we are copying chart to new Worksheet in order to take PDF output of chart.
The Chart copies well to the new worksheet but its background colour does not.Since background colour doesn’t copy to new worksheet thus PDF output shows white background.
Here’s the code snippet & excel documents for reference.
private static void chartToPDF() throws Exception {
Workbook workbook = new Workbook(“C:\Aspose Issues\80067\Excel.xlsx”);
WorksheetCollection ws = workbook.getWorksheets();
Chart chart = workbook.getWorksheets().get(0).getCharts().get(“Chart 1”);
ChartShape cshape = chart.getChartObject();
int sheetIndex = ws.add();
com.aspose.cells.Worksheet worksheet = ws.get(sheetIndex);
chart.calculate();
double chartWidthInInches = chart.getChartObject().getWidthInch();
double chartHeightInInches = chart.getChartObject().getHeightInch();
boolean defaultApproach = true;
if (chartWidthInInches > 18 || chartHeightInInches > 5) {
// The approach being followed here is to iterate as many columns as colwidth in pixels & set each column width equal = 1 pixel.
// Similarly for chart height, iterate through as many rows as row height & set each row height = 1 pixel.
// This is being done to fit in large charts that have height & width beyond maximum row/col dimensions & white spaces around
// the chart.
double chartWidthInPixels = chart.getChartObject().getWidth();
double chartHeightInPixels = chart.getChartObject().getHeight();
// Deliberately including one more column because Aspose considers the last column adjacent to chart which leads to white space
// on right of chart
for (int i = 0; i <= chartWidthInPixels; i++) {
worksheet.getCells().setColumnWidthPixel(i, 1);
}
// Deliberately including one more row because Aspose considers the last row adjacent to chart which leads to white space
// below the chart.
for (int i = 0; i <= chartHeightInPixels; i++) {
worksheet.getCells().setRowHeightPixel(i, 1);
}
defaultApproach = false;
} else {
worksheet.getCells().setColumnWidthInch(0, chartWidthInInches);
worksheet.getCells().setRowHeightInch(0, chartHeightInInches);
}
//Setting the name of the newly added worksheet
String transientSheetName = “TransientWorksheet”;
worksheet.setName(transientSheetName);
//Copy the Chart to Second Worksheet
worksheet.getShapes().addCopy(cshape, 0, 0, 0, 0);
//Get the new chart and set its height and width accordingly
com.aspose.cells.Chart chart1 = worksheet.getCharts().get(0);
chart1.getChartObject().setHeightInch(chartHeightInInches);
chart1.getChartObject().setWidthInch(chartWidthInInches);
//Make remaining worksheets invisible so that they are not part of the output pdf
for (int i = 0; i < ws.getCount(); i++) {
String sheetName = ws.get(i).getName();
if(!transientSheetName.equalsIgnoreCase(sheetName)){
ws.get(i).setVisible(false);
}
}
PdfSaveOptions pdfSaveOptions = new PdfSaveOptions();
pdfSaveOptions.setOnePagePerSheet(true);
worksheet.getPageSetup().setTopMargin(0);
worksheet.getPageSetup().setBottomMargin(0);
worksheet.getPageSetup().setRightMargin(0);
worksheet.getPageSetup().setLeftMargin(0);
//Setting Print area to first cell only as the chart is contained in the first cell (A1:A1)
if (defaultApproach) {
worksheet.getPageSetup().setPrintArea(“A1:A1”);
}
// Save the workbook
workbook.save(“D:\out.xlsx”);
// workbook.save(“C:\Aspose Issues\80067\out.pdf”, pdfSaveOptions);
}
Can you suggest options to ensure exact replica of Chart to be copied to the new worksheet.
