PDF Tools

A new version of PDF split and merge is released.
This version fixed the crash problem in previous version. 

We add a new feature to PDFStamper ActiveX. Now it supports Fill forms in PDF file.
The syntax for filling form is easy. First add all the form field name and correspondent value (strings),

TIFF is a raster image. It has a DPI property to tell how long in inch the width or height of the image is.
When converting tiff to pdf, the default pdf DPI is 72, which means 72 pixels per inch.

When using our components like  pdf split and merge in your ASP.Net application, you need to first set the working folder access to ensure the folder can be written in ASP.Net
 1. Using Windows Explorer, navigate to the working Folder (for example C:\Inetpub\wwwroot).

We have updated the PDF Stamper component with a new method SetPageMask.
You can use this method to specify which pages you want to stamp watermark or text onto.

Recently I found an issue with our VB.Net and C# demo for PDF components. When compiling with VS2005, the component will fail to be initialized with a stack overflow error. The one compiled with VS2003 (.Net 1.1), the VB, VBScript demo all works well. So I doubt if this is a bug of .Net 2.0.
Overal it […]

We added a method to PDF security.
IsEncrypted(String file)
 This function will return 1 on an encrypted PDF, 0 on an unencrypted one. It will return negative  if there is any error.
 

PDF file format supports javascript. The script can access the pdf document object model like the HTML DOM.
When doing pdf encryption or decryption, it is necessary to keep the javascript information.

 
When developing our development tools product, we have consider the stress testing scenarios. Since our product might be used in server scenarios which means it should be stable, reliable.
