[英]MigraDoc and PDFsharp showing different documents when saving as PDF and image
保存时,图像的设计正确,但PDF上的文本错误。 您能解释一下为什么文件不同吗?
我也欢迎其他解决方案用于保存整个文档的PDF以及打印多页文档的选定页面的功能。
谢谢 :)
编辑:图像显示的是正确的日期(“ 2016年5月24日”),我希望PDF显示,但PDF显示的是“ TEST TEST”

public static void pdf() {
DateTime now = DateTime.Now;
string filename = "MixMigraDocAndPdfSharp.pdf";
filename = Guid.NewGuid().ToString("D").ToUpper() + ".pdf";
PdfDocument document = new PdfDocument();
SamplePage1(document);
document.Save(filename);
Process.Start(filename);
}

static void SamplePage1(PdfDocument document) {
PdfPage page = document.AddPage();
XGraphics gfx = XGraphics.FromPdfPage(page);
gfx.MUH = PdfFontEncoding.Unicode;
gfx.MFEH = PdfFontEmbedding.Default;
XFont font = new XFont("Verdana", 13, XFontStyle.Bold);
gfx.DrawString("TEST TEST", font, XBrushes.Black,
new XRect(100, 100, page.Width - 200, 300), XStringFormats.Center);
Document doc = new Document();
Section sec = doc.AddSection();
Paragraph para = sec.AddParagraph();
header("24th May 2016");
DocumentRenderer docRenderer = new DocumentRenderer(doc);
docRenderer.PrepareDocument();
docRenderer.RenderObject(gfx, XUnit.FromCentimeter(5), XUnit.FromCentimeter(10), "12cm", para);
PageInfo info = docRenderer.FormattedDocument.GetPageInfo(1);
int dpi = 150;
int dx, dy;
if (info.Orientation == PdfSharp.PageOrientation.Portrait) {
dx = (int)(info.Width.Inch * dpi);
dy = (int)(info.Height.Inch * dpi);
} else {
dx = (int)(info.Height.Inch * dpi);
dy = (int)(info.Width.Inch * dpi);
}
Image image = new Bitmap(dx, dy, PixelFormat.Format32bppRgb);
Graphics graphics = Graphics.FromImage(image);
graphics.Clear(System.Drawing.Color.White);
float scale = dpi / 72f;
graphics.ScaleTransform(scale, scale);
gfx = XGraphics.FromGraphics(graphics, new XSize(info.Width.Point, info.Height.Point));
docRenderer.RenderPage(gfx, 1);
gfx.Dispose();
image.Save("test.png", ImageFormat.Png);
doc.BindToRenderer(docRenderer);
docRenderer.RenderObject(gfx, XUnit.FromCentimeter(5), XUnit.FromCentimeter(10), "12cm", para);
Process.Start("mspaint", "test.png");
}

public static void header(String date) {
Paragraph paragraph = new Paragraph();
var dateIssued = firstPage.AddTextFrame();
dateIssued.Height = "1.0cm";
dateIssued.Width = "6.0cm";
dateIssued.Left = "2.1cm";
dateIssued.RelativeHorizontal = RelativeHorizontal.Margin;
dateIssued.Top = "3.55cm";
dateIssued.RelativeVertical = RelativeVertical.Page;
paragraph = dateIssued.AddParagraph(date);
}
您调用docRenderer.RenderPage(gfx, 1);
仅用于图像。 这将呈现标题。
您不调用docRenderer.RenderPage(gfx, 1);
用于PDF。 因此,那里没有日期,只有您之前绘制的“ TEST TEST”。
