Eliminating block's padding around an external-graphic
Hi, I'm placing images with different heights into table rows. The highest image within a row should define the height of the row. All other images are centered vertically. The table-cells get a background-color, so when an image's height is less than the height of the highest image of its row, one should see the background-color above and below that image. But I've noticed the background-color above and below the highest image, too. Especially in rows with just images of definitely same size (where the background-color never should appear) I can see a padding to the top and a larger padding to the bottom. So I made a simple test without a table: The result is: http://apache-fop.1065347.n5.nabble.com/file/n39020/screen.png Altough *padding*, *margin* (and some other properties I tried to fix this) are set to *0* for the *block* and the *external-graphic* there is still some space above and below the image. The result I expected would be something like this: http://apache-fop.1065347.n5.nabble.com/file/n39020/nominal.png What properties can I add to eliminate that (cyan) space above and below the image?

RE: Eliminating block's padding around an external-graphic
Hi Christoph, If I'm understanding correctly, this issue is caused by FOP taking into consideration line spacing even when there's no text. Try setting the parent block to have font-size=0 and that should resolve the problem. If that doesn't resolve it or do what you want it to, it might be best to post a sample FO file to show the problem and I'll take another look.

Re: Memory usage and page numbering...
Hi, I noticed memory leak issue in font complex-scripts features with trunk code. Not seen any memory issues with page numbers/totals. I tested my code on Mac 10.7 and CentOS 6.4 with visualvm profiler. Thank you, Mahesh On Fri, Aug 9, 2013 at 12:20 AM, Bernard Giannetti thebernmeis...@hotmail.com wrote: Hi, I have a Java desktop application, using embedded FOP to create PDFs from a data XML file and an XSLT file. I wanted to see how much memory is being used, given the point about memory usage, page numbers and page totals ( http://xmlgraphics.apache.org/fop/1.1/running.html#memory). My PDF reports have a page N of TOTAL at the bottom right of each page and I wanted to see the memory usage and compare to no page numbers and just page numbers without totals. I also used the two variations for page number totals (XSL 1.0 and XSL 1.1). To work out the memory usage I computed the difference when calling Runtime.getRuntime().freeMemory() at the start and end of the render process. I ran each render variation 5 times from a shell script and each render kicked off a separate JVM to avoid any caching. Regardless of whether I had page numbers or not, and page totals or not, it seemed the result is that there is no difference between having page numbers/totals or not. Sometimes the memory usage was 50 MB and sometimes 200 MB. I then used the sample code and data files from embedded FOP, http://svn.apache.org/viewvc/xmlgraphics/fop/tags/fop-1_1/examples/embedding/. I modified the data XML file to contain lots of entries, giving a data file size of about 1 MB. I also modified the XLST file to include pages numbers and then also page totals. Again, I noticed no difference in memory usage. Given the varying values for memory usage I'm seeing, I assume my quick and dirty method is inadequate. I expected variation, but mostly to see far less memory usage when no page totals were used, but that's not the case. Has anyone seen similar results? Does using page totals really use THAT much more memory compared to not using page totals? Thanks in advance, Bernard.
