Generate Conditional Formatting DataBars Images

Sometimes, you need to generate images of Conditional Formatting DataBars. You can use Aspose.Cells DataBar.ToImage() method to generate these images. This article shows how to generate a DataBar image using Aspose.Cells.

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 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-.NET
//Source directory
string sourceDir = RunExamples.Get_SourceDirectory();

//Output directory
string outputDir = RunExamples.Get_OutputDirectory();

// Create workbook object from source excel file
Workbook workbook = new Workbook(sourceDir + "sampleGenerateDatabarImage.xlsx");

// Access first worksheet
Worksheet worksheet = workbook.Worksheets[0];

// Access the cell which contains conditional formatting databar
Cell cell = worksheet.Cells["C1"];

// Create and get the conditional formatting of the worksheet
int idx = worksheet.ConditionalFormattings.Add();
FormatConditionCollection fcc = worksheet.ConditionalFormattings[idx];
fcc.AddCondition(FormatConditionType.DataBar);
fcc.AddArea(CellArea.CreateCellArea("C1", "C4"));

// Access the conditional formatting databar
DataBar dbar = fcc[0].DataBar;

// Create image or print options
ImageOrPrintOptions opts = new ImageOrPrintOptions();
opts.ImageType = Drawing.ImageType.Png;

// Get the image bytes of the databar
byte[] imgBytes = dbar.ToImage(cell, opts);

// Write image bytes on the disk
File.WriteAllBytes(outputDir + "outputGenerateDatabarImage.png", imgBytes);
