导出带有viewBox属性的SVG图表

默认情况下，当图表导出为SVG格式时，其XML中不包含viewBox属性。但是，Aspose.Cells for Python via .NET提供了ImageOrPrintOptions.svg_fit_to_view_port属性，当设置为true时，将以包含viewBox属性的SVG格式导出图表。

导出带有viewBox属性的SVG图表

以下示例代码将图表导出为带有viewBox属性的SVG格式。

	from aspose.cells import SaveFormat, Workbook
	from aspose.cells.rendering import ImageOrPrintOptions

	# 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 from source file
	workbook = Workbook(dataDir + "SampleChartBook.xlsx")
	# Access first worksheet
	worksheet = workbook.worksheets[0]
	# Access first chart inside the worksheet
	chart = worksheet.charts[0]
	# Set image or print options with SVGFitToViewPort true
	opts = ImageOrPrintOptions()
	opts.save_format = SaveFormat.SVG
	opts.svg_fit_to_view_port = True
	# Save the chart to svg format
	chart.to_image(dataDir + "Image_out.svg", opts)

如果在记事本中打开图表的SVG文件，将会找到类似于这样的viewBox属性。

 <svg xmlns="http://www.w3.org/2000/svg"

     xmlns:xlink="http://www.w3.org/1999/xlink"
 <span class="n">width</span><span class="o">=</span><span class="s">&#34;100%&#34;</span> <span class="n">height</span><span class="o">=</span><span class="s">&#34;100%&#34;</span>
<span class="n">viewBox</span><span class="o">=</span><span class="s">&#34;0 0 480 288&#34;</span><span class="o">&gt;</span></code></pre></div>
