# Let's assume an Input image with only a row of all character glyphs (no double rows...)
# BLADE RUNNER:
# TODO: A way to differentiate between corrupted TAHOMA18 and extended TAHOMA18 (user created)
# TODO: Maybe instead of removing transparency from glyph ROW image (transparency threshold= 0), use a grey gradient for semitransparent pixels for the cases of TAHOMA fonts (and maybe the subtitle ones too)
#           Create the font row in GIMP - add layers for shadows if necessary
#           Merge all layers (maintaining an alpha channel for the background)
#           Select all and float, which should create a floating selection with all the letters
#           Promote that to layer and duplicate it.
#           Choose one of the duplicated layers and COLORIFY it to PITCH BLACK
#               Set the transparency threshold of THAT black layer to 0
#           Put this layer under the other and merge the visible layers.
#           This should get rid of semi-transparent pixels while maintaining the "aliasing" effect. There could be a better way but this should work ok.


# TODO: A way to export game fonts to png image (in order to be able to create new expanded fonts keeping glyph consistency!)
#           Also override the corruption in TAHOMA18 while exporting
# TODO: Re-Check the order of fonts in (in-game resource font files) TAHOMA18 (stored corrupted) and TAHOMA24 (in good condition).
# TODO: print a warning for mismatch of number of letters in encoding override (or internal) and detected fonts in ROW IMAGE (especially if we expect a double exclamation mark at the start - and we ignoring one of the two)
# TODO: Don't crash if mismatch in detected letter (fewer) in row image vs the letters in ascii list of overrideEncoding file
# TODO: A more detailed readme for this tool and how to use it
#
# DONE: enforce overrideEncoding.txt -- this tool should no longer work without one
# DONE: Test greek subs too
# DONE: Letter fonts should be spaced by TAB when copied into GIMP or other app to create the image row of all character glyphs
# DONE: First character should be repeated in the ROW file (but taken into consideration once) in order to get the pixels for the TAB space between letters (left-start column to left-start column)
# DONE: Use the tab space pixels to calculate the KERNING for each letter (x offset)
# DONE: update the image segment size bytes in the header after having completed populating the image segment
# DONE: allow settin explicit kerning and width addon for cases like i and l characters
# DONE: entrée (boiled dog question) - has an e like goose liver pate --> TESTED
# DONE: Tested ok "si senor" from peruvian lady / insect dealer too!
# DONE: ability to manually set kerning (x-offset) for fonts by letter like a list in parameters or in overrideEncoding.txt }  i:1,j:-1,l:1	 (no space or white line characters) - POSITIVE OR NEGATIVE VALUES BOTH ADMITTED
# DONE: a value of '-' for this means ignore
# DONE: ability to manually set extra width (additional columns at the end of glyph, with transparent color) for fonts by letter like a list in parameters or in overrideEncoding.txt }	 i:1,j:2,l:1 - POSITIVE VALUES ONLY
# DONE: make space pixels (var spaceWidthInPixels) into an external param?
# DONE: INFO NOTE IT IS NOT POSSIBLE TO have partial transparency
