m有一个网格:companysnapshot ..网格导出到磁盘然后再从磁盘中取出并导出到pdf。 下面的代码工作正常,导出与图像完成。 bt问题是......
- >图片从UI保存为黑色背景..当导出的内容在白色背景中更改时(可能会将其转换为png)
- >我想在pdf页面中对齐图像的坐标
有没有办法增加图像或pdf页面的宽度。 这是一个新手...如果有人为此编写了一些代码,那将会很有帮助。
private void PrepareDocument(RadDocument document)
{
document.SectionDefaultPageOrientation = PageOrientation.Landscape;
document.LayoutMode = DocumentLayoutMode.Paged;
document.Measure(RadDocument.MAX_DOCUMENT_SIZE);
document.Arrange(new RectangleF(PointF.Empty, document.DesiredSize));
}

private void CreateChartDocumentPart(RadDocument document, Grid whGrid, Grid companysnapshot, Grid chartgridimage)
{
Telerik.Windows.Documents.Model.Section section = new Telerik.Windows.Documents.Model.Section();
Telerik.Windows.Documents.Model.Paragraph paragraph = new Telerik.Windows.Documents.Model.Paragraph();
Telerik.Windows.Documents.Model.Span span1;
using (MemoryStream ms = new MemoryStream())
{
companysnapshot.Measure(new System.Windows.Size(double.PositiveInfinity, double.PositiveInfinity));
int companywidth = (int)Math.Round(companysnapshot.ActualWidth);
int companyheight = (int)Math.Round(companysnapshot.ActualHeight);
companywidth = companywidth == 0 ? 1 : companywidth;
companyheight = companyheight == 0 ? 1 : companyheight;
RenderTargetBitmap rtbmp = new RenderTargetBitmap(companywidth, companyheight, 96d, 96d, PixelFormats.Default);
rtbmp.Render(companysnapshot);
BmpBitmapEncoder encoder = new BmpBitmapEncoder();
encoder.Frames.Add(BitmapFrame.Create(rtbmp));
FileStream fs1 = File.Create(@"C:\Users\Admin\Desktop\Chart12xx.bmp");
encoder.Save(fs1);
fs1.Close();
// this.ExportPNGToImage(chart, ms);
paragraph.LeftIndent = 0;
paragraph.RightIndent = 0.0;
FileStream ss = File.Open(@"C:\Users\Admin\Desktop\Chart12xx.bmp", FileMode.Open);
ImageInline image = new ImageInline(ss, new Size(companywidth, companyheight), "bmp");
paragraph.FlowDirection = FlowDirection.LeftToRight;
paragraph.Inlines.Add(image);
ss.Close();
//Span spacespan = new Span(" ");
//paragraph.Inlines.Add(spacespan);
}
try
{
section1.Blocks.Add(paragraph);
document.Sections.Add(section1);
}
catch (Exception)
{
}
// paragraph.Inlines.Add(new Span(FormattingSymbolLayoutBox.LINE_BREAK));
}
