Copyright owners hold control over any modification of their works. If you revise, adapt, or transform a work that someone else owns, you have created a "derivative work." If an ordinary observer would say that your version is basically the same as the original, then you must obtain written permission from the copyright owner to use the derivative work you created. Merely changing the font or orientation or making other slight changes is not enough.
However, facts cannot be copyrighted. So, if you extract data from a copyrighted figure, table, or text, and you substantially change the format so that an ordinary observer would say that your version is significantly different from the original, you do not have to seek permission. For example, if you add editorial revisions, annotations, elaborations, or other modifications that display sufficient originality, then you do not need to seek permission.
