NAME

       visgrep - Visual grep, greps for images in another image

SYNOPSIS

       visgrep [options] image.png detect.pat match.pat ...

DESCRIPTION

       visgrep is a program that greps for image in another image.

       All  .pat  files are created using png2pat(1) or rgb2pat(1). The image.png is scanned for detect.pat starting from X,Y given in parameters.
       When detect.pat is found, then all the match.pat files are scanned at an offset of x,y given in parameters. If a match is found, then  vis-
       grep prints the x,y and index of the item.

       For  example,  image.png  is a screenshot and match1.pat .. match5.pat are images of letters a to e. Each of these letters is enclosed in a
       blue box, so detect.pat is an image of the upper left corner of the box. This box is not included in the  match*.pat  files,  so  they  are
       actually offset 5 pixels down and 4 pixels to the left.	You might run it like this then:

	 visgrep -x-4 -y5 image.png match_corner.pat match_a.pat match_b.bat ...

       Etc, with all matches listed. Now suppose the screen showed ace so visgrep might output:

	 10,10 0
	 50,10 2
	 90,10 4

       Showing that match_a.pat (index 0) is at 10,10 on the screen. If no match is found even though the detection image is found, the index will
       be -1.

OPTIONS

       A summary of options is included below.

       -h     Show summary of options.

       -x     Set x offset for detection matching.

       -y     Set y offset for detection matching.

       -X     Start scanning at X.

       -Y     Start scanning at Y.

       -t     Set tolerance for 'fuzzy' matches, higher numbers are more tolerant.

EXIT STATUS

       0      at least one match was made.

       1      no matches were made.

       2      an error occured.

NAME

       Regexp::Common::list -- provide regexes for lists

SYNOPSIS

	   use Regexp::Common qw /list/;

	   while (<>) {
	       /$RE{list}{-pat => 'w+'}/	   and print "List of words";
	       /$RE{list}{-pat => $RE{num}{real}}/ and print "List of numbers";
	   }

DESCRIPTION

       Please consult the manual of Regexp::Common for a general description of the works of this interface.

       Do not use this module directly, but load it via Regexp::Common.

   $RE{list}{-pat}{-sep}{-lastsep}
       Returns a pattern matching a list of (at least two) substrings.

       If "-pat=P" is specified, it defines the pattern for each substring in the list. By default, P is "qr/.*?S/". In Regexp::Common 0.02 or
       earlier, the default pattern was "qr/.*?/". But that will match a single space, causing unintended parsing of "a, b, and c" as a list of
       four elements instead of 3 (with "-word" being "(?:and)").  One consequence is that a list of the form "a,,b" will no longer be parsed. Use
       the pattern "qr /.*?/" to be able to parse this, but see the previous remark.

       If "-sep=P" is specified, it defines the pattern P to be used as a separator between each pair of substrings in the list, except the final
       two.  By default P is "qr/s*,s*/".

       If "-lastsep=P" is specified, it defines the pattern P to be used as a separator between the final two substrings in the list.  By default
       P is the same as the pattern specified by the "-sep" flag.

       For example:

	     $RE{list}{-pat=>'w+'}		   # match a list of word chars
	     $RE{list}{-pat=>$RE{num}{real}}	   # match a list of numbers
	     $RE{list}{-sep=>"	"}		   # match a tab-separated list
	     $RE{list}{-lastsep=>',s+ands+'}	   # match a proper English list

       Under "-keep":

       $1  captures the entire list

       $2  captures the last separator

   $RE{list}{conj}{-word=PATTERN}
       An alias for $RE{list}{-lastsep=>'s*,?s*PATTERNs*'}

       If "-word" is not specified, the default pattern is "qr/and|or/".

       For example:

	     $RE{list}{conj}{-word=>'et'}	 # match Jean, Paul, et Satre
	     $RE{list}{conj}{-word=>'oder'}	 # match Bonn, Koln oder Hamburg

   $RE{list}{and}
       An alias for $RE{list}{conj}{-word=>'and'}

   $RE{list}{or}
       An alias for $RE{list}{conj}{-word=>'or'}
