There are several scaling attributes you can use, as documented here:

Hi

I also have a problem with images in pdf.
It completely ignores my imagedata commends. All the pictures are totally unscaled, bigger than 100% and distorted.
I've tried various image formats (png, gif, jpg) and units (cm, px, pc, %). Nothing works.
Without giving units the images are also unscaled.

I've also used scalefit="1", width="100%" & contentwidth="100%". Nothing works.

What can I do?

Thanks in advance!

Hi,

The following attributes work for me, for imagedata:
  width="100%" scalefit="1"

(and nothing else, no units, no nothing).


As per http://www.sagehill.net/docbookxsl/ImageSizing.html

" scalefit
  If set to a value of 1, then the processor will scale the
  graphic proportionally to fit the allowed area. The image
  is scaled to fit the specified width or depth viewport
  dimension, whichever fills up first.

  [...]

  To keep a graphic for printed output at its natural size
  unless it is too large to fit the available width, in which
  case shrink it to fit, use scalefit="1", width="100%" and
  contentdepth="100%" attributes."


Regards,
EB

Can you describe what FO processor you are using?  And perhaps include a
very short document showing how you are marking it up?  That would enable us
to diagnose the problem.

I'm using the Apache FOP FO-Processor.

This is my source code:

<mediaobject>
<imageobject>
<imagedata scalefit="1" width="100%" contentwidth="100%" fileref="figure/pic1.png" format="PNG"/>
</imageobject>
</mediaobject>

I have attached the unscaled image (in pdf) and the original image.

Actually, we would need the version of FOP, because the handling of graphics
in version 0.20.5 was very limited, and much improved in the 0.94 line of
development.  If you are using 0.20.5, you should upgrade to the latest
version.

I've tried it also without using contentwidth, but it also doesn't work. It's the same result as before. Nothing has changed.

Bob Stayton wrote:

The problem is you are using contentwidth="100%". A percentage in the
contentwidth attribute means to scale the image itself to a percentage of
the intrinsic image size. So setting contentwidth to 100% effectively means
you do not want it scaled. Not only that, contentwidth takes precedence
over scalefit="1" in the stylesheets. So just remove contentwidth and your
graphic should scale to the width of page based on the other two attributes.
See this page for more details on image scaling attributes:
