Reusing Style Objects

Reusing style objects can save memory and make a program faster.

To apply some formatting to a large range of cells in a worksheet:

1. Create a style object.
2. Specify the attributes.
3. Apply the style to the cells in the range.

from aspose.cells import Workbook
from aspose.pydrawing import Color

#  For complete examples and data files, please go to https:# github.com/aspose-cells/Aspose.Cells-for-.NET
#  The path to the documents directory.
dataDir = RunExamples.GetDataDir(".")
#  Create workbook object
workbook = Workbook()
#  Access the first worksheet
worksheet = workbook.worksheets[0]
#  Access cells
cell1 = worksheet.cells.get("A1")
cell2 = worksheet.cells.get("B1")
#  Set the styles of both cells to Times New Roman
styleObject = workbook.create_style()
styleObject.font.color = Color.red
styleObject.font.name = "Times New Roman"
cell1.set_style(styleObject)
cell2.set_style(styleObject)
#  Put the values inside the cell
cell1.put_value("Hello World!")
cell2.put_value("Hello World!!")
#  Save to Pdf without setting PdfSaveOptions.IsFontSubstitutionCharGranularity
workbook.save(dataDir + "SampleOutput_out.xlsx")

Because the Cell.get_style/Cell.set_style approach uses a lot less memory, and is efficient, the older Cell.Style property which consumed a lot of unnecessary memory, was removed with the release of Aspose.Cells 7.1.0.
