Set Line Spacing of the Paragraph in a Shape or Textbox with C++

You can set the line space of the paragraph, its space before and space after using the TextParagraph.GetLineSpace(), TextParagraph.GetSpaceBefore() and TextParagraph.GetSpaceAfter() properties of the TextParagraph class.

The following sample code explains the usage of the mentioned properties.

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

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

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

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

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

    // Create a workbook
    Workbook wb;

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

    // Add text box inside the sheet
    ws.GetShapes().AddTextBox(2, 0, 2, 0, 100, 200);

    // Access first shape which is a text box and set its text
    Shape shape = ws.GetShapes().Get(0);
    shape.SetText(u"Sign up for your free phone number.\nCall and text online for free.");

    // Access the first paragraph
    TextParagraph p = shape.GetTextBody().GetTextParagraphs().Get(1);

    // Set the line space
    p.SetLineSpaceSizeType(LineSpaceSizeType::Points);
    p.SetLineSpace(20);

    // Set the space after
    p.SetSpaceAfterSizeType(LineSpaceSizeType::Points);
    p.SetSpaceAfter(10);

    // Set the space before
    p.SetSpaceBeforeSizeType(LineSpaceSizeType::Points);
    p.SetSpaceBefore(10);

    // Save the workbook in xlsx format
    wb.Save(outDir + u"output_out.xlsx", SaveFormat::Xlsx);

    std::cout << "Workbook saved successfully!" << std::endl;

    Aspose::Cells::Cleanup();
}
