WPF equivalent to TextRenderer

Hi,

I have used TextRenderer to Measure the length of a string and therefore size a control appropiatly. Is there an equivalent in WPF or can I simply use TextRendered.MeasureString?

Cheers,

James

• Take a look at the FormattedText class

  If you need more granular control, then you'd need to descend to the GlyphTypeface type's AdvanceWidths member. Found a similar discussion here with a code snippet that looks like it might work.

  Update: Looks like this may be a duplicate of Measuring text in WPF .. OP please confirm.

• Thanks Gishu,

  Reading your links I came up with the following both of which do the job for me:

      /// <summary>
      /// Get the required height and width of the specified text. Uses FortammedText
      /// </summary>
      public static Size MeasureTextSize(string text, FontFamily fontFamily, FontStyle fontStyle, FontWeight fontWeight, FontStretch fontStretch, double fontSize)
      {
          FormattedText ft = new FormattedText(text,
                                               CultureInfo.CurrentCulture,
                                               FlowDirection.LeftToRight,
                                               new Typeface(fontFamily, fontStyle, fontWeight, fontStretch),
                                               fontSize,
                                               Brushes.Black);
          return new Size(ft.Width, ft.Height);
      }
  
      /// <summary>
      /// Get the required height and width of the specified text. Uses Glyph's
      /// </summary>
      public static Size MeasureText(string text, FontFamily fontFamily, FontStyle fontStyle, FontWeight fontWeight, FontStretch fontStretch, double fontSize)
      {
          Typeface typeface = new Typeface(fontFamily, fontStyle, fontWeight, fontStretch);
          GlyphTypeface glyphTypeface;
  
          if(!typeface.TryGetGlyphTypeface(out glyphTypeface))
          {
              return MeasureTextSize(text, fontFamily, fontStyle, fontWeight, fontStretch, fontSize);
          }
  
          double totalWidth = 0;
          double height = 0;
  
          for (int n = 0; n < text.Length; n++)
          {
              ushort glyphIndex = glyphTypeface.CharacterToGlyphMap[text[n]];
  
              double width = glyphTypeface.AdvanceWidths[glyphIndex] * fontSize;
  
              double glyphHeight = glyphTypeface.AdvanceHeights[glyphIndex]*fontSize;
  
              if(glyphHeight > height)
              {
                  height = glyphHeight;
              }
  
              totalWidth += width;
          }
  
          return new Size(totalWidth, height);
      }
