What's New   

Apr 05, 2013 - AspPDF.NET 2.5 Released

The new version includes the following features and fixes:

• The PdfDocument object now implements the IDisposable interface. The implementation of the Dispose() method simply calls Close(). The object can now be used inside a using statement, as follows:

  using( PdfDocument objDoc = objPdf.OpenDocument( path ) )
  {
     ...
  }
  

• A bug in the PdfCanvas.DrawText method responsible for the error HTML rendering error: cannot obtain font "". when used with certain fonts in the HTML mode, has been fixed.
• The method PdfDocument.SaveHttp which previously internally called Response.Close() causing a hanging problem with the Google Chrome browser no long calls it thus fixing the problem.
• Various other major and minor bugs have been fixed.

Mar 04, 2013 - Service Release 2.4.0.18304 Available

This service release includes the following fixes:

• A bug responsible for the appearance of the "replacement character" <?> (0xFFFD) in text strings extacted via the PdfPage.ExtractText method has been fixed.
• The PdfDocument.OpenImage method has been improved to allow TIFF images employing JPEG compression, as well as TIFF images with a non-standard Planar Configuration tag, to be recognized.

Feb 04, 2013 - AspPDF.NET 2.4 Released with Major Form Enhancements

The new version contains a series of major improvements in AspPDF.NET's form fill-in functionality. The following new features have been added:

• SetFieldValue, the workhorse method of the form fill-in module, has been enhanced to support fields with font size set to "auto". The handling of Unicode characters in form fields has also been improved.
• In response to your numerous requests, a "fontless" version of the SetFieldValue method, called SetFieldValueEx, has been added to the PdfAnnot object. The new method only takes a single argument, the text string. It determines the font automatically based on the information embedded in the PDF form being filled in. For more information, see Section 12.1.2 of the user manual.
• Form flattening functionality has been added via the new PdfForm method Flatten. Flattening a form means turning all of its fields into static graphics with no possibility for further editing. For more information, see Section 12.5 of the user manual.
• Various minor bugs have been fixed.

Jan 21, 2013 - AspPDF.NET 2.3 Released

The new version offers the following features:

• Support for a variety of color spaces has been added, namely DeviceGray, CalRGB, CalGray, Lab, ICCBased, Indexed, Separation and DeviceN. Previous versions only supported the DeviceRGB and DeviceCMYK color spaces.

  Two new objects, PdfColorSpace and PdfFunction, have been added to the AspPDF.NET object model to represent color spaces and their supplementary tools, transformation functions. A whole new chapter, Chapter 16, has been added to the User Manual to describe these two objects in detail.

• The SetFieldValue method of the PdfAnnot object has been improved to fix the "shifting text" problem (the content of form field shifts slightly when the field is switched from the display to edit mode.)

Dec 06, 2012 - AspPDF.NET 2.2 Released

The new version offers the following features:

• The form fill-in functionality has been extended to include image fields via the method PdfAnnot.SetFieldImage described in Section 12.4 - Image Field Handling.
• Support for a new barcode, Intelligent Mail Code used by the US Postal Service, has been added:

  

  The new barcode is described in Section 13.1 - Regular Barcodes, Barcode Type #32.

• The ImportFromUrl method has been enhanced to recognize local anchors such as <A HREF="#destination"> and <A NAME="destination"> creating links between different parts of the same document. Previous versions ignored local anchors altogether.
• An internal call to Response.End in the SaveHttp method has been removed to get rid of the exception "Thread was being aborted" thrown by this method.

Oct 22, 2012 - Service Release 2.1.0.15816 Available

The service release makes AspPDF.NET visible to COM. From now on, this native .NET component can be used in a classic ASP environment. For more information on how to use AspPDF.NET (and also AspEmail.NET) from ASP, see our KB support article PS121023186.

The new method PdfDocument.CreateGraphicsFromPage creates an instance of the PdfGraphics object from another document's page which can then be drawn on this document at an arbitrary location or locations, with scaling and rotation applied if necessary.

Jul 18, 2011 - AspPDF.NET 2.0 Released with AES Support

AspPDF.NET now supports the Advanced Encryption Standard (AES) cipher with 128-bit keys in addition to the RC4 cipher. AES is also known as Rijndael.

Previous versions of AspPDF.NET could not open or operate on AES-encrypted PDF documents. An attempt to work on such a document usually resulted in the error

Decoder failed.

To encrypt a new document with AES, the Encrypt method needs to be called with -128 (negative 128) as the key length argument:

objDoc.Encrypt( "abc", "xyz", -128, pdfPermissions.pdfFull );
