 I'm trying to include images in a PDF document being generated using XSL:FO and XEP 3.7.5. The difficulty I'm having is because I don't know the image format or size before doing the render, so it has to be done automatically in the XSL-FO pass. Images can be anywhere from 100x100px to 1000x1000px. XEP handles the format fine (for the most part), but scaling is unpredictable, even (or particularly) using width="auto" height="auto" content-width="auto" content-height="auto". What I am trying to do is scale down large images to fit within the width of my page, and keep small images their original size (or a reasonable size) - strangely I seem to be having more problems with small images scaling too large rather than vice-versa. This seems to be a case for using the scale-to-fit value (http://xep.xattic.com/xep/testsuite/usecases/image-scale.pdf), but my difficulty is that while I know the absolute width the area I want the image to appear (19cm), I know neither the height (since this should be dependent on the scaled image), and I'm having problems with the image overflowing outside of the block. The pertinent part of the FO for my example is: (full XSL-FO available, it's just very large) <fo:block space-after.optimum="6pt" space-before.optimum="6pt" span="all"> <fo:table width="100%" table-layout="fixed"> <fo:table-column/> <fo:table-body> <fo:table-row keep-with-next="always"> <fo:table-cell> <fo:block id="figure1" span="all" font-size="8.5pt"> <fo:inline font-weight="bold">Figure 1: </fo:inline>Simple EAV schema for a clinical database.</fo:block> </fo:table-cell> </fo:table-row> <fo:table-row keep-with-previous="always"> <fo:table-cell> <fo:block text-align="center" span="all"> <fo:external-graphic src="url(file:y:/jmir/jmir-cocoon/content/v5/v5e27/jmir_v5e27_fig1.jpg)" content-width="auto" content-height="auto" width="auto" height="auto"/> </fo:block> </fo:table-cell> </fo:table-row> <fo:table-row keep-with-previous="always"> <fo:table-cell/> </fo:table-row> </fo:table-body> </fo:table> </fo:block> I have the image and caption in a blind table to keep them together across page-breaks (yes, I know this is ugly but it was the best way I could ensure consistent layout). Should I be using a block-container instead/as well?
