Get width of drawText in GraphicsMagick

I have a variable width word that I would like to center in a fixed sized box. How can I calculate the width of the text so that I know how far the left offset should be?

You did not specify your programming language so I am assuming you are using C.

You can determine the width with the MagickQueryFontMetrics methods (http://www.graphicsmagick.org/wand/magick_wand.html#magickqueryfontmetrics) this returns a double array containing the following information:

  • 0 character width
  • 1 character height
  • 2 ascender
  • 3 descender
  • 4 text width
  • 5 text height
  • 6 maximum horizontal advance

Or if you could use use the GetTypeMetrics method that gives you the information in a nice struct:

  • GetTypeMetrics(Image *image,const DrawInfo *draw_info, TypeMetric *metrics)
