I am a beginner for photoshop. There are something I still can't do well. first of all, When I use Select>Modify>Border... It creates border corner is round. I want it straight. I couldn't find where i can change the settings. Secondly, I use photoshop to create rectangular. After that, I rotated the rectangular, and then the sides look not straight. It is not nice. Who can tell me how to solve the problems. Thanks!!!
