+{\bf NOTE:} \LUATEX\ 0.74.0 is the first version with Lua 5.2, and
+this is used without any patches to the core, which has some side
+effects. In particular, Lua's \type{tonumber()} may return values in
+scientific notation, thereby confusing the \TEX\ end of things when it
+is used as the right-hand side of an assignment to a \type{\dimen}
+or \type{\count}.
+
+{\bf NOTE:} Also in \LUATEX\ 0.74.0 (this is a change in Lua 5.2),

+loaded at the same time (which will typically happen on Win32, because
+there is one Lua 5.2 inside luatex, and another will likely be linked
+to the \type{dll} file of the module itself). We plan to fix that later

+\section{The \luatex{pdfscanner} library (new in 0.72.0)}
+
+The \luatex{pdfscanner} library allows interpretation of PDF content streams
+and \type{/ToUnicode} (cmap) streams. You can get those streams from the
+\luatex{epdf} library, as explained in an earlier section. There is only
+a single top|-|level function in this library:
+
+\startfunctioncall
+pdfscanner.scan (<Object> stream, <table> operatortable, <table> info)
+\stopfunctioncall
+
+The first argument, \type{stream}, should be either a PDF stream
+object, or a PDF array of PDF stream objects (those options comprise
+the possible return values of \type{<Page>:getContents()}
+and \type{<Object>:getStream()} in the \type{epdf} library).
+
+The second argument, \type{operatortable}, should be a Lua table where
+the keys are PDF operator name strings and the values are Lua
+functions (defined by you) that are used to process those
+operators. The functions are called whenever the scanner finds one
+of these PDF operators in the content stream(s). The functions are
+called with two arguments: the \type{scanner} object itself, and
+the \type{info} table that was passed are the third argument
+to \type{pdfscanner.scan}.
+
+Internally, \type{pdfscanner.scan} loops over the PDF operators in the
+stream(s), collecting operands on an internal stack until it finds a
+PDF operator. If that PDF operator's name exists
+in \type{operatortable}, then the associated function is
+executed. After the function has run (or when there is no function to
+execute) the internal operand stack is cleared in preparation for the
+next operator, and processing continues.
+
+The \type{scanner} argument to the processing functions is needed
+because it offers various methods to get the actual operands from the
+internal operand stack. The most important of those functions is
+\type{}
+
+A simple example of processing a PDF's document stream
+could look like this:
+
+\starttyping
+function Do (scanner, info)
+ local val = scanner:pop()
+ local name = val[2] -- val[1] == 'name'
+ print (info.space ..'Use XObject '.. name)
+ local resources = info.resources
+ local xobject = resources:lookup("XObject"):getDict():lookup(name)
+ if (xobject and xobject:isStream()) then
+ local dict = xobject:getStream():getDict()
+ if dict then
+ local name = dict:lookup('Subtype')
+ if name:getName() == 'Form' then
+ local newinfo = { space = info.space .. " " ,
+ resources = dict:lookup('Resources'):getDict() }
+ pdfscanner.scan(xobject, operatortable, newinfo)
+ end
+ end
+ end
+end
+operatortable = {Do = Do}
+
+doc = epdf.open(arg[1])
+pagenum = 1
+while pagenum <= doc:getNumPages() do
+ local page = doc:getCatalog():getPage(pagenum)
+ local info = { space = " " , resources = page:getResourceDict()}
+ print ('Page ' .. pagenum)
+ pdfscanner.scan(page:getContents(), operatortable, info)
+ pagenum = pagenum + 1
+end
+\stoptyping
+
+This example iterates over all the actual content in the PDF, and
+prints out the found XObject names. While the code demonstrates quite
+some of the \type{epdf} functions, let's focus on the type
+\type{pdfscanner} specific code instead.
+
+From the bottom up, the line
+
+\starttyping
+ pdfscanner.scan(page:getContents(), operatortable, info)
+\stoptyping
+
+runs the scanner with the PDF page's top-level content.
+
+The third argument, \type{info}, contains two entries: \type{space} is
+used to indent the printed output, and \type{resources} is needed so
+that embedded \type{XForms} can find their own content.
+
+The second argument, \type{operatortable} defines a processing function
+for a single PDF operator, \type{Do}.
+
+The function \type{Do} prints the name of the current XObject, and
+then starts a new scanner for that object's content stream, under the
+condition that the XObject is in fact a \type{/Form}. That nested
+scanner is called with new \type{info} argument with an
+updated \type{space} value so that the indentation of the output nicely
+nests, and with an new \type{resources} field to help the next
+iteration down to properly process any other, embedded XObjects.
+
+Of course, this is not a very useful example in practise, but for the
+purpose of demonstrating \type{pdfscanner}, it is just long enough.
+It makes use of only one \type{scanner} method: \type{scanner:pop()}.
+That function pops the top operand of the internal stack, and returns
+a lua table where the object at index one is a string representing
+the type of the operand, and object two is its value.
+
+The list of possible operand types and associated lua value types is:
+
+\starttabulate[|lT|p|]
+\NC integer \NC <number> \NC \NR
+\NC real \NC <number> \NC \NR
+\NC boolean \NC <boolean> \NC \NR
+\NC name \NC <string> \NC \NR
+\NC operator \NC <string> \NC \NR
+\NC string \NC <string> \NC \NR
+\NC array \NC <table> \NC \NR
+\NC dict \NC <table> \NC \NR
+\stoptabulate
+
+In case of \type{integer} or \type{real}, the value is always
+a Lua (floating point) number.
+
+In case of \type{name}, the leading slash is always stripped.
+
+In case of \type{string}, please bear in mind that PDF actually
+supports different types of strings (with different encodings) in
+different parts of the PDF document, so may need to reencode some of
+the results; \type{pdfscanner} always outputs the byte stream without
+reencoding anything. \type{pdfscanner} does not differentiate between
+literal strings and hexidecimal strings (the hexadecimal values are
+decoded), and it treats the stream data for inline images as a string
+that is the single operand for \type{EI}.
+
+In case of \type{array}, the table content is a list of \type{pop}
+return values.
+
+In case of \type{dict}, the table keys are PDF name strings
+and the values are \type{pop} return values.
+
+\blank
+
+There are few more methods defined that you can ask \type{scanner}:
+
+\starttabulate[|lT|p|]
+\NC pop \NC as explained above\NC \NR
+\NC popNumber \NC return only the value of a \type{real} or \type{integer}\NC \NR
+\NC popName \NC return only the value of a \type{name} \NC \NR
+\NC popString \NC return only the value of a \type{string} \NC \NR
+\NC popArray \NC return only the value of a \type{array} \NC \NR
+\NC popDict \NC return only the value of a \type{dict} \NC \NR
+\NC popBool \NC return only the value of a \type{boolean} \NC \NR
+\NC done \NC abort further processing of this \type{scan()} call\NC \NR
+\stoptabulate
+
+The \type{popXXX} are convenience functions, and come in handy when
+you know the type of the operands beforehand (which you usually do, in
+PDF). For example, the \type{Do} function could have used \type{local
+name = scanner:popName()} instead, because the single operand
+to the \type{Do} operator is always a PDF name object.
+
+The \type{done} function allows you to abort processing of a stream
+once you have learned everything you want to learn. This comes in handy
+while parsing \type{/ToUnicode}, because there usually is trailing
+garbage that you are not interested in. Without \type{done}, processing
+only end at the end of the stream, possibly wasting CPU cycles.
