    [ https://issues.apache.org/jira/browse/XGC-140?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17812316#comment-17812316 ] 

Simon Steiner commented on XGC-140:
-----------------------------------

You can try disabling raw png in the fop.xconf:
<image-loading>
<penalty value="10000" class="org.apache.xmlgraphics.image.loader.impl.PreloaderRawPNG"/>
<penalty value="10000" class="org.apache.xmlgraphics.image.loader.impl.ImageLoaderRawPNG"/>
</image-loading>

>  
> h2. Steps to reproduce
>  # Have the following installed:
>  ## FOP 2.9
>  ## Batik 1.17 (which uses/depends on xmlgraphics-commons 2.9)
>  # Try to process {{<fo:external-graphic src="file:\\\D:\interlaced_image.png"/>}} (the image has been attached to the issue)
> h2. Expected behavior
> A correct PDF is generated
> h2. Actual behavior
> The above error message is generated
> h2. Additional notes
> FOP 2.9 with Batik 1.16 works (probably because it uses/depends on xmlgraphics-commons 2.7), but Batik 1.16 is vulnerable.
