Generate Conditional Formatting DataBars Images

Contents
[ ]

Example

The following sample code generates the DataBar image of cell C1. First, it accesses the format condition object of the cell, and then from that object, it accesses the DataBar object and uses its DataBar.toImage() method to generate the image of the cell. Finally, it saves the image on disk.

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java
String sourceDir = Utils.Get_SourceDirectory();
String outputDir = Utils.Get_OutputDirectory();
Workbook workbook = new Workbook(sourceDir + "sampleGenerateDatabarImage.xlsx");
// Access first worksheet
Worksheet worksheet = workbook.getWorksheets().get(0);
// Access the cell which contains conditional formatting databar
Cell cell = worksheet.getCells().get("C1");
// Create and get the conditional formatting of the worksheet
int idx = worksheet.getConditionalFormattings().add();
FormatConditionCollection fcc = worksheet.getConditionalFormattings().get(idx);
fcc.addCondition(FormatConditionType.DATA_BAR);
fcc.addArea(CellArea.createCellArea("C1", "C4"));
// Access the conditional formatting databar
DataBar dbar = fcc.get(0).getDataBar();
// Create image or print options
ImageOrPrintOptions opts = new ImageOrPrintOptions();
opts.setImageType(ImageType.PNG);
// Get the image bytes of the databar
byte[] imgBytes = dbar.toImage(cell, opts);
// Write image bytes on the disk
FileOutputStream out = new FileOutputStream(outputDir + "databar.png");
out.write(imgBytes);
out.close();
// save workbook with databars
workbook.save(outputDir + "databar.xlsx");
