In combination with the dynamic up/down sizing to fit whitespace, we get pretty good output images Also removed the check that we do not resize the font size that much fixes #13

# @brief This program converts supported tablature source files to a printable format
|
|
#
|
|
# @section description Description
|
|
# Creates Song objects of all tablatures it can find in a given directory or its subdirectories
|
|
# Supported inputs currently: Any .txt file, as long as each section has a corresponding [<sectionName>] delimiter
|
|
# Supported outputs currently: PNG format
|
|
# Song objects are then parsed into separate metadata information and sections
|
|
# Sections contain lines of lyric and corresponding tablature data
|
|
# The program then tries to fit these sections within the chosen output dimensions (currently A4)
|
|
# as best as it can, shrinking or growing sections to fit the remaining space
|
|
#
|
|
# @section notes Notes
|
|
# - Splitting raw text into lyric and tablature info is very basic at the moment.
|
|
# We need a better way to classify & split the various channels (raw tab, lyrics, chords, more?) that can be expected in tablature
|
|
#
|
|
# @section todo TODO
|
|
# - Various prints should be printed at specific log levels, to easily switch between debug, info or warnings only
