Re: [Swftools-common] Problem converting a pdf to swf

[James White]

Greetings,
    Let me try one more time and I'll try to be clearer.  Below is the output from a set of commands.

    If I convert the file "1-C.pdf" using the command below the resulting swf file contains the text from the OCR layer in the PDF. 

pdf2swf 1-C.pdf 1-C.swf -T 9 -f

NOTICE  File contains pbm pictures
.......
NOTICE  Writing SWF file 1-C.swf

    I can extract the strings in the resulting swf and it contains all the OCR'ed strings.

swfstrings 1-C.swf > 1-C.txt
wc 1-C.txt

 2236  2236 14033 1-C.txt

    However the image portion of the resulting swf file is not correct.

swfrender 1-C.swf -o 1-C.png

    I can create a swf file with a correct image using the commmand below:

pdf2swf 1-C.pdf 1-C-O1.swf -T 9 -f -O1

NOTICE  processing PDF page 1 (612x780:0:0) (move:0:0)
.......
NOTICE  Writing SWF file 1-C-O1.swf

    However the resulting swf file doesn't have any strings in it.

swfstrings 1-C-O1.swf > 1-C-O1.txt
wc 1-C-O1.txt

0 0 0 1-C-O1.txt

    I'm looking for a way to get the correct correct image portion from the "1-C-O1.swf" and maintain the strings that are in "1-C.swf".

    I have put all the files in : http://dl.dropbox.com/u/5051173/cmsd.zip


   Thanks again for your time and effort.

Greetings,
     I have a similar problem (I think) and I'm hoping someone can give me
some insight into fixing it.  I have a number of PDF document that I need to
convert (on demand) to swf and view.  I'm using FlexPaper
(http://flexpaper.devaldi.com/) to view swf files.  An important feature is
to be able to search the document.  A number of these PDF documents are
scanned documents with an OCR'ed text in them.  If I use "pdf2swf input.pdf
-o output.swf " all is well.  I can view the embedded OCR results using
"swfstrings" and the resulting swf file is searchable in the FlexPaper
viewer.   However there are a number of PDF files that don't render properly
with out using the "-O1" or "-s poly2bitmap" switch.
    

Take a step back.  Are these PDF's themselves properly searchable?   If whatever
you are using to create the PDFs can't make sense of the OCR'd fonts,
then they'll
simply be rendered as graphics in the PDF.   Test the PDF with some of the
command-line utilities from the xpdf distribution,  such as pdftotext.  See what
happens.

You may also have fonts that xpdf can't make sense of.  Using the -vvv, verbose
option during conversion, and examining the output, should give you a clue as to
what is happening.

HTH

Chris.
