  1. experiment with caching the tokenised content of Form XObjects

    * Form XObjects are designed to save disk space and parsing time by
      reusing content across pages
    * it doesn't make sense to parse them over and over
    * This is a silly global variable cache to just test the theory and see
      what happens to memory usage and CPU time

  1. these strings are binary, not UTF-8

    * it shouldn't matter, but a test is blowing up on RBX

  1. use Fixnums instead of Strings in our homegrown lexer

    * perftools.rb was showing ~49% of the time extracting text from a large
      sample file was spent in Buffer#prepare_regular_token
    * with this patch that falls to ~40% of time
    * still not great, but a significant improvement
    * this shows the dangers of writing our own lexer and parser. It's
      probably worth investigating if we can switch to a parser gem that
      does a better job

  1. a Hash is not an inline image

    * these specs are getting unwieldly. It will soon be time to break out a
      proper lexer/parser

  1. Merge pull request #48 from bradediger/master

    Properly tokenize "/\n" as an empty PDF name
    committed Feb 19, 2012
  2. Properly tokenize "/\n" as empty PDF name

    Per PDF 32000-1:2008 sec 7.3.5, whitespace in a PDF name must always be
    escaped hexadecimally, and no whitespace may come between the / and the
    start of the name. So a name starting "/\n" should always be tokenized
    as an empty name.

  3. PageState needs public helpers to find resources

    * it encapsulates the search for resources up the stack of nested Form
      XObjects
    committed Feb 19, 2012
  4. ignore xref table entries that point to byte offset 0

    * they can't be correct

  1. update a require call

    committed Feb 18, 2012
  2. Use a PageState object to track state as a page is rendered

    * the tracked state includes current transforms, the current font and
      font size, etc
    * receivers that need to understand state should delegate much of their
      logic to a PageState instance
    * PageTextReceiver is the cannonical example of how to use PageState
