NAME

       Remind::PDF - Render a month's worth of Remind data to PDF

CLASS METHODS

   Remind::PDF->create_from_stream($in, $specials_accepted)
       This method reads data from an open file handle $in.  $specials_accepted is a hashref of
       SPECIAL reminder types to accept; the key is the name of the SPECIAL (all lower-case) and
       the value should be 1.  Any SPECIAL reminders not in the hash are ignored.

       This function returns a two-element array: "($obj, $err)".  On success, $obj will be a
       "Remind::PDF" object and $err will be undef.  On failure, $obj will be undef and $err will
       be an error message.

   Remind::PDF->create_from_hash($hash, $specials_accepted)
       This method takes data from a hash $hash, which must be one month's worth of data from
       "remind -ppp" output.  $specials_accepted is a hashref of SPECIAL reminder types to
       accept; the key is the name of the SPECIAL (all lower-case) and the value should be 1.
       Any SPECIAL reminders not in the hash are ignored.

       This function returns a two-element array: "($obj, $err)".  On success, $obj will be a
       "Remind::PDF" object and $err will be undef.  On failure, $obj will be undef and $err will
       be an error message.

INSTANCE METHODS

   read_one_month($in, $first_line, $specials_accepted)
       This function reads one month's worth of data from the file handle $in.  $first_line is
       the line that was read from $in just before calling this function.  $specials_accepted is
       a hashref as documented above.

       The return value is the same "($obj, $err)" two-element array as "create_from_stream"
       returns.

   read_one_month_p($in, $specials_accepted)
       This function reads one month's worth of data from the file handle $in, assuming the
       original "remind -p" format.  $specials_accepted is a hashref as documented above.

       The return value is the same "($obj, $err)" two-element array as "create_from_stream"
       returns.

   parse_oldstyle_line ($line)
       This method parses an old-style "remind -p" line and returns a hashref containing some or
       all of the hash keys found in the newer "remind -pp" JSON output.

   setup_daymap
       Set up the array that maps ($row, $col) to day number (or -1 for rows/cols out of range.)

   read_one_month_pp($in, $specials_accepted)
       This function reads one month's worth of data from the file handle $in, assuming the
       "remind -pp" partial-JSON format.  $specials_accepted is a hashref as documented above.

       The return value is the same "($obj, $err)" two-element array as "create_from_stream"
       returns.

   accept_special($hash, $specials_accepted)
       Given a hashref $hash consisting of one entry parsed from the "remind -p" stream and a
       $specials_accepted hash, return 1 if we should include this entry in the calendar or 0 if
       not.

   find_last_special($special, $entries)
       Given an array of Reminder entries, find the last $special-type SPECIAL in the array.
       Return the entry if one was found or undef if not.

   render($cr, $settings)
       Render a calendar for one month.  $cr is a Cairo drawing context, and $settings is a
       settings hash passed in by the caller.  See the source code of "rem2pdf" for the contents
       of $settings

   draw_row($cr, $settings, $so_far, $row, $start_day, $start_col)
       Draw a single row in the calendar.  $cr is a Cairo drawing context and $settings is the
       settings hash passed to "render".  $so_far is the Y-coordinate of the top of the row;
       drawing starts at this coordinate.  $start_day is the day of the month at which the row
       starts and $start col is the column number (0-6) at which to start drawing from $start_day

       Returns the Y coordinate at which to start drawing the next calendar row.

   col_box_coordinates($so_far, $col, $height, $settings)
       Returns a four-element array "($x1, $y1, $x2, $y2)" representing the bounding box of the
       calendar box at column $col (0-6).  $height is the height of the box and $settings is the
       settings hashref passed to "render".

   draw_day($cr, $settings, $so_far, $day, $col, $height)
       Renders a single day's worth of reminders.  $cr is a Cairo drawing context and $settings
       is the settings hash passed to "render".  $so_far is the Y-coordinate of the top of the
       box and $col is the column number.

       $height is the height of the box.  If $height is passed in as zero, then do not actually
       render anything... instead, compute how high the box should be.  If $height is non-zero,
       then it is the height of the box.

       Returns the height required for the calendar box.

   draw_daynames($cr, $settings, $so_far)
       Draw the weekday names heading.  $cr is a Cairo drawing context and $settings is the
       settings hash passed to "render".  $so_far is the Y-coordinate of the top of the row;
       drawing starts at this coordinate.

       Returns the Y coordinate at which to start drawing the first calendar row.

   draw_title($cr, $settings)
       Draw the title ("Monthname Year") at the top of the calendar.  $cr is a Cairo drawing
       context and $settings is the settings hash passed to "render".

       Returns the Y coordinate at which to start drawing the row containing the weekday names.

   draw_small_calendar($cr, $x, $y, $width, $height, $settings, $month, $days, $start_wkday)
       Draw a small calendar on the Cairo context $cr.  The top left-hand corner of the box is at
       "($x, $y)" and the size of the box is "($width, $height").  $settings is the settings
       hashref passed to "render".  $month is the name of the month to draw and $days is the
       number of days in the month.  Finally, $start_wkday is the weekday (0=Sunday, 6=Saturday)
       on which the month starts

NAME

       Remind::PDF::Multi - A container for multiple months' worth of calendar data

DESCRIPTION

       The "remind -ppp" output consists of a JSON array with each element representing one
       month's worth of reminders.  "Remind::PDF::Multi" reads this output and returns an
       instance of itself containing an array of "Remind::PDF" objects, one object for each
       month.

CLASS METHODS

   Remind::PDF::Multi->create_from_stream($in, $specials_accepted)
       This method reads data from an open file handle $in.  $specials_accepted is a hashref of
       SPECIAL reminder types to accept; the key is the name of the SPECIAL (all lower-case) and
       the value should be 1.  Any SPECIAL reminders not in the hash are ignored.

       This function returns a two-element array: "($obj, $err)".  On success, $obj will be a
       "Remind::PDF::Multi" object and $err will be undef.  On failure, $obj will be undef and
       $err will be an error message.

   Remind::PDF::Multi->create_from_json($json, $specials_accepted)
       This method takes data from a JSON string <$json>.  $specials_accepted is a hashref of
       SPECIAL reminder types to accept; the key is the name of the SPECIAL (all lower-case) and
       the value should be 1.  Any SPECIAL reminders not in the hash are ignored.

       This function returns a two-element array: "($obj, $err)".  On success, $obj will be a
       "Remind::PDF::Multi" object and $err will be undef.  On failure, $obj will be undef and
       $err will be an error message.

INSTANCE METHODS

   render($cr, $settings)
       Iterate through all the "Remind::PDF" objects and call their "render" methods.  This
       method renders as many months worth of calendar data as were read from the "remind -ppp"
       stream
