What's New in this Release?

We are pleased to announce the release of Aspose.Pdf for .NET 10.1.0. When using the API in trial mode, you get the limitations to manipulate/add certain number of elements inside PDF file. The limitation includes adding/removing number of pages from PDF file, adding/manipulating Attachments or Annotations inside PDF file, conversion of only first 4 pages to Image format and so on. Also when using the API in trial mode (without using the license), a watermark text is added in resultant file and you also come across an error message stating that API is being used in evaluation mode. So before performing any operation, we can also check the license initialization and for this purpose, a static read-only property named IsLicensed is added in Document class. We generate the PDF files on the fly and during PDF file creation, we may come across the requirement (creating Table Of Contents etc) to get page count of PDF file without saving the file over system or stream. So in order to cater this requirement, a method ProcessParagraphs(…) has been introduced in Document class. Please take a look over following code snippet which shoes the steps to get page count without saving the document. A text can be added inside paragraphs collection of PDF file using TextFragment instance or by using TextParagraph object and even you can stamp the text inside PDF by using TextStamp class. While adding the text, we may have a requirement to specify character spacing for text object. In order to accomplish this requirement, a new property named CharacterSpacing property has been introduced. Please take a look over following approaches to fulfill this requirement. Adding text stamps inside PDF file is one of the salient features of our API and while adding Text Stamp, we may have a requirement to rotate the text stamp. In order to accomplish this requirement, a property named RotateAngle is present inside TextStamp class. You can pass any angle value which can be applied to rotate Stamp instance. Please take a look over following code snippet which illustrates the steps to rotate TextStamp at 45 degree angle when placing it inside PDF file. Recently one of the customers reported an issue where paragraph break was being added at the end of each line instead adding it at the end of paragraph. In order to cater this requirement, a new property named AddReturnToLineEnd is added in DocSaveOptions class. As well as the enhancements and features discussed above, there have been specific improvement for PDF to HTML and HTML to PDF conversion features. Among these fixes, the PCL to PDF, SVG to PDF, PDF to Excel, PDF to TIFF and TIFF to PDF conversion, conversion of PDF to PDF/A compliant documents, text replacement, rendering PDF files to XPS format are also improved.
