Avoid Page Breaks Inside Images Using API

EVO PDF Client for .NET Core

You can avoid page breaks inside the <IMG> HTML elements if you set on true the PdfDocumentOptionsAvoidImageBreak flag of the converter. An object of PdfDocumentOptions type is exposed by the HtmlToPdfConverterPdfDocumentOptions property. Avoiding page break inside an image is possible only if the element height is smaller than the next PDF page height.
