FontHeight Property

Summary

Font height in PDF units.

Syntax

C++/CLI

Java

Python

public double FontHeight { get; set; }

public double getFontHeight(); 
public void setFontHeight( 
   double doubleValue 
);

public: 
property double FontHeight { 
   double get(); 
   void set (    double ); 
}

FontHeight # get and set (PDFTextAnnotation)

Property Value

A System.Double that represents the font height in PDF units (1/72 of an inch and bottom left). The default value is 0.

Remarks

This value contains the height of this PDF text annotation in PDF units (1/72 of an inch and bottom left). You can use the PDFDocumentPage.ConvertPoint method to convert the value to a pixels or inches and then to points if required. Here is an example:

// Get the font height in PDF units, which 1/72 of an inch, i.e. in points 
double fontHeightPoints = pdfObject.TextProperties.FontHeight; 
// Convert to inches:  
double fontHeightInches1 = fontHeightPoints / 72.0; 
// Or use PDFDocumentPage.ConvertPoint to convert to inches: 
PDFPoint pt = new PDFPoint(0, fontHeightPoints); 
double fontHeightInches2 = pdfDocumentPage.ConvertPoint(PDFCoordinateType.Pdf, PDFCoordinateType.Inch, pt).Y; 
// And pixels: 
double fontHeightPixels = pdfDocumentPage.ConvertPoint(PDFCoordinateType.Pdf, PDFCoordinateType.Pixel, pt).Y;
