Copying Paragraph and Portion in PPTX

In order to format presentation text we need to format it on Paragraph and Portion level. Some text properties that can be set on Paragraph level and some - on Portion level. If there is a paragraph or portion in the text that we need to copy to the newly added paragraphs or portions, we need to copy all properties of the respective paragraph or portion to the newly added paragraph or portion.

Copy Paragraph

Paragraph properties can be accessed through ParagraphFormat instance of Paragraph class. We need to copy all the properties of the source paragraph to the target paragraph. In the following example, the CopyParagraph method is shared that takes a paragraph to be copied as an argument. It copies all the properties of the source paragraph to a temporary paragraph and return the same. The target paragraph gets the copied values.

SharedPtr<Paragraph> CopyParagraph(SharedPtr<IParagraph> par)
{
	SharedPtr<Paragraph> para = MakeObject<Paragraph>();

	SharedPtr<IParagraphFormatEffectiveData> paraData = par->get_ParagraphFormat()->GetEffective();

	// use ParagraphFormat to set values
	para->get_ParagraphFormat()->set_Alignment(paraData->get_Alignment());
	para->get_ParagraphFormat()->set_DefaultTabSize(paraData->get_DefaultTabSize());
	para->get_ParagraphFormat()->set_MarginLeft(paraData->get_MarginLeft());
	para->get_ParagraphFormat()->set_MarginRight(paraData->get_MarginRight());
	para->get_ParagraphFormat()->set_FontAlignment(paraData->get_FontAlignment());
	para->get_ParagraphFormat()->set_Indent(paraData->get_Indent());
	para->get_ParagraphFormat()->set_Depth(paraData->get_Depth());
	para->get_ParagraphFormat()->set_SpaceAfter(paraData->get_SpaceAfter());
	para->get_ParagraphFormat()->set_SpaceBefore(paraData->get_SpaceBefore());
	para->get_ParagraphFormat()->set_SpaceWithin(paraData->get_SpaceWithin());

	para->get_ParagraphFormat()->get_Bullet()->set_Type(paraData->get_Bullet()->get_Type());
	para->get_ParagraphFormat()->get_Bullet()->set_Char(paraData->get_Bullet()->get_Char());
	para->get_ParagraphFormat()->get_Bullet()->get_Color()->set_Color(paraData->get_Bullet()->get_Color())  ;
	para->get_ParagraphFormat()->get_Bullet()->set_Height(paraData->get_Bullet()->get_Height()) ;
	para->get_ParagraphFormat()->get_Bullet()->set_Font(paraData->get_Bullet()->get_Font());
	para->get_ParagraphFormat()->get_Bullet()->set_NumberedBulletStyle(paraData->get_Bullet()->get_NumberedBulletStyle());
	para->get_ParagraphFormat()->set_FontAlignment(paraData->get_FontAlignment()) ;

	para->get_ParagraphFormat()->set_RightToLeft(paraData->get_RightToLeft() ? NullableBool::True : NullableBool::False);
	para->get_ParagraphFormat()->set_EastAsianLineBreak(paraData->get_EastAsianLineBreak() ? NullableBool::True : NullableBool::False);
	para->get_ParagraphFormat()->set_HangingPunctuation(paraData->get_HangingPunctuation() ? NullableBool::True : NullableBool::False);

	return para;
}

Copy Portion

Portion properties can be accessed through PortionFormat instance of Portion class. We need to copy all the properties of the source portion to the target portion. In the following example, the CopyPortion method is shared that takes a portion to be copied as an argument. It copies all the properties of the source portion to a temporary portion and return the same. The target portion gets the copied values.

SharedPtr<Portion> CopyPortion(SharedPtr<IPortion> por)
{
	SharedPtr<Portion> temp = MakeObject<Portion>();

	SharedPtr<IPortionFormatEffectiveData> portData = por->get_PortionFormat()->GetEffective();

	// use PortionFormat to set values
	temp->get_PortionFormat()->set_AlternativeLanguageId(portData->get_AlternativeLanguageId());
	temp->get_PortionFormat()->set_BookmarkId(portData->get_BookmarkId()) ;
	temp->get_PortionFormat()->set_Escapement(portData->get_Escapement()) ;
	temp->get_PortionFormat()->get_FillFormat()->set_FillType(por->get_PortionFormat()->get_FillFormat()->get_FillType());
	temp->get_PortionFormat()->get_FillFormat()->get_SolidFillColor()->set_Color(portData->get_FillFormat()->get_SolidFillColor()) ;

	temp->get_PortionFormat()->set_FontBold(portData->get_FontBold() ? NullableBool::True : NullableBool::False);
	temp->get_PortionFormat()->set_FontHeight(portData->get_FontHeight());
	temp->get_PortionFormat()->set_FontItalic(portData->get_FontItalic() ? NullableBool::True : NullableBool::False);
	temp->get_PortionFormat()->set_FontUnderline(portData->get_FontUnderline());
	temp->get_PortionFormat()->get_UnderlineFillFormat()->set_FillType(portData->get_UnderlineFillFormat()->get_FillType());
	temp->get_PortionFormat()->get_UnderlineFillFormat()->get_SolidFillColor()->set_Color(portData->get_UnderlineFillFormat()->get_SolidFillColor());
	temp->get_PortionFormat()->set_IsHardUnderlineFill(portData->get_IsHardUnderlineFill() ? NullableBool::True : NullableBool::False);
	temp->get_PortionFormat()->set_IsHardUnderlineLine(portData->get_IsHardUnderlineLine() ? NullableBool::True : NullableBool::False);

	temp->get_PortionFormat()->set_KerningMinimalSize(portData->get_KerningMinimalSize()) ;
	temp->get_PortionFormat()->set_Kumimoji(portData->get_Kumimoji() ? NullableBool::True : NullableBool::False);
	temp->get_PortionFormat()->set_LanguageId(portData->get_LanguageId());

	temp->get_PortionFormat()->set_LatinFont(portData->get_LatinFont()) ;
	temp->get_PortionFormat()->set_EastAsianFont(portData->get_EastAsianFont());
	temp->get_PortionFormat()->set_ComplexScriptFont(portData->get_ComplexScriptFont());
	temp->get_PortionFormat()->set_SymbolFont(portData->get_SymbolFont());

	temp->get_PortionFormat()->set_TextCapType(portData->get_TextCapType());
	temp->get_PortionFormat()->set_Spacing(portData->get_Spacing());
	temp->get_PortionFormat()->set_StrikethroughType(portData->get_StrikethroughType());
	temp->get_PortionFormat()->set_ProofDisabled(portData->get_ProofDisabled() ? NullableBool::True : NullableBool::False);
	temp->get_PortionFormat()->set_NormaliseHeight(portData->get_NormaliseHeight() ? NullableBool::True : NullableBool::False);
	temp->get_PortionFormat()->set_HyperlinkMouseOver(portData->get_HyperlinkMouseOver());
	temp->get_PortionFormat()->set_HyperlinkClick(por->get_PortionFormat()->get_HyperlinkClick());
	temp->get_PortionFormat()->get_HighlightColor()->set_Color(portData->get_HighlightColor());

	return temp;
