===== DRAWING THE GHOST =====

{{:midres_library:tutorial:mctile:mctiles_tutorial_02.png?nolink&200 |}}

First of all, we have to find an image of the ghost or draw it freehand (as I did). Usually, we draw it at a rather high resolution. In this example we start from 118x118 pixels. 

Note that when drawing the image, we should leave a black border on the left and right. The image thus drawn is, however, too large to be managed by 8-bit computers. 

For this reason, we proceed to resize the image to a more suitable size, such as 16 pixels x 16 pixels. Note that we must impose "None" as a quality to avoid introducing additional nuances.\\\

Once converted it is necessary to reduce the number of colors present in the image. This is necessary because the ''[[:img2tile]]'' program automatically detects the colors (as RGB) and assigns them to the 2-bit indices which, in fact, can only indicate 4 different colors.

Finally, before going back to processing the image, you need to convert it back to RGB in order to be free to assign precise colors.
