Eu vi esse fio:Falha na segmentação SWFTools

Quando tentei converter um PDF para SWF usando o pdf2swf, recebi um erro:

/usr/local/bin/pdf2swf /var/www/html/ny-sto-p.watchitoo.com/content/userContent/2/1GRKm/1GRKm.pdf -i -p 5 -o /var/www/html/ny-sto-p.watchitoo.com/content/userContent/2/1GRKm/1GRKm-5.swf
    NOTICE  processing PDF page 5 (720x540:0:0) (move:0:0)
    NOTICE  File contains pbm pictures
    NOTICE  File contains shaded fills
    NOTICE  File contains axial shaded fills
    NOTICE  File contains soft masks
    Segmentation fault

Quando adicionei "-O 1" tudo funcionou:

/usr/local/bin/pdf2swf /var/www/html/ny-sto-p.watchitoo.com/content/userContent/2/1GRKm/1GRKm.pdf -i -O 1 -p 5 -o /var/www/html/ny-sto-p.watchitoo.com/content/userContent/2/1GRKm/1GRKm-5.swf

Qualquer um pode dizer qual é a dose da bandeira "-O 1"? eu procurohttp://swftools.org/ sem sucesso.

Thans, eldad.
