When an import of the attached PDF file is executed, the result is a file with vertically rotated images, as well as enlarged and distorted. This is part of the code executed in the final application. Do you have any idea why this is happening? Is there any suggested solution?
As a result of the imported file, other processes are executed, such as creating bookmarks and page numbering, but the result is incorrect when presenting the rotated images.
Please find attached a code snippet and the input and generated output file.
Thank you.
private static void TestPDF()
{
RadFixedDocument document;
Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.PdfFormatProvider providerPdf = new();
using (Stream stream = System.IO.File.OpenRead("C:\\TMP\\Ejemplo1-Input.pdf"))
{
document = providerPdf.Import(stream);
byte[] output = providerPdf.Export(document);
System.IO.File.WriteAllBytes("C:\\TMP\\Ejemplo1-Output.pdf", output);
}
}
SkiaImageFormatProvider: Rectangle behind text overlaps the text of previous line.
RESOLVED: The issue is dismissed. The actual reason for the results is missing FontsProvider implementation. In order for accurate calculations and measurements the fonts used in the document need to be resolved correctly.
I'm currently working with the large PDFs. I'm able to process PDFs up to 2.1 GB easily without any error using Telerik Document Processing. However, if I take a larger PDF (e.g. 2.8 GB), PdfFormatProvider.Import throws an IOException with the next message: "The parameter is incorrect. : {path}".
I'm using FileStream to provide a sample for the Import method.
I've checked it with the different samples, all have the same behavior. So, I guess, it will work for any PDF larger than 2.1 GB.
Hello, I had many problems with version 2023.1.117, latest stable 2023.2.606 is unusable also due to issue with scanned documents etc, so I tried 2020.2.703-hotfix, but I am getting other set of issues.
Unfortunately I cannot share the documents, since they are confidential.
With some documents I am getting this error:
Unable to cast object of type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Types.PdfName' to type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Elements.Objects.FormXObject'.
Loading Code:
PdfFormatProvider pdfFormatProvider = new();
RadFixedDocument document = pdfFormatProvider.Import(bytes);

I'm trying to use the PdfFormatProvider to import a pdf. I've tried to import multiple different pdfs with the code below, but they all throw an exception with "System.InvalidOperationException: 'Import not supported.'" and no other info. Is this a bug or am I not calling the correct method to import a pdf?
var providerPDF = new Telerik.Windows.Documents.Flow.FormatProviders.Pdf.PdfFormatProvider(); providerPDF.Import(File.ReadAllBytes(@"D:\TestDocs\TestImage.pdf"));
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;
}
}
}
Hi,
I am trying to convert a HTML body to a PDF using HtmlFormatProvider and PdfFormatProvider.
It works well when I try to create a pdf with "normal" characters, but when I use characters like "åäö" the characters is either missing or replaced with other character.
I have found a similiar issue but that was due to the fact that the person was using .net core I am using .net framework.
Am I missing something when I am converting it to a PDF or is there a limitation with special characters like "åäö".
private string CreateAndStorePdf(string htmlBody)
{
Telerik.Windows.Documents.Extensibility.JpegImageConverterBase jpegImageConverter = new Telerik.Documents.ImageUtils.JpegImageConverter();
Telerik.Windows.Documents.Extensibility.FixedExtensibilityManager.JpegImageConverter = jpegImageConverter;
var provider = new HtmlFormatProvider();
var document = provider.Import(htmlBody);
var exportProvider = new PdfFormatProvider();
var fixedExportProvider = new Telerik.Windows.Documents.Flow.FormatProviders.Pdf.PdfFormatProvider();
var fileName = "_original.pdf";
try
{
using (var outputStream = new MemoryStream())
{
exportProvider.Export(fixedExportProvider.ExportToFixedDocument(document), outputStream);
outputStream.Seek(0, SeekOrigin.Begin);
var pdfBytes = new BinaryReader(outputStream).ReadBytes((int)outputStream.Length);
return fileName;
}
}
catch (Exception ex)
{
Log.Error(ex, "The pdf could not be created.");
return null;
}
}
Hello Support,
I am generating pdf using PdfFormatProvider. In this i am passing html data which should be converted into pdf. For that I have written below code.
HtmlFormatProvider htmlFormatProvider = new HtmlFormatProvider(); RadFlowDocument htmlDocument = htmlFormatProvider.Import(htmlContentValue); var anotherpara = sectionBody.Blocks.AddParagraph(); editor.MoveToParagraphStart(anotherpara); editor.InsertDocument(htmlDocument, options);
This works fine and also get pdf with expected value. But I would like to set spacing between two lines which I could not set or its not working. For that I have added below code.
I have also attached screenshot for it. like how its showing on pdf
editor.ParagraphFormatting.AutomaticSpacingAfter.LocalValue = false; editor.ParagraphFormatting.AutomaticSpacingBefore.LocalValue = false; editor.ParagraphFormatting.SpacingAfter.LocalValue = 0; editor.ParagraphFormatting.SpacingBefore.LocalValue = 0;
So could you please let me know fix for it.
I was working on some acroforms and wherever I needed a space I kept on getting a different letter (Ê). On debugging the problem seems to be in the TryGetCharCode function of OpenTypeFontSource
Version: 2019.3.917
Below is copy of function
public override bool TryGetCharCode(int unicode, out int charCode)
{
bool result = false;
ushort glyphId;
charCode = CMap.MISSING_GLYPH_ID;
if (this.TryGetGlyphId(unicode, out glyphId))
{
ushort uCharCode = CMap.MISSING_GLYPH_ID;
CMapTable table = this.CMap.GetCMapTable(3, 0);
if (table != null)
{
result = table.TryGetCharId(glyphId, out uCharCode);
}
table = this.CMap.GetCMapTable(1, 0);
if (table != null)
{
result = table.TryGetCharId(glyphId, out uCharCode);
}
charCode = uCharCode;
return result;
}
return false;
}
The font used has 2 cmap tables: one with platformid of 3 and encodingid of 1, the other with platformid 1 and encodingid 0. According to https://docs.microsoft.com/en-us/typography/opentype/spec/cmap platform id 3 and encoding 1 is correct for windows so not sure why the first call to getcmaptable looks for encodingid 0.
Second of all even if I change it to the following
CMapTable table = this.CMap.GetCMapTable(3, 1);
if there is a second cmap with platformid of 1 whatever the result of the call with regards to platformid 3, the result will be overridden
I can say that if I add some checks so that if the first call succeeds it doesn't attempt the 2nd I do get the expected behaviour in the pdf and get spaces
As a note the FontFamily property of the OpenTypeFontSource is "Arial"
