# Module annotate Methods

## AnnotateImage

AnnotateImage() annotates an image with text. Optionally you can include any of the following bits of information about the image by embedding the appropriate special characters:

          b   file size in bytes.
          c   comment.
          d   directory in which the image resides.
          e   extension of the image file.
          f   original filename of the image.
          h   height of image.
          i   filename of the image.
          k   number of unique colors.
          l   image label.
          m   image file format.
          n   number of images in a image sequence.
          o   output image filename.
          p   page number of the image.
          q   image depth (8 or 16).
          q   image depth (8 or 16).
          s   image scene number.
          t   image filename without any extension.
          u   a unique temporary filename.
          w   image width.
          x   x resolution of the image.
          y   y resolution of the image.

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:

      ssize_t FormatMagickCaption(Image *image,DrawInfo *draw_info,
        const MagickBooleanType split,TypeMetric *metrics,char **caption)

A description of each parameter follows.

##### image

The image.

##### draw_info

the draw info.

##### split

when no convenient line breaks-- insert newline.

##### metrics

Return the font metrics in this structure.

##### caption

the caption.

## GetMultilineTypeMetrics

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

          character width
          character height
          ascender
          descender
          text width
          text height
          maximum horizontal advance
          bounds: x1
          bounds: y1
          bounds: x2
          bounds: y2
          origin: x
          origin: y
          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.

## GetTypeMetrics

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

          character width
          character height
          ascender
          descender
          text width
          text height
          maximum horizontal advance
          bounds: x1
          bounds: y1
          bounds: x2
          bounds: y2
          origin: x
          origin: y
          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:

##### image

the image.

##### draw_info

the draw info.

##### metrics

Return the font metrics in this structure.
