This Y multiplier allows the user to specify the height of bars in the barcode. The value here is multiplied by the X dimension to produce the actual height of the bars. Note that this value is ignored for barcodes with square elements (eg. Aztec and DataMatrix).
Note that the metafile image produced by dBarcode may be resized independently of the target size, although the sizes stored within the metafile will be those derived from the bar element dimensions defined in this dialog.
