Generally, this component does not validate the encoded data. It is up to the developer to ensure data is of the correct format before feeding it to this class for encoding. This component does not manage quiet zones. See the specification files for some notes on required quiet zone widths.
Explicit dimensions will work, but it is recommended to use measured dimensions because in that case encoded data will be displayed using whole pixels. Explicit dimensions may use partial pixels and therefore be harder for barcode readers to decode. To control the relative size of measured bar codes, use the "resolution" property.
For the 1-D barcodes (with measured dimensions), the line width is determined directly by the "resolution" property which in turn determines the measured width.
In summary, explicit dimensions are allowed, but this may cause partial pixels to be drawn and therefore be harder for a barcode reader to read. Use measured dimensions and control the relative size via the "resolution" property.
