%description
There are various similar tools (such as timg) using the unicode half block character to display two 24bit pixels per character cell. This program enhances the resolution by mapping 4x8 pixel cells to different unicode characters, using the following algorithm:

For each 4x8 pixel cell of the (potentially downscaled) image:

    Find the color channel (R, G or B) that has the biggest range of values for the current cell
    Split this range in the middle and create a corresponding bitmap for the cell
    Compare the bitmap to the assumed bitmaps for various unicode block graphics characters
    Re-calculate the foreground and background colors for the chosen character
