[jira] [Commented] (FOP-2972) Incorrectly trim edges of svg figure when using 'auto'

    [ https://issues.apache.org/jira/browse/FOP-2972?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=18077664#comment-18077664 ] 

Joao Goncalves commented on FOP-2972:
-------------------------------------

My solution allows you to set the DPI to whatever value you need, thus working with any SVG. Even if I were to change the default DPI value, it doesn't mean it won't cause issues elsewhere. There are different defaults for DPI values, and for FOP it was set to 72dpi long ago, with the ability to change it to match anyone's needs. The conf can be adapted for each example as well, depending on your needs. 
I'm not trying to convince anyone to change their policies; I'm just saying that, if anyone wants to use FOP, they can change the source-resolution conf to match their needs.

> When using docbook to create a document with a SVG figure, the figure left and right edges are clipped.  The following script demonstrate the problem.  This problem was first reported to the docbook xslt project as issue #212.
