This specifies a symbol height of 100 times the X-dimension of the symbol.
The switch --compliantheight changes the default height to be compliant with the
barcode standard (if any). For instance
The default height of most linear barcodes is 50X, but this can be changed for
barcodes whose specifications give a standard height by using the switch
--compliantheight. For instance
zint -b LOGMARS -d "This Text" --compliantheight

The switch --heightperrow is useful for symbologies that have a variable number
of linear rows, namely PDF417, MicroPDF417, Codablock-F, Code16K, Code 49 and
DataBar Expanded Stacked, as it changes the treatment of the height value from
overall height to per-row height, allowing you to specify a consistent height
for each linear row without having to know how many there will be. For instance
