Why does firstLineIndent have to be -20 ?

[Stephan Weber]

Hello,

i´m currently implementing a PPTX with .NET Core and Syncfusion Presentation 17.2.0.35. 

The PPTX is supposed to create a list with bullets. This list can have multiple levels, which the paragraph IndentLevelNumber should support. 

But here comes the problem: 

If I do not set the FirstLineIndent to -20, the text of the paragraph will continue to write under the bullet after a line break... why? 

I need to edit the Indent of a Bullet but it seems like FirstLineIndent has to be set to -20 and has no other effect. 

If it is set to -20 the text writes under each other as expected after a line break. 

I checked this document of yours https://help.syncfusion.com/file-formats/presentation/working-with-list 

And it also says I have to set it to -20. 

Regards.

Hi Steffen,

Thank you for contacting Syncfusion support.

Syncfusion Presentation library provided a support to modify the indent of a paragraph similar to Microsoft PowerPoint. Please find the below API details, 

Microsoft PowerPoint Screenshot	Syncfusion API	Syncfusion API Details
	FirstLineIndent	FirstLineIndent property is used to set a special indent of a paragraph such as (First line indent and Hanging Indent). This property works similar to highlighted property in a Microsoft PowerPoint screenshot.  FirstLineIndent property is act as First line indent if you set a positive value and it act as Hanging indent if you set an negative values.
	LeftIndent	LeftIndent property is used to set a Before text indent of a paragraph. This property works similar to highlighted property in a Microsoft PowerPoint screenshot.

 

If I do not set the FirstLineIndent to -20, the text of the paragraph will continue to write under the bullet after a line break... why?

As per the Microsoft PowerPoint behavior, If we set an hanging indent 20 (FirstLineIndent = -20) to the bullet contained paragraph with some left indent values, It moves a bullet character alone in left side from a left indent value. (Paragraph remains its position). 

If we set first line indent 20 (FirstLineIndent = 20) to the bullet contained paragraph with some left indent values, It moves a first line of paragraph alone in right side from a left indent value. (Bullet character remains its position).

I need to edit the Indent of a Bullet, but it seems like FirstLineIndent has to be set to -20 and has no other effect. If it is set to -20 the text writes under each other as expected after a line break.
You can able to customize the indent of an bullet from a paragraph by modifying the values of our FirstLineIndent and LeftIndent properties similar to Microsoft PowerPoint.

Please let us know if you need any further assistances in this.
