You can convert the document to PDF and use the approach bellow: Currently, silent async printing may be achieved by using RadPdfViewer WPF control. Sample demo showing how to achieve this may be seen at the following forum post: http://www.telerik.com/forums/pdfviewer-print-makes-ui-unresponsive#js0YdzFWc0Oa8C3g6a18lg The RadPdfViewer WPF control used does not need to be displayed, making this demo a good workaround for ASP.NET AJAX clients.
When characters are in the ranges 61472-61566, 61565-61695, 65535-65535 they are correctly exported with Wingdings font. However, when the character value is outside these ranges the font fallback mechanism exports them with different font and this causes wrong glyph rendering in the resulted PDF.
The following code snippet shows how the Wingdings characters can be modified so that they are correctly exported to PDF when converting from WordsProcessing's RadFlowDocument:
RadFlowDocument document = new DocxFormatProvider().Import(File.ReadAllBytes(@"test_document.docx"));
foreach (Run run in document.EnumerateChildrenOfType<Run>())
{
if (run.FontFamily.GetActualValue(document.Theme).Source.Contains("Wingdings"))
{
StringBuilder modifiedText = new StringBuilder();
foreach (char character in run.Text)
{
modifiedText.Append(character > 256 ? character : (char)(character + 61440));
}
run.Text = modifiedText.ToString();
}
}
Workaround: When creating a RadFixedDocument:
using (RadFixedDocumentEditor editor = new RadFixedDocumentEditor(this.fixedDocument))
{
byte[] data = File.ReadAllBytes(@"CustomFont.ttf");
FontsRepository.RegisterFont(new FontFamily("CustomFont"), FontStyles.Normal, FontWeights.Normal, data);
FontBase customFont;
FontsRepository.TryCreateFont(new FontFamily("CustomFont"), FontStyles.Normal, FontWeights.Normal, out customFont);
editor.CharacterProperties.Font = customFont;
string text = "w";
StringBuilder modifiedText = new StringBuilder();
foreach (char character in text)
{
modifiedText.Append(character > 256 ? character : (char)(character + 61440));
}
text = modifiedText.ToString();
editor.InsertRun(text);
}
Introduce API for setting Image opacity.
The attached Workaround demonstrates how to change the opacity of the image before inserting it into the document.
Currently, PdfStreamWriter writes only PDF pages. If we implement API for merging multiple pages or whole documents we would be able to preserve links between pages (which are currently being corrupted). Merging whole documents would also allow preserving document properties (bookmarks, interactive forms, ...). For a more detailed list of the unsupported document properties you can refer to our documentation: https://docs.telerik.com/devtools/document-processing/libraries/radpdfprocessing/formats-and-conversion/pdf/pdfstreamwriter/features. We may also implement API for adding initial document properties from some existing PDF file.
byte[] data = File.ReadAllBytes("verdana.ttf");
FontFamily verdanaRegularFontFamily = new FontFamily("Verdana");
FontsRepository.RegisterFont(verdanaRegularFontFamily, FontStyles.Normal, FontWeights.Normal, data);
FontsRepository.TryCreateFont(verdanaRegularFontFamily, out FontBase verdanaRegularFont);
foreach (RadFixedPage page in mergedDocument.Pages)
{
foreach (TextFragment textFragment in page.Content.Where(c => c is TextFragment).Cast<TextFragment>())
{
textFragment.Font = verdanaRegularFont;
}
}
According to the PDF specification: "It is recommended that there be an end-of-line marker after the data and before endstream;"
