I do not understand html images very well :D but to insert from Assets use this line

B4X:
re.insertImage("file:///android_asset"&"/txt.png","text")
re is SMMRichEditor

V 2 adds a method (re.Html) to setting or getting HTML
V 0.03 adds TextColor (not tested) requested in post #25

V0.04 added loadCSS(String cssFile) , setBullets() , setNumbers(), focusEditor() , clearFocusEditor()


V0.05 (I have updated library references above :))

It is simple like any other view
B4X:
Dim re as SMMRichEditor
re.Initialize("re")
Activity.Addview(re, 0,0,100%x,100%y)
re.EditorBackgroundColor=colors.Yellow
Text related methods like bold seem to have effect if some text is selected . you might want to add buttons for them.
And for textchanged listener, you add the following Sub
B4X:
Sub re_textchanged(new as string)
Log(new)
End sub

AddToParent adds richeditor to a panel or activity, you can't add views to this richeditor view .
You should replace this line with Activity.AddView(bn,…..)
And add sub bn_click to handle button clicks
For example
B4X:
Sub bn_click
     re.setItalic
End sub

Ok so I don't know anything about wraping code but as it's supported by the original github code I thought it would get wrapped as well.

See the attached in mage it shows they support Header 1, Header 2 etc.

I assume like re.setbold there would be a .setheader1 or similar.
Or do I just not understand.

Also whats ba used for?

Thanks
Tony

Did you try something like this?
B4X:
dim re as SMMRichEditor
re.Initialize("")
re.Heading = 1
Ignore ba it is used by wrapper
