Removes font bytes from the PDF file.
BitMiracle.Docotic.Pdf (in BitMiracle.Docotic.Pdf.dll)
Public Function Unembed As Boolean
if font bytes were successfully removed; otherwise, false
This method might fail to remove font bytes in the following cases:
The font is not embedded. For such fonts the Embedded
property is false.
The font is used by one of form controls (PdfTextBox, PdfComboBox,
etc.) and therefore can't be unembedded. A PDF reader might be unable to view or change
text in a control if the control uses an unembedded font.
The font is a Type3 font. Type3 fonts cannot be unembedded by its nature.
PDF readers will not be able to load the font after unembedding.
It is not recommended to remove any font bytes if you plan to save the current document
as a PDF/A document. PDF/A documents should have all used fonts embedded. Therefore,
the library will try to embed all font bytes before producing a PDF/A.
Some PDF documents use a same font descriptor and font bytes in multiple fonts. In such cases,
the call of this method for first font will also remove font bytes for all other fonts.
