Hello Cindy,
In cases when image is taller than available space and vertical
scaling is performed you get an overflow. The reason is simple:
height="100%" means "as high as parent reference area content
rectangle", however fo:external-graphic is an inline-level element and
thus preceded and followed by empty-space known as half-leading. As a
result the whole content is higher then available space and XEP drops
overflowed image. In order to fix this problem you can simply set
line-height="0pt" on the block that enclose image.
Best regards,

CCCS> Hi all,
CCCS> I have another question regarding image scaling. I am trying to scale and place an image into one page. So I defined FO like following:
CCCS> <fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">
CCCS> <fo:layout-master-set>
CCCS> <fo:simple-page-master page-width="110mm" page-height="150mm" master-name="sample">
CCCS> <fo:region-body border="solid" region-name="xsl-region-body"/>
CCCS> </fo:simple-page-master>
CCCS> </fo:layout-master-set>
CCCS> <fo:page-sequence master-reference="sample">
CCCS> <fo:flow flow-name="xsl-region-body">
CCCS> <fo:block>
CCCS> <fo:external-graphic src="url(Images/spots.jpg)" display-align="center" text-align="center"
CCCS> content-width="scale-to-fit" width="100%" content-height="scale-to-fit" height="100%"/>
CCCS> </fo:block>
CCCS> </fo:flow>
CCCS> </fo:page-sequence>
CCCS> </fo:root>
CCCS> It worked fine as I expected. But one thing is that if I make the page width bigger than page height, I got an error stating:
CCCS> [warning] no space for an element, trying to recover
CCCS> Following is the two cases that will both cause the error:
CCCS> <fo:simple-page-master page-width="110mm" page-height="150mm" master-name="sample" reference-orientation="90">
CCCS> <fo:simple-page-master page-width="150mm" page-height="110mm" master-name="sample">
CCCS> The image I am using is the one comes with the XEP sample code.
CCCS> How could I avoid the error?
CCCS> Thanks,
CCCS> Cindy Chen
