barcode(fxhash) converts the ascii characters from the transaction hash of the token (fxhash variable) into barcodes for each of 51 characters. It uses Code 39 (https://github.com/graphicore/librebarcode), so it is not case sensitive. Each iteration has from 1 to 8 columns, and from 1 to 8 rows, and the frist N characters of the fxhash are displayed in one of first N positions (first 2 characters 'oo' are discarted). f the number of characters is greater than 49 (length of fxhash discarting 'oo'), the boxes will continue to be filled, returning from the third character of fxhash.

Features generated by fxrand() random function:

-num_chars: number of characters displayed. from 1 to 64. They are the first N characters of fxhash.
-has_fxhash: this boolean value indicates whether fxhash contains the letters needed to form the word 'fxhash'.
-show_fxhash: this boolean value indicates whether fxhash contains the letters needed to form the word 'fxhash' and these are all displayed.
-columns: number of columns (1-8).
-rows: number of rows (1-8).
-color_mode: color mode white (light) or black (dark).
-separacio: factor of separation between barcodes (1.1, 1.5 or 2)
-scale_type: scale type (none, all, random, only rows, only columns, etc..)
-rotate_type: rotation type (none, all, random, only rows, only columns, etc..)
-transparent: this boolean value indicates whether the barcodes has a transparent background.
-squares: this boolean value indicates whether the barcodes width=height.
-main_shadow: blur value for main shadow.
-exterior_shadow: exterior shadow type rotation type (none, all, random, only rows, only columns, etc..)
-interior_shadow: exterior shadow type rotation type (none, all, random, only rows, only columns, etc..)
