePath)

PDFsharp图像到XImage
