is there a boss who knows where there is a rich text editor similar to Wechat"s background editing graphics and text, open source. In doing a demand, customers edit pictures and text in the background, and then show in the foreground, I use Baidu"s ueditor to do an editor, customers are used to editing articles with Wechat"s background graphics and text, want to adjust line spacing, kerning, picture size, etc., Baidu"s rich text editor does not adjust line spacing, kerning function. Do you know any rich text editor that can upload and resize pictures and adjust line spacing and kerning at the same time?
