Problem with inserting images
Hi everyone,
I just started using XSL-FO and fop. I am trying to generate a pdf file
which contains jpg files. Those images are always inserted in a parent
component (I guess something like a viewport). I need to set a height
for this viewport (view_height).
I need to be able to display them in the following 2 cases:
case 1: the image's height is greater than view_height. In that case
the image has to scale in order to fit in its view_height. I succeeded
in doing that. I did something like (where 100px is the height of my
viewport):
<fo:block background-color="white" text-align="center">
<fo:external-graphic content-height="100px" height="100px"
src="url(image.jpg)"/>
</fo:block>
case 2: if view_height is greater than the image's height, then I want
to display the image at its actual size and display it at the center of
its viewport. Doing something like this does not work:
<fo:block background-color="white" text-align="center">
<fo:external-graphic content-height="25px" height="100px"
src="url(image.jpg)"/>
</fo:block>

Just be careful that the fo:external-graphic is the only child of the
fo:block in question... Every new line of text entered in there (or any
fo:inline, which might trigger a line-break) will add a new line with
height="100px"...

And the winner is..... Andreas!
Indeed setting the line-height made the trick. My block now has a 100
pixel size!
Thanks again for all of you who helped me.

Ok, another go... Try :
<fo:block line-height="100px" display-align="center" ...>
<fo:external-graphic height="25px" />
</fo:block>
Apart from that: Chris is right, the content-width and content-height props
have not been implemented yet.

Daniel,
I tried that too with no success. This brings the following question.
How can I create an empty block with a specified height and width? If I
could create such a block I could embed my image in it.

Can you set the height in the block level itself ?
<fo:block background-color="white" display-align="center" height="100px">
<fo:external-graphic src="..." height="25px" />
</fo:block>

Re: Problem with inserting images [more on problem]
Posted by Patrick JUSSEAU <pa...@openbase.com>.
Hi,
Just to be a little bit more specific about my previous post, I should
clarify what happens when using:
> <fo:block background-color="white" text-align="center">
> <fo:external-graphic content-height="25px" height="100px"
> src="url(image.jpg)"/>
> </fo:block>
When using this code, my image has the correct size (25 pixel in
height) however the viewport height is not 100 pixel (it actually looks
like the viewport height = the image's height. I also tried using
'display-align="center"' on the surrounding fo:block but this does not
work (it even makes things worse since now the image is not align
anymore). What I really want to do is getting a image at its actual
size at the center of a bigger empty block.
Any ideas of how to accomplish this?
Thanks,
Patrick

Still... what would be the pitfall in using 'line-height="100px"' on the
surrounding fo:block?
I guess 'display-align="center"' is being ignored when put on the fo:block
(?) (So he could actually just leave that out).
Are the images automatically centered vertically on the current line? (So
setting the line-height works perfectly in this case, but *could* raise
problems when you need the image aligned at the top of the line? In which
case, Chris' table approach will probably work much better...)
Just some random thoughts...
Cheerz,
Andreas

Check
http://xml.apache.org/fop/fo.html#fo-center-vertical
Not that display-align works only on reference areas (table cells,
fo:block-container and regions). Also, you can only set a height
on table rows and block containers (wont work on ordinary blocks
or table cells).

Hi,
Try using 'display-align="center"' on the surrounding fo:block.
<fo:block background-color="white" text-align="center"
display-align="center">
<fo:external-graphic .../>
</fo:block>
Hope this helps!
