Problem with FOP while exposing the generated images
I need to display the images on pdf document. I am using FOP 0.20 for
generating the pdf documents. In order to display the image, i had to
write an Xalan Java Extension to decode the base 64 data and create an
image on file system. This extension returns the absolute path for the
image. Following is my snippet of xslt for the same...
<fo:table-cell padding-top="0.05cm" padding-left="0.07cm">
<fo:block text-align="left" border-bottom-style="solid"
border-bottom-width="0.02cm" font-weight="bold">
<xsl:variable
name="signature" select="//recipient//encodedBytes"/>
<xsl:variable name="sign"
select="converter:ConversionHelper.getDecodedData($signature)"/>
<fo:external-graphic src="{$sign}"
content-width="50px" content-height="7px"/>
</fo:block>
</fo:table-cell>
The above code works fine on Windows. This generates the images and the
same are being shown on the PDF.
Problem is that on UNIX, this extension creates the image successfully.
But cannot display on PDF document. Even if I create the image on window
thru the extension and FTP to UNIX and use the same image on external
graphic, it cannot display the image on PDF. If I save the generated
image on windows to another extension or copy to different name and FTP
to UNIX and use that in external graphic, that would show clearly. Did
any one see this problem before?
Thanks,
Kishore.

Why so complicated? Why don't you just use RFC2397 data URLs? There is
support for them built-in to FOP 0.93, and for FOP 0.20.5 you'll find an
add-on on the fop-users mailing list archives.
