3,requirement

 If you create a PNG or JPEG image,you need GD.
 And you may need to compile or to coordinate parameters
 for using GD correctly from Perl or PHP.

 I checked this program on below enviroment

     Linux 2.4.18 (x86)
@@ apache-1.3.27 + PHP-4.3.0(as apache module)
@@ perl 5.6.1
@@ GD 2.0.11
@@ GD.pm 2.06

* CAUTION *
  This program do NOT run on GD 2.0.[0-9] or PHP4.3.[01] bundle
  for GD's bug.
  Please use GD version 1.8.x , 2.0.10 or above.



4,usage

4-1,setup

Set a path to perl or php(in using as cgi).

Change values in setting area if you need.
(If you use in unpacked placement,you don't have to change value.
But you may need to move some files to indicated position.
eg. b.png )


4-2,usage

From browser

qr_img.cgi?d=data[&e=(L,M,Q,H)][&s=int size][&v=(1-40)][&t=(J,H)]
          [&m=(1-16)&n=(2-16)[&o=original data][&p=(0-255)]]

qr_img.php?d=data[&e=(L,M,Q,H)][&s=int size][&v=(1-40)][&t=J]
          [&m=(1-16)&n=(2-16)[&o=original data][&p=(0-255)]]

d : Data you want to encode to QRcode.
    A special letter like '%'.space or 8bit letter must be URL-encoded.
    You cannot omit this parameter.

e : Error correct level
    You can set 'L','M','Q' or 'H'.

    If you don't set,program selects 'M'.

s : module size
    This parameter is no effect in HTML mode.
    You can set a number more than 1.
    Image size depends on this parameter.

    If you don't set,program selects '4' in PNG mode or '8' in JPEG mode.

v : version
    You can set 1-40.
    If you don't set,program automatically selects.

t : image type
    You can set 'J','H' or other.
    'J' : jpeg mode.
    'H' : html mode.(for perl only)
    Other : png mode.

    If you don't set,program select PNG mode.


* CAUTION *
below parameter is experimental.

n : structure append n (2-16)  image No. m of n.
m : structure append m (1-16)  image No. m of n.
p : structure append parity
o : original data (URL-encoded data)  for calculating parity



From command line (for perl only)

example
 $ ./qr_img.cgi d=This+is+a+pen e=L s=3 > qrcode.png

 $ ./qr_img.cgi e=H < data.txt > qrcode.png

 If you input data from STDIN,data don't have to be URL-encoded.
