I have a pdf file with a custom font. The font size when I look in Acrobat is 7.56. The font size returned by PdfTextObject (or Pdfium.FPDFTextObj_GetFontSize) is 1. Is there a way to get the size of a font when the text was created with a custom font?

Attached is a sample PDF with the issue.

Thanks,

In fact, in the provided document, the font size is indeed set to 1.
And the size of the text that you see when rendering, appears as a result of applying the transformation matrix.. Examine the textObject.Matrix property. You will find there a scaling factor equal to exactly 7.56.

Thanks Paul. Can you point me something to learn more about the textObject.Matrix properties. (Not sure what a,b,c...f mean).

I'm trying to get the height of a character given a particular font and font size. My approach is to create a new PdfTextObject using an existing font and text object. For example,

PdfTextObject.Create("A", 1, 1, textObject.Font, textObject.FontSize);

The problem is the font size of the existing object. Should I be using the "D" property of the matrix to get the font size?

Thanks,

Ted

You may use original font size and matrix.
Or just call PdfTextObject.Clone();
