--- Comment #6 from Andreas Beeker <kiwiwi...@apache.org> --- My guess is, you forgot to include the scratchpad and the "provided" jars, which contains the WMF renderer. While trying to describe below, I found out, that the PPTX2PNG argument handling is case-sensitive and so doesn't match the docs, but apart of that it works for me. I think we should also add the "provided" jars to the binary bundle, as this will be less pain for the users and nobody cares nowadays about a increase in the bundle size. - Download and unzip the nightly: https://ci-builds.apache.org/job/POI/job/POI-DSL-1.8/lastSuccessfulBuild/artifact/build/dist/ - Download the "provided" jars and put them in the directory "provided": https://search.maven.org/artifact/org.apache.xmlgraphics/batik-all/1.13/pom https://search.maven.org/artifact/xml-apis/xml-apis-ext/1.3.04/jar https://search.maven.org/artifact/org.apache.xmlgraphics/xmlgraphics-commons/2.4/jar - Execute the java command (Unix-paths needs to be replaced for Windows): java -cp poi-5.0.0-SNAPSHOT.jar:poi-ooxml-5.0.0-SNAPSHOT.jar:poi-ooxml-schemas-5.0.0-SNAPSHOT.jar:poi-scratchpad-5.0.0-SNAPSHOT.jar:lib/*:ooxml-lib/*:provided/* org.apache.poi.xslf.util.PPTX2PNG -format png -fixside long -scale 1000 -charset GBK -outdir . ttt.pptx -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@poi.apache.org For additional commands, e-mail: dev-h...@poi.apache.org
