I had overlooked some char string commands, I’ve now added them and the file from PDFBOX-1019 now renders beautifully.
I will update my patch once JIRA starts working again... -- John On 14 Jan 2014, at 04:48, Tilman Hausherr (JIRA) <j...@apache.org> wrote: > > [ > https://issues.apache.org/jira/browse/PDFBOX-1844?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel > ] > > Tilman Hausherr updated PDFBOX-1844: > ------------------------------------ > > Attachment: redp4581.pdf > > Almost nothing is rendered with this file: > > java.lang.UnsupportedOperationException: Unknown command: dotsection > at > org.apache.fontbox.cff.Type1CharString.handleCommand(Type1CharString.java:265) > at > org.apache.fontbox.cff.Type1CharString.access$000(Type1CharString.java:39) > at > org.apache.fontbox.cff.Type1CharString$1.handleCommand(Type1CharString.java:135) > at > org.apache.fontbox.cff.CharStringHandler.handleSequence(CharStringHandler.java:47) > at > org.apache.fontbox.cff.Type1CharString.render(Type1CharString.java:138) > at > org.apache.fontbox.cff.Type1CharString.getPath(Type1CharString.java:110) > at > org.apache.pdfbox.pdfviewer.font.Type1Glyph2D.<init>(Type1Glyph2D.java:95) > at > org.apache.pdfbox.pdfviewer.font.Type1Glyph2D.<init>(Type1Glyph2D.java:56) > at > org.apache.pdfbox.pdfviewer.PageDrawer.createGlyph2D(PageDrawer.java:523) > at > org.apache.pdfbox.pdfviewer.PageDrawer.processTextPosition(PageDrawer.java:282) > at > org.apache.pdfbox.util.PDFStreamEngine.processEncodedText(PDFStreamEngine.java:485) > at > org.apache.pdfbox.util.operator.ShowTextGlyph.process(ShowTextGlyph.java:62) > at > org.apache.pdfbox.util.PDFStreamEngine.processOperator(PDFStreamEngine.java:529) > at > org.apache.pdfbox.util.PDFStreamEngine.processSubStream(PDFStreamEngine.java:258) > at > org.apache.pdfbox.util.PDFStreamEngine.processSubStream(PDFStreamEngine.java:225) > at > org.apache.pdfbox.util.PDFStreamEngine.processStream(PDFStreamEngine.java:205) > at org.apache.pdfbox.pdfviewer.PageDrawer.drawPage(PageDrawer.java:154) > at org.apache.pdfbox.util.RenderUtil.renderPage(RenderUtil.java:213) > at org.apache.pdfbox.util.RenderUtil.convertToImage(RenderUtil.java:177) > at > org.apache.pdfbox.util.PDFImageWriter.writeImage(PDFImageWriter.java:117) > at pdfboxpageimageextraction.ExtractImages.doPdf(ExtractImages.java:358) > at pdfboxpageimageextraction.ExtractImages.main(ExtractImages.java:80) > > The file I mentioned this morning is also not rendered, I get > > 14.01.2014 13:43:50.195 WARN [main] > org.apache.pdfbox.util.PDFStreamEngine:542 -
