Hİ.. I have installed fedora and then pinta, but I can't resize white new canvas manually , It is very helpful option because I sometimes make motivational poster or put two pictures on one canvas, I could do it easily in ms paint holding one of the corner and drag where I want,

Any helps are welcomed, thank you very much.. or any other software you can suggest that I can do what I want easily

(I could do it on kolourpaint just like on ms paint but my DE is mate and I dont want to install tons of kde depencies installing just one software, thank you very much
