XSL Formatter Q&A

Q.	When I specified a image as follows, it created a thin white strip on the top of the image. How should I specify it? <fo:block-container position="fixed" top="0" left="0" height="AAApx" width="BBBpx" background-color="white"> <fo:block> <fo:external-graphic src="test.jpg" scaling="non-uniform" content-height="AAApx" content-width="BBBpx" /> </fo:block> </fo:block-container> [No.2005052701]
A.	Please specify `line-height="1"` and `font-size="0pt"` for `fo:block`. So the example becomes: <fo:block-container position="fixed" top="0" left="0" height="AAApx" width="BBBpx" background-color="white"> <fo:block line-height="1" font-size="0pt"> <fo:external-graphic ... Because `fo:external-graphic` is an inline element, it makes line area. The default height of line area is 1.2em, so you should specify `line-height="1"` for the block. However, even though `line-height="1"` is specified, a graphic is placed on top of a baseline and there remains a space under the baseline as a result. In order to avoid this, you should specify `font-size="0pt"`, too.

<fo:block-container position="fixed" top="0" left="0" 
  height="AAApx" width="BBBpx"  background-color="white">

Please specify line-height="1" and font-size="0pt" for fo:block. So the example becomes:

<fo:block-container position="fixed" top="0" left="0" 
  height="AAApx" width="BBBpx"  background-color="white">
  <fo:block line-height="1" font-size="0pt">
    <fo:external-graphic ...

Because fo:external-graphic is an inline element, it makes line area. The default height of line area is 1.2em, so you should specify line-height="1" for the block.

However, even though line-height="1" is specified, a graphic is placed on top of a baseline and there remains a space under the baseline as a result. In order to avoid this, you should specify font-size="0pt", too.
