Algorithm (for each 4x8 pixel cell mapped to a unicode block graphics character):
|
|
|
|
|
|
|
|
|
|
|
|
1. Find the color channel that has the biggest range of values for the current cell
|
|
|
|
|
|
2. Split the range in the middle
|
|
|
|
|
|
3. Average the colors above and below and create a corresponding bitmap for the cell
|
|
|
|
|
|
3. Compare the bitmap to the assumed bitmaps for the unicode block graphics characters
