docbook-apps

I've been trying to get inline images in a PDF file to appear
correctly but they always seem to big. I've been following the advice
in Bob's excellent book (also available at
http://www.sagehill.net/docbookxsl/ImageSizing.html) and using

<inlinemediaobject>
<imageobject>
<imagedata fileref="images/image.png" format="PNG" scalefit="1"
width="100%" contentdepth="100%"/>
</imageobject>
</inlinemediaobject>

So far, no luck; they appear to be scaled bigger than they actually
are (the actual image is 36 pixels wide by 14 pixels high and has a
resolution of 72 dpi -- the image appears roughly 1.5 times larger
than actual when looking at the document on screen or printed out).
I'm using the XSL 1.72.0 stylesheets and FOP 0.93 on Windows.

Any other ideas on configuration? Maybe I need to include something
about resolution in the FOP configuration file?

Thanks,
tgm

I have heard that fop is not so good at obeying the scaling commands.
I can't remember where, though.

I'm currently working with a custom stylesheet I wrote from scratch (not
DocBook) to generate FO from an XML document, and I'm using FOP v0.93. I've
found that the image scaling does work. If I use the following FO:

<fo:external-graphic src="image.jpg" width="100px"
content-width="scale-to-fit"/>

then the image is scaled properly to the given width, and the proportions
remain intact.

I haven't looked at the FO produced by the DocBook stylesheets, so this
doesn't necessarily answer the original poster's question, but FOP can do
image scaling in this manner.

Hrm, maybe I was thinking of fop 0.2x

I did (re)find more info on DocBook's scaling attributes:

Was this for an image that is 100 pixels wide Colin? Or was the
example meant to say ..."width=100%"...?

Thanks,

No, I meant pixels, as I wrote. It works this way for an image of any size;
if my source image is 800px wide and 600px tall, then the FO

<fo:external-graphic src="image.jpg" width="100px"
content-width="scale-to-fit"/>

will render my image as 100px wide and 75px tall (preserving the
proportions).
