HTML Content Is Ignoring Indentation, Line Spacing when Saving from Presentation


a. We added below content in rich text box in slide of Presentation.
image.png (1.2 KB)
b. We converted into html using below code and saved to Database.

 String content = shape.getTextFrame().getParagraphs().exportToHtml(0, shape.getTextFrame().getParagraphs().getCount(), null);

c. Attached the aspose generated html code .Aspose_generated_code.docx (11.9 KB)
d. When generating the report, we retrieved above saved html content from DB and report is generated.
We used below code for this.

IShape iShape = slide.getShapes().addAutoShape(ShapeType.Rectangle, x, y, width, height, false);
shape.getTextFrame().getParagraphs().addFromHtml(StringEscapeUtils.unescapeHtml(content != null ? content : "")); 

e. Report generated like this.

Could you please let us know why below formatting issues are there.
a. Why spacing between Test1 and Test2 is small which is not same as uploaded one.
b. why bullet color blue is not there for Text - Sub bullet
c. Why space is removed between bullet and Text - Sub bullet.

Could you please help us in resolving above issues.

Highlighted the space in yellow color in the attached image.image.png (2.1 KB)

I compared the images and I don’t see that the space has been removed between the bullet and the text. comparing.jpg (20.3 KB). Also, the space can be done differently (whitespaces, first line indentation, tabs, etc.). The remaining text with the same appearance can also be done in different ways. Unfortunately, we need the presentation source file to investigate the cases.

Yes correct, Space is not removed between the bullet and the test.
Could you please look into the case for first 2 issues based on the uploaded the html code.
