Working with the Shadow Effect of Shape or Chart with C++

Possible Usage Scenarios

Aspose.Cells provides the GetShadowEffect() method along with the ShadowEffect class to work with the shadow effect of shapes or charts. The ShadowEffect class contains the following properties which can be set to achieve different results as per application requirements.

• GetAngle()
• GetBlur()
• GetColor()
• GetDistance()
• GetPresetType()
• GetSize()
• GetTransparency()

Working with the Shadow Effect of Shape or Chart

The following sample code loads the source Excel file, accesses the first shape in the first worksheet, sets the sub‑properties of the GetShadowEffect() property, and then saves the workbook to the output Excel file.

#include <iostream>
#include "Aspose.Cells.h"

using namespace Aspose::Cells;
using namespace Aspose::Cells::Drawing;

int main()
{
    Aspose::Cells::Startup();

    // Source directory path
    U16String srcDir(u"..\\Data\\01_SourceDirectory\\");

    // Output directory path
    U16String outDir(u"..\\Data\\02_OutputDirectory\\");

    // Path of input Excel file
    U16String inputFilePath = srcDir + u"sample.xlsx";

    // Path of output Excel file
    U16String outputFilePath = outDir + u"output_out.xlsx";

    // Load your source Excel file
    Workbook wb(inputFilePath);

    // Access the first worksheet
    Worksheet ws = wb.GetWorksheets().Get(0);

    // Access the first shape
    Shape sh = ws.GetShapes().Get(0);

    // Set the shadow effect of the shape: set its Angle, Blur, Distance, and Transparency properties
    ShadowEffect se = sh.GetShadowEffect();
    se.SetAngle(150);
    se.SetBlur(4);
    se.SetDistance(45);
    se.SetTransparency(0.3);

    // Save the workbook in xlsx format
    wb.Save(outputFilePath);

    std::cout << "Shadow effect applied successfully!" << std::endl;

    Aspose::Cells::Cleanup();
