Another way to say it is that only XML can travel along the pipeline.
You are asking Cocoon to call an internal pipeline that returns non-XML,
and have the PNG output flow through your test1 pipeline.
Maybe if you describe what you're trying to accomplish, we can suggest
workarounds, such as a map:redirect or using an svg-to-png serializer.

I try to use coccon:\\ to call the pipeline in another
application, but for html it works fine, but for PNG (using
reader), it couldn't work. I got the error message as
Streaming of an internal pipeline is not possible with a reader.
how can I make it works for PNG file
I have two application under cocoon: test1 test2
in test1 sitemap:
<map:match pattern="ext/**/*.html">
<map:act type="serverpages" src="......">
<map:generate src=" cocoon://test2/*.html"/>
</map:act>
......
</map:match>
<map:match pattern="ext/**/*.png">
<map:generate
src="cocoon://xa-xq/framed/{4}/{5}/{1}/{6}/png/{7}.png "/>
<map:act type="serverpages" src="......">
<map:generate src=" cocoon://test2/*.png"/>
</map:act>
......
</map:match>
in test2 sitemap:
<map:match pattern="*.html">
<map:generate ...>
<map:serializer ..>
</map:match>
<map:match pattern="*.png">
<map:read src="png/{1}.png" mime-type ="image/png"/>
</map:match>
