Hi, I try to replace font in a pdf file with c#, but it shows "The font being replaced is not a standard font of Type 1 font or a non-embeded TrueType font" .

source code:

Spire.Pdf.Graphics.Fonts.PdfUsedFont[] fonts = doc.UsedFonts;

Spire.Pdf.Graphics.PdfFont newfont = new Spire.Pdf.Graphics.PdfFont(PdfFontFamily.TimesRoman, 30f);

foreach (Spire.Pdf.Graphics.Fonts.PdfUsedFont font in fonts)
{
font.Replace(newfont); //the error occurs here!!!
}

usedfonts:
Name "Lucida Console" string
Size 9.99597 float
Style Regular Spire.Pdf.Graphics.PdfFontStyle
Type TrueTypeEmbedded Spire.Pdf.Graphics.PdfFontType
非公共成员
ActualFontName "R14" string
InternalFont {Spire.Pdf.Graphics.PdfTrueTypeFont} Spire.Pdf.Graphics.PdfFontBase {Spire.Pdf.Graphics.PdfTrueTypeFont}
ᜀ "Lucida Console" string

attached my pdf here.. I just want to update all the text in that pdf to "Century Gothic 11f". Once everything is fine, I will be buying the same for client demo.

Thanks

Hi snaren0423,

Thanks for providing your file.
Please kindly note that our Spire.Pdf currently only supports replacing standard font of type 1 and non-emmbeded true type font. I checked your document and noticed that the font is embedded. This embedded font contains ToUnicode information. If we force to replace the embedded font with another font, it is most likely to cause mess of characters. Therefore, replacing this embedded font is unreachable in our Spire.PDF. Hope you can understand.
