Problem with my report size

[louis.gely]

Hi!

 

I'm generating pdf reports with charts using JFreeChart 1.0.0 and JasperReports 1.2.1.

 

Before the application was generating the same reports using JasperReports 0.6 and JFreeChart 0.6.

 

Ancient report's size = 200ko

New report's size = 3Mo

 

Does someone have an explanation for this.

 

I tried every thing but nothing change...

 

What is the format for the charts' images? Is it different than in the old version of JasperReports?

 

For the information I'm generating my charts with scriptlet. An I would like to know if there was signigicant modification that could produce this huge size of report.

 

Thank you in advance.

I read in the forum, that between JasperReports 0.6.8 and JasperReports 1.2.0 the pdf report that are generated are 3 times bigger (with image or charts). In my case, it's more than 10 time bigger, between 0.6.2 and 1.2.1 reports.

 

Weird?

No idea? Please :(

 

Thank you again!

[lucianc]

Could you post a (simple) sample to replicate this? Also, that are the iText versions you're using?

I am using now iText 1.3.1 and before it was iText 1.0.1.

 

Here some sample of the scriptlet for the pie chart :

 

Code:

public void afterDetailEval() throws JRScriptletException {
        super.afterDetailEval();
        PieDataset dataset = null;
        try {
            dataset = (PieDataset) JFreeDataSetFactory.getInstance().getDataSet(
                JFreeDataSetFactory.DS_BUILDER_ENCOURS_ECHEANCE, this.getReportParameters());
        } catch (ExceptionTechnique e) {
            // TODO Auto-generated catch block
            throw new JRScriptletException("Impossible de construire le DataSet pour l chart ["
            + JFreeDataSetFactory.DS_BUILDER_ENCOURS_ECHEANCE + "] Titre" + "["
            + EncoursParEcheanceChartReport.REPORT_DEFAULT_TITLE+ "]", e);
        }
        JFreeChart chart = ChartFactory.createPieChart3D(
            EncoursParEcheanceChartReport.REPORT_DEFAULT_TITLE, dataset, true, true, false);
        //Customization
        ChartsUtils.configureStandard3DPiePlot((PiePlot3D) chart.getPlot());
        ChartsUtils.configureStandardLegend((LegendTitle)chart.getLegend());
        this.setVariableValue(EncoursParEcheanceChartReport.VAR_CHART_ENCOURS, new JCommonDrawableRenderer(chart));
    }

 

The scriptlet for the timesseries chart :

 

Code:

[code] public void afterDetailEval() throws JRScriptletException { String libelleFonds = (String) this.getParameterValue(HistoVLParFondsReport.PRM_FONDS_NAME); String fondsID = (String) this.getParameterValue(HistoVLParFondsReport.PRM_FONDS_ID); if (fondsID != null) { //Edition chart VL sur la période donnée TimeSeriesCollection chartVLSeries = null; Map reportParameters = getReportParameters(); try { chartVLSeries = (TimeSeriesCollection) JFreeDataSetFactory.getInstance().getDataSet( JFreeDataSetFactory.DS_BUILDER_HISTO_VL_PAR_FONDS, reportParameters); } catch (ExceptionTechnique e) { StringBuffer errorSgb = new StringBuffer(); String sep = System.getProperty("line.separator"«»); String indent = "t"; errorSgb.append("HistoVLParFondsScriptlet.beforeReportInit :: "«»).append(sep).append(indent).append( "Erreur en création de la Série histo des VL [" + e.getClass() + "]"«»).append(sep).append(indent) .append("[" + e.getMessage() + "]"«»).append(sep).append(indent).append("FondsID[" + fondsID + "]"«») .append(sep).append(indent).append("FondsNom[" + libelleFonds + "]"«»).append(sep).append(indent).append( "Une série vierge va être utilisée."«»); LOG.error(errorSgb.toString(), e); chartVLSeries = new TimeSeriesCollection(new TimeSeries(fondsID)); } TimeSeries vlSeries = chartVLSeries.getSeries(fondsID); vlSeries.setKey(libelleFonds); //vlSeries.setName(libelleFonds); double pourcent = 0; if (vlSeries.getItemCount() > 0) { pourcent = (vlSeries.getValue(vlSeries.getItemCount() - 1).doubleValue() - vlSeries.getValue(0) .doubleValue()) / Math.max(vlSeries.getValue(0).doubleValue(), 0.001); } JFreeChart chartVLSeriesAnnee = ChartFactory.createTimeSeriesChart( libelleFonds + " - " + (String) reportParameters.get(ReportsPeriodiqueConstants.PRM_PERIODE_LABEL), "", "en u20AC", chartVLSeries, false, false, false); ChartsUtils.configureStandardXYPlot((XYPlot)chartVLSeriesAnnee.getPlot()); ChartsUtils.configureTitle(chartVLSeriesAnnee.getTitle()); this.setVariableValue(HistoVLParFondsReport.VAR_CHART_VL, new JCommonDrawableRenderer(chartVLSeriesAnnee)); this.setVariableValue(HistoVLParFondsReport.VAR_POURCENT_EVOL, new Double(pourcent)); }

Thank you, and if you need more code I'll reply fast.

 

Thanks again.

[lucianc]

The increase in the PDF size seems to be related to chart texts/fonts. At some point between JR 0.6.6 and JR 0.6.7, a PdfContentByte.createGraphics call, used to retrieve Graphics2D instances on which SVG images were to be rendered, was replaced by PdfContentByte.createGraphicsShapes and this resulted in chart texts being rendered as shapes.

 

Not sure at this moment whether there are other changes (after JR 0.6.7) that affect this or what could be done to fix it.

Lucian

[louis.gely]

Thank you for your explanation. I'll try to generate my charts without font for a time.

 

If you find a solution or path, I will be very happy.

 

Thank you again for your concern.

 

Louis

[lucianc]

Temporarily, you could also revert the change by getting the JR sources and changing in JRPdfExporter.java this line

Code:

Graphics2D g = template.createGraphicsShapes(availableImageWidth, availableImageHeight);

to

Code:

[code]DefaultFontMapper mapper = new DefaultFontMapper(); Graphics2D g = template.createGraphics(availableImageWidth, availableImageHeight, mapper);

Thank you for your help, with that change I lost almost 80% of my report size... It will be temporarily appreciated by my file system.

 

I keep in touch with you.

 

Thanks again.

[louis.gely]

Hello again,

 

Another question : Do you know if this problem will be solve in a futur version of JasperReports?

 

Thank you again and in advance for your responce.

 

Regards,

 

Louis Gely

[lucianc]

I couldn't tell at the moment, we need to investigate this more. I think it would be better to post a bug (here) so that we can track this properly.

 

Regards,

Lucian

[louis.gely]

It's done, I reported the bug. I don't know if I did it the right way...

 

Thanks Again my boss is satisfied with the patch :)

 

Regards,

 

Louis

[lucianc]

The bug is fine.

 

Happy I was able to help.

 

 

Regards,

Lucian

[louis.gely]

I patch my application with succes. But I'm wondering if there is an application which can allow me to reduce my old (and very large) reports.

 

I tried to zip them but nothing change.

 

Does someone have in mind a possible solution?

 

Thank you in advance.

 

Louis

[louis.gely]

Any idea?

[louis.gely]

Any help?

 

Thanks again

[louis.gely]

Again no idea?

 

Thanks

[louis.gely]

Still nothing?

 

Thank you?
