Kopiera former mellan kalkblad med C++

Ibland behöver du kopiera element på ett kalkblad, till exempel bilder, diagram och andra ritobjekt, mellan kalkblad. Aspose.Cells stöder denna funktion. Diagram, bilder och andra objekt kan kopieras med högsta precision.

Den här artikeln ger en detaljerad förståelse för hur man kopierar former mellan arkmallar.

Kopiera en bild från ett ark till ett annat

För att kopiera en bild från ett ark till ett annat, använd metoden Worksheet.Pictures.Add enligt det visade kodexemplet nedan.

#include <iostream>
#include <memory>
#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"PictureCopied_out.xlsx";

    // Create workbook
    Workbook workbook(inputFilePath);

    // Get the Picture from the "Picture" worksheet
    Worksheet pictureSheet = workbook.GetWorksheets().Get(u"Picture");
    Picture picturesource = pictureSheet.GetPictures().Get(0);

    // Get picture data
    Vector<uint8_t> pictureData = picturesource.GetData();

    // Copy the picture to the Result Worksheet
    Worksheet resultSheet = workbook.GetWorksheets().Get(u"Result");
    resultSheet.GetPictures().Add(picturesource.GetUpperLeftRow(), picturesource.GetUpperLeftColumn(), pictureData, picturesource.GetWidthScale(), picturesource.GetHeightScale());

    // Save the Worksheet
    workbook.Save(outputFilePath);

    std::cout << "Picture copied successfully!" << std::endl;

    Aspose::Cells::Cleanup();
}

Kopiera ett diagram från ett ark till ett annat

Följande kod visar användningen av Worksheet.Shapes.AddCopy metoden för att kopiera ett diagram från ett ark till ett annat.

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

using namespace Aspose::Cells;
using namespace Aspose::Cells::Charts;
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"ChartCopied_out.xlsx";

    // Create workbook
    Workbook workbook(inputFilePath);

    // Get the Chart from the "Chart" worksheet
    Worksheet chartSheet = workbook.GetWorksheets().Get(u"Chart");
    Chart chartSource = chartSheet.GetCharts().Get(0);

    // Get the ChartShape object
    ChartShape cshape = chartSource.GetChartObject();

    // Copy the Chart to the "Result" Worksheet
    Worksheet resultSheet = workbook.GetWorksheets().Get(u"Result");
    resultSheet.GetShapes().AddCopy(cshape, 20, 0, 2, 0);

    // Save the Workbook
    workbook.Save(outputFilePath);

    std::cout << "Chart copied successfully!" << std::endl;

    Aspose::Cells::Cleanup();
}

Kopiera kontroller och andra ritobjekt från ett ark till ett annat

För att kopiera kontroller och andra ritobjekt, använd Worksheet.Shapes.AddCopy-metoden som visas i exemplet nedan.

#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"sample2.xlsx";

    // Path of output excel file
    U16String outputFilePath = outDir + u"ControlsCopied_out.xlsx";

    // Create workbook
    Workbook workbook(inputFilePath);

    // Get the Shapes from the "Control" worksheet
    Worksheet controlSheet = workbook.GetWorksheets().Get(u"Control");
    ShapeCollection shapes = controlSheet.GetShapes();

    // Copy the Textbox to the Result Worksheet
    Worksheet resultSheet = workbook.GetWorksheets().Get(u"Result");
    resultSheet.GetShapes().AddCopy(shapes.Get(0), 5, 0, 2, 0);

    // Copy the Oval Shape to the Result Worksheet
    resultSheet.GetShapes().AddCopy(shapes.Get(1), 10, 0, 2, 0);

    // Save the Worksheet
    workbook.Save(outputFilePath);

    std::cout << "Shapes copied successfully!" << std::endl;

    Aspose::Cells::Cleanup();
}
