Re: [xep-support] Flowing text around "curved" images

Hi Michael,

Thanks for your reply. I've uploaded 2 fo files (with pdf's generated)
and the images to my server, the files are:

http://bluelines.org/buslink.fo
http://bluelines.org/buslink.pdf
http://bluelines.org/buslink-works.fo
http://bluelines.org/buslink-works.pdf
http://bluelines.org/img.zip

As you may be able to tell from the file names above, I've had some
success using images which are larger than 1 pixel high, but the same
approach is still not working on the 1-pixel version. Here's a snippet
from the non-working version to demonstrate the underlying code:

<!-- Begin repeated unit -->
<fo:float float="start" clear="both">
  <fo:block margin="0" padding="0" border-width="0" space-before="0"
space-after="0" >
    <fo:external-graphic
        margin="0" padding="0" width="200px" height="1px"
border-width="0"
        space-before="0" space-after="0"
        src="url(img/slice_0.png)" content-width="100%"
content-height="100%"/>
  </fo:block>
</fo:float>
<!-- End repeated unit -->

Many thanks,
--Robin
