The format of the AnnotateImage method is:

      MagickBooleanType AnnotateImage(Image *image,DrawInfo *draw_info)

A description of each parameter follows:

##### image

The image.

##### draw_info

The draw info.

## FormatMagickCaption

FormatMagickCaption() formats a caption so that it fits within the image width. It returns the number of lines in the formatted caption.

The format of the FormatMagickCaption method is:

      long FormatMagickCaption(Image *image,DrawInfo *draw_info,char *caption,
        TypeMetric *metrics)

A description of each parameter follows.

##### image

The image.

##### draw_info

The draw info.

##### metrics

Return the font metrics in this structure.

## GetMultilineTypeMetrics

GetMultilineTypeMetrics() returns the following information for the specified font and text:

          character height
          ascent
          descent
          text width
          text height
          maximum horizontal advance
          underline position
          underline thickness

This method is like GetTypeMetrics() but it returns the maximum text width and height for multiple lines of text.

The format of the GetMultilineTypeMetrics method is:

      MagickBooleanType GetMultilineTypeMetrics(Image *image,
        const DrawInfo *draw_info,TypeMetric *metrics)

A description of each parameter follows:

##### image

The image.

##### draw_info

The draw info.

##### metrics

Return the font metrics in this structure.

          text height
          maximum horizontal advance
          underline position
          underline thickness

The format of the GetTypeMetrics method is:

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

A description of each parameter follows:
