How to move a server license to a new server”

The following article describes how you can move a server license.

Do I need a license for my developers

No, you can continue to use the unlicensed software for the development environment. The only difference with the licensed software is that unlicensed software contains a watermark on the output.

What is the difference between an upgrade license and a regular license

An upgrade license can only be activated if you already own the last version of the product. Thus if you already own a PDFKit.NET 3.0 Server License, you can purchase the PDFKit.NET 4.0 Server License (Upgrade). If you own a 2.0 license you need to purchase a new license.

I am now using PDFKit.NET 3.0 and want to upgrade to 4.0. Is 4.0 fully backwards compatible?

Yes PDFKit.NET 4.0 is fully backwards compatible. Please note that this is not the case for upgrading from PDFKit.NET 2.0 or 1.0.

Is it possible to create high resolution PDF's, such as 300 or even 600 dpi?

All text and curves in a PDF are vector-based so resolution does not apply to these types of graphics. Resolution does apply to embedded images though. The effective resolution of an embedded image follows directly from its physical width and height (these are set by the client application) and the resolution of the image itself (this is a given). For example, say you have a 300 x 400 bitmap and you add this to a PDF using the ImageShape. If you then set the width and height of this image to 75 x 100 points, then the effective resolution of the image is ( 300 / 75 ) * 72 = 288 DPI.

I open the type reference (.chm) but each page seems to be missing?

By default XP SP2 does not trust a .chm that originates from the internet. Right-click the help file, select 'Properties' and click the 'Unblock' button on the 'General' tab.

Can PDFKit.NET be used on a shared web server where I am not allowed to do any machine level configuration?

Yes, PDFKit.NET 3.0 is verifiable (or 100% managed). This means that to use PDFKit.NET in your ASP.NET application, you only have to copy the assembly to the bin folder of your virtual folder.

Is PDFKit.NET 4.0 Vista, Windows 7 and Windows Server 2008 compliant?
