ImageMagick: MagickWand, C API for ImageMagick: Magick Wand Methods
Author: ImageMagick Studio LLC
Description: ImageMagick (TM) is a free software suite to create, edit and compose bitmap images. It can read, convert and write images in a large variety of formats. Images can be cropped, colors can be changed, various effects can be applied, images can be rotated and combined, and text, lines, polygons, ellipses and Bézier curves can be added to images and stretched and rotated. ImageMagick is free software: it is delivered with full source code and can be freely used, copied, modified and distributed. Its license is compatible with the GPL. It runs on all major operating systems. Most of the functionality of ImageMagick can be used interactively from the command line; more often, however, the features are used from programs written in the programming languages Perl, C, C++, Python, PHP, Ruby or Java, for which ready-made ImageMagick interfaces (PerlMagick, Magick++, PythonMagick, MagickWand for PHP, RubyMagick, and JMagick) are available. This makes it possible to modify or create images automa [cell cut: 1159 characters, first 1000 kept]

      MagickBooleanType MagickGetIteratorIndex(MagickWand *wand)
A description of each parameter follows: #### wand The magick wand. ## MagickQueryConfigureOption MagickQueryConfigureOption() returns the value associated with the specified configure option. The format of the MagickQueryConfigureOption function is:
      char *MagickQueryConfigureOption(const char *option)
A description of each parameter follows: #### option The option name. ## MagickQueryConfigureOptions MagickQueryConfigureOptions() returns any configure options that match the specified pattern (e.g. "*" for all). Options include NAME, VERSION, LIB_VERSION, etc. The format of the MagickQueryConfigureOptions function is:
      char **MagickQueryConfigureOptions(const char *pattern,
        unsigned long *number_options)
A description of each parameter follows: #### pattern Specifies a pointer to a text string containing a pattern. #### number_options Returns the number of configure options in the list. ## MagickQueryFontMetrics MagickQueryFontMetrics() returns a 7 element array representing the following font metrics:
          Element Description
          -------------------------------------------------
          0 character width
          1 character height
          2 ascender
          3 descender
          4 text width
          5 text height
          6 maximum horizontal advance
The format of the MagickQueryFontMetrics method is:
      double *MagickQueryFontMetrics(MagickWand *wand,
        const DrawingWand *drawing_wand,const char *text)
A description of each parameter follows: #### wand The Magick wand. #### drawing_wand The drawing wand. #### text The text. ## MagickQueryMultilineFontMetrics MagickQueryMultilineFontMetrics() returns a 7 element array representing the following font metrics:
          Element Description
          -------------------------------------------------
          0 character width
          1 character height
          2 ascender
          3 descender
          4 text width
          5 text height
          6 maximum horizontal advance
This method is like MagickQueryFontMetrics() but it returns the maximum text width and height for multiple lines of text. The format of the MagickQueryFontMetrics method is:
      double *MagickQueryMultilineFontMetrics(MagickWand *wand,
        const DrawingWand *drawing_wand,const char *text)
A description of each parameter follows: #### wand The Magick wand. #### drawing_wand The drawing wand. #### text The text. ## MagickQueryFonts MagickQueryFonts() returns any font that match the specified pattern (e.g. "*" for all). The format of the MagickQueryFonts function is:
      char **MagickQueryFonts(const char *pattern,unsigned long *number_fonts)

The format of the MagickQueryFonts function is:
      char **MagickQueryFonts(const char *pattern,
        unsigned long *number_formats)
A description of each parameter follows: #### pattern Specifies a pointer to a text string containing a pattern. #### number_formats This integer returns the number of image formats in the list. ## MagickRelinquishMemory MagickRelinquishMemory() relinquishes memory resources returned by such methods as MagickIdentifyImage(), MagickGetException(), etc. The format of the MagickRelinquishMemory method is:
