XLSX to PDF conversion with Aspose.Cells for Java API in Oracle and Open JDK

Hi,

We are using Aspose.Cells v19.11 for generating outputs (pdf, png, html etc.) of excel charts, tables, ranges and sheets.

Earlier we were using Oracle Java SE 8 and output was rendered fine but now we are using OpenJdk 8 and we have noticed rendering issues in that.

For e.g.: When generating pdf of a particular chart, in case of OpenJdk some of the chart elements like labels, axis values etc. are shifted from their original position.

Please find attached the pdf outputs generated with OracleJdk vs OpenJdk:

Is there any difference in how Aspose works with OpenJdk vs OracleJdk? Is there anything extra that we need to do when using OpenJdk.

Thanks,
Neha

@Neha_Gautam,
There is no such differentiation done by Aspose.Cells and this issue is never reported earlier. We need to investigate it but before that, we would like to know about the complete details of your environment like OS, development IDE and simple runnable console application which can be used to reproduce this issue. You may also share the template file (if any).

Hi,

We are using OpenJdk 8 on Windows Server 2016.

Following code is used to generate the PDF:

Workbook workbook = new Workbook(“test.xlsx”);
WorksheetCollection ws = workbook.getWorksheets();
String worksheetName = “Charts”;
Chart chart = ws.get(worksheetName).getCharts().get(“Chart 1”);
chart.toPdf(“output.pdf”);

Please find attached the source excel to generate the pdf:
