Hi there,
I am creating a slide using Aspose.Slides.dll of version 15.4.0.0. In nested unordered listing, I am having an UL within an UL. The problem is, font size of contents of Inner UL does not come same as the outer UL content,
Current output:
•Capita was formed in 1984 within the
Chartered Institute of Public Finance and Accountancy.
•The company is headquartered in London,
UK, and is listed on the London Stock Exchange.
•It provides customer and business process
management services to organisations
in industries such as healthcare, property services, general insurance,
investor and banking, services, integrated services, IT services and
consulting.
•The company’s business segments are as
follows:
•Health & Wellbeing
•IT Services
•Justice & Secure Services
•Professional Services
•Professional Services
•Professional Services
•Professional Services
•Professional Services
Desired Output:
Font size of contents of nested UL/ Inner UL should be same as Outer UL content.
Please help. Please see below my code, Please find attached template file and generated pptx as well.
Code:
CreateUnorderedListing();
protected void CreateUnorderedListing()
{
string template = ConfigurationManager.AppSettings["TemplateFilePath"];
Presentation pres = new Presentation(MapPath(".") + "\\Templates\\PPTXTemplate.pptx");
ISlide sld = pres.Slides[pres.Slides.Count - 1];
IAutoShape iShapeBody = null;
//Iterate through shapes to find the placeholder
foreach (IShape shp in sld.Shapes)
{
if (shp.Placeholder != null)
{
if (shp is IAutoShape )
{
iShapeBody = (IAutoShape)shp;
}
}
}
