but I don't think those are the problem. You might try adding a
color to the table cell, and add borders around the cell, block, and
external-graphic to see what is contributing the space.
Only got back to this problem now.... I tried your suggestion, and the
result is at
http://img175.imageshack.us/my.php?image=headerwithcolorle3.png. It just
seems that something is forcing space before (and indeed, a small amount of
space after) the left-hand graphic. (The yellow and blue colors indicate the
left-most and right-most cells in the header table, respectively, while the
left-hand pink indicates the background of the graphic). Nothing in the .fo
file seemed to indicates where this space is from.
Unfortunately, I have _no_ idea how to do this in my custom layer. The
seem to indicate that such a problem might happen, and only describes how to
specify the content of the cells, and not the attributes of the cells
themselves. Any ideas? Is there perhaps a setting in my custom layer which
is causing this problem?
