4. You could make a different ras through your setting: to produce your ras more clear, please adjust DPI, which is that you can input a greater number in the edit-box of DPI. Here is the reason:

DPI represent resolution in raster images, and RAS is a bitmap image format, DPI is short for dots per inch, which is used in some output like printers or scanners ,so the more your dots per inch is, the more clear your ras is, along with the bigger size and dimension, too.

So here we input 268 in the edit-boxes of DPI.
