1. An information processing apparatus comprising:
- one or more computer processors; and
a non-transitory memory which stores instructions, which, when executed by the one or more computer processors, cause the one or more computer processors todetect a contact position of an operating tool which has contacted a screen;
detect a contact area size of the operating tool which has contacted the screen;
detect a pressure of the operating tool pressing the screen; and
set, according to the contact area size of the operating tool on an object displayed on the screen and the pressure of the operating tool pressing the object, an amount of ink assumed to have been attached to the operating tool, whereinthe object is provided for each colour,the processor is further configured to draw, in a case the operating tool contacts a drawing area on the screen, a dot at a contact position of the operating tool with a density according to the amount of ink assumed to have been attached to the operating tool,the processor decreases the amount of ink assumed to have been attached to the operating tool every time a dot is drawn by the drawing unit, andthe processor decreases the density of a dot to be drawn in the drawing area every time the amount of ink assumed to have been attached to the operating tool is decreased.

7. A parameter setting method performed by an information processing apparatus including circuitry configured to detect a contact position of an operating tool which has contacted a screen, detect a contact area size of the operating tool which has contacted the screen, and detect a pressure of the operating tool pressing the screen, comprising:
-
setting, according to the contact area size of the operating tool on an object displayed on the screen and the pressure of the operating tool pressing the object, an amount of ink assumed to have been attached to the operating tool; drawing, in a case the operating tool contacts a drawing area on the screen, a dot at a contact position of the operating tool with a density according to the amount of ink assumed to have been attached to the operating tool; decreasing the amount of ink assumed to have been attached to the operating tool every time a dot is drawn by the drawing unit; and decreasing the density of a dot to be drawn in the drawing area every time the amount of ink assumed to have been attached to the operating tool is decreased, wherein the object is provided for each colour.

8. A non-transitory computer-readable storage medium storing computer-readable instructions thereon, which, when executed by a computer, cause the computer to perform a method comprising:
-
detecting a contact position of an operating tool which has contacted a screen; detecting a contact area size of the operating tool which has contacted the screen; detecting a pressure of the operating tool pressing the screen; and setting, according to the contact area size of the operating tool on an object displayed on the screen and the pressure of the operating tool pressing the object, an amount of ink assumed to have been attached to the operating tool; drawing, in a case the operating tool contacts a drawing area on the screen, a dot at a contact position of the operating tool with a density according to the amount of ink assumed to have been attached to the operating tool; decreasing the amount of ink assumed to have been attached to the operating tool every time a dot is drawn by the drawing unit; and decreasing the density of a dot to be drawn in the drawing area every time the amount of ink assumed to have been attached to the operating tool is decreased, wherein the object is provided for each colour.
