NAME

       Pandoc::Filter::ImagesFromCode - transform code blocks into images

DESCRIPTION

       This Pandoc::Filter transforms CodeBlock elements into Image elements. Content of
       transformed code section and resulting image files are written to files.

       Attribute "title" is mapped to the image title and attribute "caption" to an image
       caption, if available.

CONFIGURATION

       from
           File extension of input files extracted from code blocks. Defaults to "code".

       to  File extension of created image files. Can be a fixed string or a code reference that
           gets the document output format (for instance latex or "html") as argument to produce
           different image formats depending on output format.

       name
           Code reference that maps the CodeBlock element to a filename (without directory and
           extension). By default the element's "id" is used if it contains characters no other
           than "a-zA-Z0-9_-". Otherwise the name is the MD5 hash of the element's content.

       dir Directory where to place input and output files, relative to the current directory.
           This directory (default ".") is prepended to all image references in the target
           document.

       run Command to transform input files to output files. Variable references "$...$" can be
           used to refer to current values of "from", "to", "name", "dir", "infile" and
           "outfile". Example:

             run => ['ditaa', '-o', '$infile$', '$outfile$'],

       capture
           Capture output of command and write it to "outfile". Disabled by default.

       force
           Apply transformation also if input and output file already exists unchanged.  Disabled
           by default.
