Okay bestie, welcome to the Font::TTF::Head(3) page from the User Contributed Perl Documentation 💖. We're talking about the head table for a TTF font, and it's giving foundational main-character energy.

🌸 NAME 🌸

Font::TTF::Head — the head table for a TTF font. That's the whole assignment, no extra lore.

✨ DESCRIPTION ✨

This is a very basic table with just instance variables as described in the TTF documentation, using the same names. One of the most commonly used is unitsPerEm. Slay, honestly.

🎀 INSTANCE VARIABLES 🎀

The head table has no internal instance variables beyond those common to all tables and those specified in the standard:

  • version
  • fontRevision
  • checkSumAdjustment
  • magicNumber
  • flags
  • unitsPerEm
  • created
  • modified
  • xMin
  • yMin
  • xMax
  • yMax
  • macStyle
  • lowestRecPPEM
  • fontDirectionHint
  • indexToLocFormat
  • glyphDataFormat

The two dates are held as an array of two unsigned longs (32-bits). Cute, compact, very demure.

💅 METHODS 💅

🌟 $t->read

Reads the table into memory thanks to some utility functions. The utility functions are doing the behind-the-scenes labor, and we respect them for it.

🌟 $t->out($fh)

Writes the table to a file either from memory or by copying. If it's in memory (which is usually the case), the checkSumAdjustment field is set to 0 as per the default if the file checksum is not to be considered.

🌟 $t->minsize()

Returns the minimum size this table can be. If it is smaller than this, then the table must be bad and should be deleted or whatever. The “or whatever” is carrying so much chaotic energy 😭.

🌟 $t->XML_element($context, $depth, $key, $value)

Handles date process for the XML exporter. That's the vibe.

🌟 $t->update

Updates the head table based on the glyph data and the hmtx table.

🌟 $t->getdate($is_create)

Converts font modification time (or creation time if $is_create is set) to a 32-bit integer as returned from time(). Returns undef if the value is out of range, either before the epoch or after the maximum storable time. Respect the range, bestie.

🌟 $t->setdate($time, $is_create)

Sets the time information for modification (or creation time if $is_create is set) according to the 32-bit time information.

👑 BUGS 👑

None known. Iconic behavior, honestly.
