  # Save your screenshot like this:

  #

  #   Screenshot::make("filename", N)

  # or

  #   Screenshot::make("filename", N, "folder/path")

  # 

  # Substitute the filename with the desired name of the image file,

  # replace N with (0 = .bmp, 1 = .jpg and 2 = .png), and "folder/path" with

  # the path to the folder where you want the picture to be saved.

  # If you don't use the third parameter, then the file will be saved in

  # Graphics/Pictures/ inside your game directory.

  # ----------------------------------------------------------------------------

  # Example No.1:

  #   Screenshot::make("MySavedPosition", 2, "C:/")

  #

  # This will create the picture MySavedPosition.png on the C:\ partition of 

  # your hard disk.

  # ----------------------------------------------------------------------------

  # Example No.2:

  #   Screenshot::make("MySavedPosition", 2)

  #

  # This will create the picture MySavedPosition.png in Graphics/Pictures/ 

  # inside your game directory.

  # ----------------------------------------------------------------------------

  # Using this script is simple.

  # To blur an image, use this:

  #

  #   @blured_image = BlurEffect.new(x,y,"folder/filename.ext",blur_factor)

  #

  # I will explain the parameters.

  # x ... the x position of the image on the screen

  # y ... the y position of the image on the screen

  # "folder/filename.ext" ... the format you should use to specify the image

  #                           you want to blur. You can either use a full path

  #                           or relative path. A full path would look like this

  #                           "C:/My Pictures/picture_01.png" and a relative path

  #                           is the one relative to the folder where your game 

  #                           is stored. So a relative path looking like this

  #                           "Graphics/Titles/title.jpg" would be equal 

  #                           to a full path like:

  #                        "C:/My RMXP Games/Project1/Graphics/Titles/title.jpg"

  #                           NOTE: Use JPEG, BMP or PNG files because I'm not

  #                                 sure if RMXP can import other filetypes.

  # blur_factor ... is a number from 1 to 4 which defines the strength of the 

  #                 blur effect. Going past 2 is not recommended because it can

  #                 cause big lag and won't make the blur look much better.

  #                 So I recommend using 1 or 2.

  # ----------------------------------------------------------------------------

  # To free the image from memory, use this:

  #   @blured_image.dispose 

  # if you used the variable @blured_image to store the BlurEffect class object.

  # ----------------------------------------------------------------------------
