Hi,
extra spaces before and after the image are half leading (above and
below text). They are due to font-size and line-height properties.
If your fo:block doesn't contain any text, you can set them to 0.
Since the line-height property is defaulting to 1.2 (IOW, computed value
is 1.2 * font-size), you only need to explicitly set the font-size to 0
(for the fo:block)

Hello and thank you for reading my post.
When I put a "fo:external-graphic" inside a "fo:block" (cf. the XSL-FO
stylesheet and an image of an excerpt of the resulting PDF document attached
below), I get:
- an extra (red) margin above the image,
- an extra (red) margin below the image (bigger than the previous),
- no extra left or right margins.
What are these margins?
Can they be removed?
Nota:
In the PDF file attached, the image is a GIF image.
The background of the "fo:external-graphic" element is green (rgb(0,255,0)).
The background of the "fo:block" element is red (rgb(255,0,0)).
Thank you and best regards.
