ABCpdf is fully backward compatible. Although extensive changes
have been made to the core engine, we check that these changes
produce results that are compatible with previous versions.
There are some minor differences in behavior between the
ABCpdf11 and ABCpdf12 namespaces.
The new Chrome86 HTML conversion engine is our new default as it
is more secure than the previous one. If your HTML conversions rely
on specific output styles created by the previous default engines -
eg MSHTML - you will want to use the following line of code after
creating any Doc object, after calling Doc.Read and after calling
doc.HtmlOptions.Engine = EngineType.MSHtml;
doc.HtmlOptions.Engine = EngineType.MSHtml
For this release we have increased the default HTML timeout to
twenty seconds. If this is value you were relying on you may wish
to change the value in your code.
In ABCpdf you can set the Doc.PageNumber to set the current page
of the document. The Doc.PageNumber is one based so to find the
first page you set the property to one. In older releases setting
the property to zero was allowed, however this allowed subtle bugs
in client code to pass without error. In ABCpdf 12 if you set the
Doc.PageNumber to zero then an exception will be raised. The
solution here is to fix your code.
