Pascal you have been really helpful.
For the completeness of this thread I paste the XSLT code that solves my
problem:
<fo:external-graphic src="{$imageLink}" border="solid 3px"
border-color="{$assocBorderColor}"
inline-progression-dimension.maximum="85mm"
block-progression-dimension.maximum="85mm"
content-height="scale-to-fit"/>
This way the border goes around the image without leaving any white space.
Thank you a lot.

Pascal,
the information that you provide are valuable.
Can you propose any open source library in order to manipulate the
quality/resolution of the image?
I tried the imgscalr, getScaledInstance(), Thumbnailator and some more
but they do not provide em exactly what I want.
I haven't tried yet JMajick.
Thanks again.

Quality loss may depend on PDF viewer settings and capabilities
(anti-aliasing, zoom factor, etc.)
Also, the result can seem better if you first resample your image before
using in PDF, to get the best fit on screen reading, but can become
worse on printing.
Depending on what usages your PDF are for (reading on screen, Laser
printing, Offset printing, low weight downloading, etc.)
There is no perfect solution there.
For example, we (my compagny) produce images with different
quality/resolution for identified purposes, and generate as many PDF files.
The only constant over various resampled images is the real size:
for instance, a square image (1"x1") will give:
96x96, rez 1/96" for screen reading;
300x300, rez 1/300" for Laser printing;
120x120, rez 1/120" for Dowload _and_print;
etc.

Hi Pascal,
yes indeed this was one of my problems.
I will test it to see the results.
In case I will still have to manipulate the image outside of the FOP do
you have any solution to propose regarding:
How to change the print size of the image (like gimp) in order not to
loose image quality and at the same time to show it smaller inside the PDF.
Thank you.

Hi,
I guess that by "the result is problematic with very tall images" you
mean that image can overflow the page when h/w ratio is too high.
If this is the case, you can use "max-height" XSL-FO equivalent:
<fo:external-graphic src="{$imageUrl}"
block-progression-dimension.optimum="$my_minimal_height"
block-progression-dimension.maximum="$my_maximal_height"
content-height="scale-to-fit"/>

Dear FOP users,
I want to change an image's print size in order to add it inside a PDF.
I want to do this in order not to loose any quality.
The image must look smaller inside the PDF but the quality should be the
same with the original image.
I know that I could do something like this in my XSLT
(content-width="scale-to-fit"):
<fo:external-graphic src="url('{$imageLink}')"
content-width="scale-to-fit" border="solid 0.1pt" width="90mm" />
<fo:block space-before="{$space}"/>
(<xsl:value-of select="$title"/>)
<fo:block/>
<xsl:value-of select="$description"/>
</fo:block>
but the result is problematic with very tall images.
Thus I thought that I should manipulate the image before passing it to FOP.
I used GIMP and I saw that if I change the print size of the image FOP
uses this size and the quality of the image is very good.
Anybody knows how to solve this problem?
Thank you in advance.
