in reply to OCR Code

Somehow i need to generate OCR code

So, after piecing together all of your posts in this thread, it seems you want to be able to create a PDF document that uses a font, such as OCR-A or OCR-B, that is designed for reading by OCR systems.

You don't explain how you generate your PDF now. If you are using PDF::API2, I think it allows you to use any TrueType Font you want. If you aren't using it, I suggest you review it. I've not used it much myself (I've played a bit), but I've heard good things from people who have. There are some examples available at http://www.penguin.at0.net/~fredo/files/ which you may find helpful.

      Can you show us your code that uses PDF::API2?

      It should be a simple matter of changing or adding a font definition to your code.

      You should have a font definition in you want to look something like:

      my $doc = PDF::API2->new( -file => 'mypdf.pdf' );
my $page = $doc->page;
my $txt = $page->text;

my $font = $doc->corefont('OCR A',1); # this font name may be incorrec
+t.. 
$font->encode('latin1');

$txt->font($font,10);
$txt->lead(10);
$txt->text('Print to PDF file in the font set above');

# ....

        I run the following code for testing. Basically it's same piece of code using OCR_A font.

        It's giving me below error. 

         

use PDF::API2;

my $doc = PDF::API2->new( -file => 'mypdf.pdf' );
my $page = $doc->page;
my $txt = $page->text;

my $font = $doc->corefont('OCR_A',1); # this font name may be incorrec
+t.. 
$font->encode('latin1');

$txt->font($font,10);
$txt->lead(10);
$txt->text('Print to PDF file in the font set above');
