I have a png diagramm (see first image), which has some sort of opacity. I need to remove the text and insert the translated one preferably without hurting this opacity. I tried many things in Photoshop, and the least bad was to just rectangle select and delet the text. But I would like to know the proper solution for removing the text, because when applying non-white background to the edited picture it looks ugly - as show on the second picture.
Any comment and idea is welcome. Thanks
