hi, sorry if this is basic, i'm lacking the correct terms and experience.
i have a multicolor png image where i rounded off the corners in paint.net. now i want those corners to be vectorized so you don't see the pixels but a clean line. only the corners should be like that, the rest of the image should be untouched.
i rounded the corners in paint.net by creating a new layer on top of the image, drawing a rectangle with rounded corners on it, centered it, then inverted the selection, switched to the image layer and deleted the selection.
if i try to do this the same way in inkscape, i'm unable to invert the selection. the respective function doesn't seem to do anything, is that because the object i was drawing is still fully rectangular, even when i round its corners?
so basically i'm asking: how can i create clean round corners of a png image in inkscape?
i did also try and just trace the bitmap, but i don't know how the parameters have to be set, it obviously also tries to vectorize the whole image but the results were not good.
thank you and have a nice sunday!
