You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: printfigure.m
    path of file: ./repos/glider_toolbox/m/common_tools
    
    the code of the file until where you have to start completion: function imginfo = printfigure(varargin)
%PRINTFIGURE  Print figure to image file with metadata.

%  Syntax:
%    IMGINFO = PRINTFIGURE(OPTIONS)
%    IMGINFO = PRINTFIGURE(OPT1, VAL1, ...)
%    IMGINFO = PRINTFIGURE(H, OPTIONS)
%    IMGINFO = PRINTFIGURE(H, OPT1, VAL1, ...)
%
%  Description:
%    IMGINFO = PRINTFIGURE(OPTIONS) and IMGINFO = PRINTFIGURE(OPT1, VAL1, ...)
%    print current figure to image file according to given options and return a
%    struct IMGINFO with information about the generated image file.
%    Options may be given in key-value pairs OPT1, VAL1... or in a struct 
%    OPTIONS with field names as option keys and field values as option values.
%    Recognized options are:
%      DIRNAME: image file directory.
%        String with the path of the directory of the output image file.
%        It may be absolute or relative to the current directory as reported
%        by PWD.
%        Default value: '' (empty, use current directory)
%      FILENAME: image file name without extension.
%        String with name of the output image file without path prefix nor
%        extension.
%        Default value: sprintf('figure%03d', h) where h is the figure handle
%      FORMAT: image file format (extension)
%        String with the extension of the output image file (no leading dot).
%        It also specifies the image format. Any format recognized by the
%        program 'convert' in the ImageMagick suite may be used. See note on 
%        format below.
%        Default value: 'eps'
%      RESOLUTION: image resolution in dots per inch.
%        Positive integer with the resolution of the output image file in dpi.
%        See note on image size below.
%        Default value: 72
%      DATE: image time stamp.
%        String with the value of the 'date' property of the output image file,
%        usually the creation date. Some image formats might not support it.
%        Default value: datestr(now(), 31)
%      TITLE: image title label.
%        String with the value of the 'title' property of the output image file.
%        Some image formats might not support it.
%        Default value: ''
%      COMMENT: image description comment.
%        String with the value of the 'comment' property of the output image
%        file. Some image formats might not support it. It should describe the
%        figure contents.
%        Default value: ''
%      DRIVER: driver to print intermediate vector image file.
%        String setting whether the intermediate vector image file should be 
%        printed using a mono or color driver. It should be one of:
%          'eps'  : mono
%          'eps2' : mono
%          'epsc' : color
