$currentStrokeColour current colour for stroke operations (lines etc.)
$currentLineStyle current style that lines are drawn in
$stateStack an array which is used to save the state of the document, mainly the colours and styles it is used to temporarily change to another state, the change back to what it was before
$nStateStack number of elements within the state stack
$numPages number of page objects within the document
$stack object Id storage stack
$nStack number of elements within the object Id storage stack
$looseObjects an array which contains information about the objects which are not firmly attached to pages these have been added with the addObject function
$addLooseObjects array contains infomation about how the loose objects are to be added to the document
$infoObject the objectId of the information object for the document this contains authorship, title etc.
$numImages number of images being tracked within the document
$options an array containing options about the document it defaults to turning on the compression of the objects
$firstPageId the objectId of the first page of the document
$wordSpaceAdjust used to track the last used value of the inter-word spacing, this is so that it is known when the spacing is changed.
$procsetObjectId the object Id of the procset object
$fontFamilies store the information about the relationship between font families this used so that the code knows which font is the bold version of another font, etc.
$currentTextState track if the current font is bolded or italicised
$messages messages are stored here during processing, these can be selected afterwards to give some useful debug information
$arc4 the ancryption array for the document encryption is stored here
$arc4_objnum the object Id of the encryption information
$fileIdentifier the file identifier, used to uniquely identify a pdf document
$encrypted a flag to say if a document is to be encrypted or not
$encryptionKey the ancryption key for the encryption of all the document content (structure is not encrypted)
$callback array which forms a stack to keep track of nested callback functions
$nCallback the number of callback functions in the callback array
$destinations store label->id pairs for named destinations, these will be used to replace internal links done this way so that destinations can be defined after the location that links to them
$checkpoint store the stack for the transaction commands, each item in here is a record of the values of all the variables within the class, so that the user can rollback at will (from each 'start' command) note that this includes the objects array, so these can be large.
