%  Ordinary word processors can create problems when editing eight bit data due
%  to control characters, reserved codes, and differences in line endings. This
%  PostScript-as-language utility does a search and replace on any file having
%  any characters in any combination without any such complications.

%  The routine is especially useful when Post Editing the PDF files of GuruGram 8. 


%  IMPORTANT NOTE: Don Lancaster's file gonzo.ps is required for this program.

|a|0O|b|1rdinary word processors can create problems when editing eight bit data due to control characters, reserved codes, and differences in line endings. Attempting to edit an |/surl |6Acrobat PDF|1|/acrob01  file with an ordinary word processor can cause problems with embedded fonts and encoded Flate Compressed strings.
|h
Instead, a |/surl |6PostScript-as-Language|1|/post01  utility can easily be created that lets you globally search and replace a file of any content without any rude surprises. Such a program is also a good review of PostScript disk file manipulations as well.
|h
I've uploaded a PostScript Search & Replace |/tinton1 |6(|jS|j&|jR|j)|1|/tintoff  utility to our |/surl |6PostScript|1|/post01  library as file |/surl |6SEAREPL.PSL|1|/searepl . Normally, you would bring this file up into a wp or editor, modify it for your own uses, and then send it to |/surl |6Acrobat|1|/acrob01  distiller. Let's look at some key code in this utility\274
|h
I strongly recommend using my |/surl |6gonzo utilities|1|/post01  for most PostScript-as-language development. But for this file, the only utility we only immediately need is the ability to merge two stack-top PostScript strings\274
|3|/shiftin |/burple |/staytint1 |/burplebox3 
/mergestr {2 copy length exch length add string dup dup
4 3 roll 4 index length exch putinterval 3 1 roll exch
0 exch putinterval} def
|1|/shiftout |/aqua |/black 
We start the utility by entering the access data\274
|3|/shiftin |/burple |/staytint1 |/burplebox5 
/diskfileheader (C:\\\\\\\\WINDOWS\\\\\\\\Desktop\\\\\\\\inherit) store
/diskfilesourcename (g9demoyx.pdf) store
/diskfiletargetname (g9demozz.pdf) store
/wuz   ( 4 0 R) store        |t|t|t% string to search
/wilby ( 3 0 R) store        |t|t|t% string to replace
|1|/shiftout |/aqua |/black 
Several minor gotchas here: |/tinton1r |6All PostScript strings MUST include double slashes        |/tinton1r when a single slash is wanted!|1|/tintoff |/black  
) cl

startnewpage

(|/aqua Also, when appropriate be sure to provide a leading space in previous content         |/tinton1 |6wuz|1|/tintoff . And, when using this utility for PDF post processing, it is a very good idea to have the same character counts in |/tinton1 |6wuz|1|/tintoff  and |/tinton1 |6wilby|1|/tintoff . This can eliminate any need for cross reference rebuilding.
|h
We then create our full filenames and convert them to readable and writable PostScript file objects\274
|3|/shiftin |/burple |/staytint1 |/burplebox6 
/sourcefilename diskfileheader diskfilesourcename 
          mergestr store
/targetfilename diskfileheader diskfiletargetname 
          mergestr store
/readfile sourcefilename  (r) file store      |t|t|t        % set input read
/writefile targetfilename (w+) file store     |t|t|t        % set output write
|1|/shiftout |/aqua |/black 
Note that the (w+) tells us to |/tinton1 |6append|1|/tintoff  file info, rather than overwriting it.
|h
There is a 65K limit on PostScript string length, which can easily be exceeded by a PDF or other general file. Thus, several passes might be needed for full processing. Our main processing loop looks like this\274 
|3|/shiftin |/burple |/staytint1 |/burplebox6 
/workstring 60000 string def  |t|t|t% file read workstring
/oops 4000 def                |t|t|t% infinite loop lockout
oops {  readfile workstring readstring        
        {searchandreplace}
        {searchandreplace exit} ifelse
         } repeat
|1|/shiftout |/aqua |/black 
We simply read as much of the file as fits our workstring and then process that piece. An unlikely infinite loop is avoided with |/tinton1 |6oops|1|/tintoff  should something go very wrong with the disk reading process.
|h
The search and replace code could look like this\274
|3|/shiftin |/burple |/staytint1 |/burplebox5 
/searchandreplace {oops { wuz search      |t|t|t     % seek match
{ writefile exch writestring              |t|t|t     % save previous 
pop wilby writefile exch writestring}     |t|t|t     % do replacement
{ writefile exch writestring exit}        |t|t|t     % till nothing left
     ifelse} repeat  } def
|1|/shiftout |/aqua |/black 
Note that several trips through are needed for multiple replacements. The remaining unprocessed string end gets passed back in to do this.
|h
Some extra code is added to the actual utility to report each replacement done or if no replacements took place.
) cl

startnewpage

(Multiple searches and replacements can be done at once by extending the code into a |/tinton1 |6forall|1|/tintoff  loop or a |/tinton1 |6forall|1|/tintoff  dictionary.
|h
Two big gotchas: First make sure wuz and wilby have |/tinton1 |6exactly|1|/tintoff  the same number of characters if you wish to avoid a risky PDF cross reference rebuild. A padding space can usually be added if needed.
|h
Also, make sure wuz and wilby don't take out anything unexpected. Ferinstance, a wuz of |/tinton1 |64 0 R|1|/tintoff  will also take out |/tinton1 |614 0 R|1|/tintoff  or |/tinton1 |624 0 R|1|/tintoff . A leading space cures this particular problem. Also, if your |/tinton1 |6text|1|/tintoff  contains a |/tinton1 |64 0 R|1|/tintoff , add some kerning or something else to prevent an inadvertent substitution.
|c
Altering PDF Transparency
|d
We saw back in |/surl |6GuruGram #8|1|/pstrans  several approaches to creating transparent PostScript artwork by using raw PostScript code sent to Distiller. As of this writing, a PDF post patch seems to still be needed to actually link the correct gstates.
|h
This S&R utility greatly simplifies the process...
|3|/shiftin |/burple |/staytint1 |/burplebox4 
   1. In a word processor, search for all PDF Xobjects.
   2. Write down the wuz and wilby form object numbers.
   3. Enter wuz, wilby and filenames into the S|j&|jR.
   4. Run the S&R program for automatic conversion.
|1|/shiftout |/aqua |/black 
On any repeated editing of the PDF file, simply rerun S&R for an automatic opaque to transparency conversion.
