[jira] [Commented] (FOP-2890) fo:change-bar problem with AT format

["Jan Tošovský (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FOP-2890?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16985216#comment-16985216 ] 

Jan Tošovský commented on FOP-2890:
-----------------------------------

I can reproduce. I tend to say AT file is generated properly, but it is then rendered incorrectly. The problematic is bpd value of inlineblock element. It represents the height of change-bar. It should not affect the subsequent text elements, but in reality all the text content is shifted vertically.
{code:xml}
<inlineblock ipd="0" bpd="15000" bpda="15000" bap="1000 1000 0 0"
             border-start="(solid,#000000,1000)" border-end="(solid,#000000,1000)"
             left-offset="-22677" top-offset="-3900"/>
<text offset="0" baseline="8616" ipd="122712" bpd="11100" ipda="122712" bpda="11100" bap="0 0 0 0" color="#000000">
{code}
Btw, inlineblock element was incorporated together with the change-bar support to cover change-bar flexibility. It seems there are edge cases which needs further polishing.

I can imagine to implement condition like 'if preceding node is inlineblock element, its bpd value is somehow ignored'.
