I am using the trial version of telerik for xamarin for .net core which was released last year, to convert pdf to text. Our service is hosted in Azure. The text which I get back, in certain cases the spaces are missing (say for example instead of 'I [am] here', it displays 'I[am]here'. This happens randomly.
The code which we have used is as follows -
byte[] pdfBinary = Convert.FromBase64String(inputString);A possible workaround could be to draw a rectangle around the desired Block.
RadFixedDocument document = new RadFixedDocument();
RadFixedPage page = document.Pages.AddPage();
page.Size = new Size(600, 800);
FixedContentEditor editor = new FixedContentEditor(page);
editor.Position.Translate(defaultLeftIndent, 50);
Block block = new Block();
block.InsertText("PDF");
editor.DrawBlock(block);
Block border = new Block();
border.GraphicProperties.StrokeColor = RgbColors.Black;
border.GraphicProperties.IsFilled = false;
border.GraphicProperties.IsStroked = true;
border.GraphicProperties.StrokeThickness = 1;
border.InsertRectangle(new System.Windows.Rect(block.Measure()));
editor.DrawBlock(border);
Telerik Pdf Processing Cannot open the attached pdf file and exception occur.
How do i slove it?
Code :
RadFixedDocument document = new PdfFormatProvider().Import(input);
Exception Message :
System.UriFormatException 無效的 URI: 無法剖析主機名稱。
Source :
Telerik.Windows.Documents.Fixed
Stack Trace :
於 System.Uri.CreateThis(String uri, Boolean dontEscape, UriKind uriKind)Inserting a table with more than 10K rows is very slow.
Workaround:
Use the following approach with SpreadStreamProcessing,SpreadProcessing and PdfProcessing:PdfProcessing: Signature field validation fails if a document is imported from a byte array of CopyStream property is false.
Workaround: Set the CopyStream property of the ImportSettings to true:
PdfFormatProvider formatProvider = new PdfFormatProvider();Wrong encoding is used when the PDF file contains font with custom encoding
Workaround:
foreach (var widget in field.Widgets)
{
widget.TextProperties.Font = FontsRepository.Helvetica;
}
When using the Telerik.Documents.ImageUtils.JpegImageConverter default implementation in Blazor WebAssembly application the Magick.NET library doesn't load all of its assemblies.
Workaround:
Create a custom implementation of the JpegImageConverterBase class: Create Custom JpegImageConverter in .Net Standard.
Tables should ignore fixed proffered width with the value of 0, this is the default behavior in Word as well.
Workaround (when converting Flow to PDF documents):
foreach (var item in tables)
{
if (item.PreferredWidth.Type == Telerik.Windows.Documents.Flow.Model.Styles.TableWidthUnitType.Fixed &&
item.PreferredWidth.Value == 0)
{
item.PreferredWidth = new Telerik.Windows.Documents.Flow.Model.Styles.TableWidthUnit(Telerik.Windows.Documents.Flow.Model.Styles.TableWidthUnitType.Percent, 100);
}
}
