ARC4 encrypt a text string

initialize the ARC4 encryption

class constructor this will start a new document

extract an integer from a position in a byte stream

do a part of the calculation for sorting out the justification of the text

wrapper function for PRVTcheckTextDirective1

checks if the text stream contains a control directive if so then makes some changes and returns the number of characters involved in the directive this has been re-worked to include everything neccesary to fins the current writing point, so that the location can be sent to the callback function if required if the directive does not require a font change, then $f should be set to 0

given a start position and information about how text is to be laid out, calculate where on the page the text will end

add content to the currently active object

create a labelled destination within the document

add an image into the document, from a GD object this function is not all that reliable, and I would probably encourage people to use the file based functions

add content to the documents info object

add a link in the document to an internal destination (ie. within the document)

add a JPEG image into the document, from a file

common code used by the two JPEG adding functions

add a link in the document to an external URL

used to add messages for use in debugging

after an object has been created, it wil only show if it has been added, using this function.

add a PNG image into the document, from a file this should work with remote files

add text to the document, at a specified location, size and angle on the page

add text to the page, but ensure that it fits within a certain width if it does not fit then put in as much as possible, splitting at word boundaries and return the remainder.

should be used for internal checks, not implemented as yet

close an object

Get current font

draw a bezier curve based on 4 control points

draw an ellipse note that the part and filled ellipse are just special cases of this function

initialize the encryption for processing a particular object

draw a filled ellipse

a filled rectangle, note that it is the width and height of the rectangle which are the secondary paramaters, not the coordinates of the upper-right corner

filter the text, this is applied to all text just before being inserted into the pdf document it escapes the various things that need to be escaped, and so on

function for the user to find out what the ID is of the first page that was created during startup - useful if they wish to add something to it later.

return the font decender, this will normally return a negative number if you add this number to the baseline, you get the level of the bottom of the font it is in the pdf user units

return the height in units of the current font in the given size

calculate how wide a given text string will be on a page, at a given size.

draw a line from one set of coordinates to another

calculate the 16 byte version of the 128 bit md5 digest of the string

intialize a new document if this is called on an existing document results may be unpredictable, but the existing document would be lost at minimum this function is called automatically by the constructor function

add a new page to the document this also makes the new page the current active object

an action object, used to link to URLS initially

an annotation object, this will add an annotation to the current page.

define the document catalog, the overall controller for the document

the contents objects hold all of the content which appears on pages

destination object, used to specify the location for the user to jump to, presently on opening

encryption object.

an object to hold the font description

a font descriptor, needed for including additional fonts

the font encoding

Add object to hold Function properties Only partial support for type 0, 3 and 4

an image object, will be an XObject in the document, includes description and data

define the document information

define the outlines in the doc, empty for now

a page object, it also creates a contents object to hold its contents

object which is a parent to the pages in the document

Add object to hold pattern properties

the document procset, solves some problems with printing to old PS printers

Add object to hold shading properties

set the viewer preferences

open the font file and return a php structure containing it.

specify where the document should open when it first starts

make a loose object, the output will go into this object, until it is closed, then will revert to the current one.

return the pdf stream as a string returned from the function

draw a part of an ellipse

draw a polygon, the syntax for this is similar to the GD polygon command

draw a rectangle, note that it is the width and height of the rectangle which are the secondary paramaters, not the coordinates of the upper-right corner

open an existing object for editing

restore a previously saved state

this will be called at a new page to return the state to what it was on the end of the previous page, before the stack was closed down This is to get around not being able to have open 'q' across pages

if the font is not loaded then load it and make the required object else just make it the current font the encoding array can contain 'encoding'=> 'none','WinAnsiEncoding','MacRomanEncoding' or 'MacExpertEncoding' note that encoding='none' will need to be used for symbolic fonts and 'differences' => an array of mappings between numbers 0->255 and character names.

sets the colour for fill operations

sets up the current font, based on the font families, and the current text state note that this system is quite flexible, a font can be completely different to a font, and even will have to be defined within the family to have meaning This function is to be called whenever the currentTextState is changed, it will update the currentFont setting to whatever the appropriatte family one is.
