RE: decoding base64 tiff files embedded in XML
From: John Moylan [mailto:[EMAIL PROTECTED]] Hi, I'm new to this list and to Cocoon2, however I need to develop an application which transforms NewsML feeds into regular HTML for browsing. Easy you say, right? Anyway the part I'm am having difficulty with is in converting base64 embedded tiff images into png on the fly. I don't know much about Java. I have a one liner in Perl which decodes the tiff from the shell prompt: perl -MMIME::Base64 -ne 'print decode_base64($_)' /home/john/tiff.64 j.tiff and an one liner which uses imagemagick's convert from the shell: convert j.tiff j.png Can I somehow use turn one or both, of these one liners into sitemap generators (is that the right term.) There are many approaches you can take. Depends on what level of reusability of your components you want to achieve and details of input format (never seen NewsML...). If input is XML with data and images intermixed, use fragment extractor. If input is XML, one way is to write serializer which takes input XML with base64 encoded image and outputs image. It can also convert image from tiff to png (using some Java image manipulation library). If input is not XML, then you should write reader, which will read base64, decode it, and write image as output (converting as necessary). Vadim or is their any easier/better way. I can preprocess my XML files from the command line, but that does not seem like a very elegant/manageable solution. - Please check that your question has not already been answered in the FAQ before posting. http://xml.apache.org/cocoon/faq/index.html To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: decoding base64 tiff files embedded in XML
there is a transformer that removes some nodes from XML and changes them with links. I think you could use this aproach. For the actual transformation I imagine you can use some library that does that without a lot of effort... sun used to have a java imaging package... You could code a sitemap element (perhaps a reader) to call shell commands, but you would loose all portability and gain dependencies on external stuff(perl,etc..) -Original Message- From: John Moylan [mailto:[EMAIL PROTECTED]] Sent: quinta-feira, 13 de Junho de 2002 15:09 To: [EMAIL PROTECTED] Subject: decoding base64 tiff files embedded in XML Hi, I'm new to this list and to Cocoon2, however I need to develop an application which transforms NewsML feeds into regular HTML for browsing.

Re: decoding base64 tiff files embedded in XML
Not knowing how to write a reader or a serializer I think I'm going to have to run a batch process, something like the following in BASH/Perl and sabletron (because it was installed.) DIR=/usr/local/jakarta-tomcat-3.3.1/webapps/cocoon/content ls $DIR/*.xml /tmp/xmlfiles for i in `cat /tmp/xmlfiles` do sabcmd $DIR/base64tiff.xsl $i $i.64tiff perl -MMIME::Base64 -ne 'print decode_base64($_)' $i.64tiff $i.tiff convert $i.64tiff $i.jpg done My stylesheet -simple ?xml version=1.0? xsl:stylesheet version=1.0 xmlns:xsl=http://www.w3.org/1999/XSL/Transform; xsl:template match=/ xsl:value-of select=//ContentItem/Encoding[@Notation='base64']/DataContent/ /xsl:template /xsl:stylesheet However, all of my tiff base64 files have ?xml version=1.0 encoding=UTF-8? prepended to them - I'm curios as to wether or not their is a way to avoid this at the top of xsl processed files using standard xslt techniques?
