Well, many should think that here is not the place to post this, I thought it some time ago, but come on. I am a programmer, I make websites, and I have not yet participated in any copyright courses. I received a client that has a logo, but it gave me a JPEG logo, in fact the graphic did it this way by default, and they also passed some files in CDR format, PDF. I had to convert this CDR to SVG, so I could edit it in my Inkscape. Now here comes the question. As they designed the logo to have a white background and not to have a transparent background, I decided to edit this logo, now, if I edit this logo, may I be breaking any law? I changed the background of the world that was transparent to white, to be able to give a contrast at the time of inserting in the site, because the water was transparent and the earth with solid color.
Repeating, am I infringing any rights law?
