Hi,
what I'm trying to do is to transform this :
xml ...
imagehttp://sourceurl/path/image.jpg/image
to
http://cocoonurl/image.jpg where this image is resized.
You need something like this:
map:match pattern=images/**
map:read type=image-op-scale
src=cached:http://sourceurl/{1}?cocoon:cache-expires=60cocoo
n:cache-name=cached-images/
/map:match
Don't you think it would be much easier to use mod_cache between the browser
and cocoon to handle the caching of binary files like these? Furthermore,
making sure the reader gets a correct expires value in the component
configuration makes the images properly cacheable by browsers too (if mod_cache
honours the ttl headers of cocoon of course)
So, for example, in your components, declare:
map:reader name=image src=org.apache.cocoon.reading.ImageReader
logger=sitemap.reader.image pool-max=32 pool-min=1 pool-grow=4
parameter name=expires value=8640/
/map:reader
And have a matcher
map:match pattern=readImage/*/*/**
map:read src={2} type=image
map:parameter name=width value={1}/
map:parameter name=height value={2}/
/map:read
/map:match
This should do the trick. If you insist on caching it in cocoon as well, of
course you can use the wrapped src suggestion of Grzegorz
Regards Ard
This way you will get proxy-like behaviour thanks to Cocoon's
cached: protocol thus avoiding re-downloading original images
again and again.
For description of cached source, take a look at:

RE: Image treatment
Could you give more hints about what you are trying to achieve exactly. To my knowledge, it should be possible to read with any protocol known to Cocoon, but where should the result go, once transformed? And are you trying to process multiple images in one pass? Try transforming just one for starters.. Kind regards, Geert Drs. G.P.H.

From: lfhc [mailto:[EMAIL PROTECTED] Sent: maandag 18 juni 2007 13:21 To: users@cocoon.apache.org Subject: Image treatment Hi, I needed to have some image treatment done, and I've been looking through ImageReader. Yet, my assumption is that this module only gets images from a filesystem, and I needed to get them through an http source. For example, I have a content source for news, that gives me an url for the images uploaded. With that content source, I want to build html pages, but that image url cannot be the original one, but one from cocoon, and, if possible, have some resizing done. Can anyone point me in the right direction please?
