Inserting a table with more than 10K rows is very slow.
Workaround:
Use the following approach with SpreadStreamProcessing,SpreadProcessing and PdfProcessing:1) Generate an xlsx document with RadSpreadStreamProcessing
2) Import the document from 1) with RadSpreadProcessing
3) export 2) to PDF
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();formatProvider.ImportSettings.CopyStream = true;
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.
By specification, the last line of the file contains only the end-of-file marker, %%EOF. If the file contains many trailing bytes at its end, a NotSupportedException: 'StartXRef keyword cannot be found.', is thrown.
Workaround: Trim any content after the end-of-file marker (see FixInvalidEndOfFile).
I have read that there limitations to PDF files being imported, however, the file being imported was generated with FixedContentEditor, so, should be able to import?
using (Stream stream = Stream){
try
{
this._document = provider.Import(stream);
_InputPath = fileName;
}
catch (Exception e)
{
Errors = "Could not open file " + fileName + ": " + e.Message;
this._document = null;
}
}
}
When exporting a document referencing PdfProcessing`s .NET Standard assemblies with PdfComplianceLevel set an exception is thrown.
The common annotation properties are described in table "Entries common to all annotation dictionaries" of the Pdf specification.
Declined: Handling a partial annotation import-export could lead to exporting invalid PDF documents.
