Contains an asynchronous extension to write PDF content to a LEAD stream. PdfCompressorExtensions is an abstract class and cannot be created directly.
public abstract PdfCompressorExtensions
PdfCompressorExtensions provides an extension method to the namespace Leadtools.PdfCompressor
.
The WriteAsync(PdfCompressorEngine,ILeadStream) method is implemented in Leadtools.Async.dll as an extension to the Leadtools.PdfCompressor namespace and
is part of the Leadtools.PdfCompressor.PdfCompressorExtensions
class.
The extension method WriteAsync(PdfCompressorEngine,ILeadStream) will not show up unless a reference to Leadtools.Async.dll is added to your project.

Reference to Leadtools.Async.dll and Leadtools.PdfCompressor.dll are required to use the extension in this class.
