There are a few things you can do to improve the quality of your images, including anti aliasing. Anti aliasing is a technique used in Photoshop to reduce the appearance of jagged lines and other artifacts in an image. To use anti aliasing, you first need to create a new layer on your image. Then, select the anti aliasing tool from the Tools palette and click on the thumbnail of your desired line or object. The tool will automatically adjust its settings to match those of your layer’s alpha channel. If you want to use anti aliasing on all of your layers, press Ctrl+A (Windows) or Cmd+A (Mac) and then select all of them from the resulting list.
