Thanks for your answer. If i have understand this, the lib can create and write the rtf-objects. I need to open, display, show, edit and write the result of existing rtf-files or rtf-blobs from an existent database. It is not useful to convert it to html, it should be the real rtf-format. the source of it is a desktop-application wiht rtf-controls in it to create rtf-data. I think a important problem is that also images are emdedded.
i habe not found any useful rtf-control to implement ist as usercontrol in b4a. I think rtf is an olf interoprable format, most of our customers (radiology, medicine) use this format, i cannot convert it, the result must be readable for the existing desktop applications.....
