Hi Team, 

I am trying to convert html page using url to pdf but this exception occures-

An unhandled exception of type 'System.ArgumentException' occurred in Aspose.Pdf.dll

Additional information: At most 4 text fragments can be added in evaluation mode.


Code:

hi,

I would like to check if it is possible to set the aspose.pdf to replace the text with existing pdf font?

currently we have multiple pdf templates and each template use different fonts. 
Each pdf has specific words (e.g. _Name_) which is to be replaced with database value.

at the moment, when change the _Name_ to client user, the text font/size looks different from the original font/size.

Thanks

Hi Team,

I am trying to add RadioButtonOptionField to a tabel cell, But it is throwing the NullPointerException. I don't want to mention Rectangle parameter because i need to add it to a table cell  than fixing the position using rectangle.

Version: aspose.pdf-16.10.0.jar

Error:
   at com.aspose.pdf.Annotation.m1(Unknown Source)
   at com.aspose.pdf.WidgetAnnotation.m1(Unknown Source)
    at com.aspose.pdf.Field.m1(Unknown Source)
    at com.aspose.pdf.Annotation.m1(Unknown Source)
    at com.aspose.pdf.RadioButtonField.add(Unknown Source)

Code:
Table table = new Table();
table.setMargin(new MarginInfo(20, 20,10, 0));
table.setColumnWidths("50 50");
pdfPageItem.getParagraphs().add(table);

RadioButtonField radio = new RadioButtonField(pdfPageItem);
RadioButtonOptionField opt1 = new RadioButtonOptionField(); -- > Null exception here
opt1.setOptionName("Test1");
opt1.setName("Test1");
opt1.setCaption(new TextFragment("Test1"));

Row row = table.getRows().add();
Cell cellYesField = row.getCells().add();
cellYesField.getParagraphs().add(opt1);

pdfDoc.getForm().add(radio);
pdfDoc.save("Sample.pdf");

Please let me know how i can add the options to a table cell rather than using fixed coordinates using rectangle.

Thanks,

Embed glyphs into PDF

Hallo

Is it possible to embed only used glymphs into the PDF?
I searched through the documentation, but only found something like RemoveDuplicatedFonts and RemoveSimilarFontsWithDifferentWidths. That is not what I want.
I want to know whether it is possible to tell aspose to embed only the glyphs that are actually used, instead of the whole font.

The problem I have is that the PDF gets very large when using certain fonts. If I use "NotoSansCJKjp-Regular" font from Google Noto Fonts, the document increases in size with more than 10MB.

The code snippet below demonstrates this issue. There is one table and 2 cells with some text. The result is saved in the attachment: "ResultNoto.pdf".
If I comment out the line of code that specifies usage of "NotoSansCJKjp-Regular", the resulting PDF more than 10MB smaller: "Result.pdf".
The files are attached and the sample code is below:

        List<String> fontPaths = com.aspose.pdf.Document.getLocalFontPaths();
        fontPaths.add("C:\\temp\\Noto-hinted");
        com.aspose.pdf.Document.setLocalFontPaths(fontPaths);
        
        List<String> inputStringList = new ArrayList<>();
        inputStringList.add("äöüß é ç Здравствуйте 3 df a dad  a END");
        inputStringList.add("äöüß é ç Здравствуйте  昨夜のコンサートは最高でし adsf dfg END");
        
        com.aspose.pdf.Document doc = new com.aspose.pdf.Document("Blank.pdf");
        com.aspose.pdf.Table table = new com.aspose.pdf.Table();
        table.getDefaultCellTextState().setFont(com.aspose.pdf.FontRepository.findFont("NotoSansCJKjp-Regular"));
        table.setColumnWidths("400");
        
        for (String currentString : inputStringList) {
            Row row = table.getRows().add();
            row.getCells().add(currentString);
        }

I am using aspose.pdf verson 11.8.0
        
Thank you,
Samuel

Is relative css possible with Aspose when converting pdf to html?

Hi,

I have a situation where pdfs needs to be translated to different languages. The process is to first convert it into html and the pass the html as input to translator API. Translator returns the translated html with original html tags intact. Now if the translated text isn't of the same size of text in original language then overlapping happens and the readability is affected. So want to know if relative stylingpossible with Aspose. Attaching picture of position styling generated by Aspose.

When using find and replace in an existing pdf document, we found that Aspose pdf is not re-flowing the content and, as such, some content is overlaying or leaving large blank areas.  In the documentation it is stated that this issue does not occur, but as of which version?  We are using 6.9.0.0 in an established application.

Table Page Break (PDF)

Hello!

I am trying to stop Aspose PDF from page breaking in the middle of a table in C# .NET. I have not found any answers that have solved this problem through Google, Stackoverflow, or this forum.

We have a table with two rows that must always be together as they are utilized as a header. These rows are currently being split sometimes when they happen to fall on a page break. I wish to stop this from happening.

I have found the table.isBroken attribute always returns true and row.isRowBroken always returns false (from Aspose). This does not help me to stop the page from breaking in the middle of this table.

Here is a link to the post on stackoverflow: http://stackoverflow.com/questions/42079506/do-not-page-break-on-table-in-aspose-pdf-c-sharp-asp-net

Thank you for your time!

Hi Team,

I am having an issue while using the latest version (17.2.0.0) of Aspose.Pdf dll in my application.
I have a SharePoint 2013 application in which I have created a custom webpart. I have the following code in a button click event.
I have added the reference of Aspose.Pdf.dll from GAC (.Net framework 4.5).

    Aspose.Pdf.License license = new Aspose.Pdf.License();
                    license.SetLicense(ConfigurationManager.AppSettings[strPDFLicensePath]);
                    Aspose.Pdf.Generator.Pdf _pdf2 = new Aspose.Pdf.Generator.Pdf();

                    _pdf2.PageSetup.Margin.Right = 98;// r = 50; no pagewidth; 
                    _pdf2.PageSetup.Margin.Left = 75;//70,68
                    
    string strHTML = "<html><body><p>PDF text is here!</p></body></html>";
                    _pdf2.BindHTML(strHTML);
                    _pdf2.Save("D:\\TestPDF.pdf");
             
I am getting the exception at the line _pdf2.BindHTML(strHTML). 
Exception: Could not load file or assembly 'Aspose.HtmlOld, Version=17.2.0.0, Culture=neutral, PublicKeyToken=716fcc553a201e56' or one of its dependencies. The system cannot find the file specified.

Note that the same code work fine in .Net Console application. But, with WebApplication, I am facing this issue. 
Can you please suggest on what could be missing?

PDF to HTML problem when viewing html in Edge browser.

I am using version 17.4 of Aspose.Pdf.
We are converting documents from PDF to HTML for display in a web application.

For some documents, it appears there is a problem when viewing in Edge.
The image is obscured by the text unless you resize the browser window just so.

Firefox, Chrome, IE 10 and IE 11 do not show such an issue.
We are saving to a single stream with embedded resources using code similar to the documentation samples.

Is this known behavior in the Edge browser and do you have a way to work around the issue?

I have attached an example of the PDF and the generated HTML in a zip file.

I need to merge 2 different PDFs to 1. I tried append method from com.aspose.pdf.kit.PdfFileEditor but it doesn't work. Following is my code:

File target = PDFUtil.createTempFile();
FileOutputStream os = new FileOutputStream(target);
FileInputStream inpuStream1= new FileInputStream(f1);
FileInputStream inpuStream2= new FileInputStream(f2);
com.aspose.pdf.kit.PdfFileEditor editor = new com.aspose.pdf.kit.PdfFileEditor();
editor.append(inputStream1, portStream2, 1, 1, os);
os.flush();

I am pretty sure both f1 and f2 are valid pdf because I tried to concatenated them by "pdfDocument.getPages().add(addPageDocument.getPages())" it can successfully glued 2 PDFs in seprate pages but I need merge them into 1 pdf.
