Symbol Dimensions
Height of longest bar, in inches.
A 1/2 inch tall EAN-13:
Data: 9520123456788
Options: includetext height=0.5
Encoder: ean13
Stretch the symbol to precisely this width, in inches.
- This parameter literally stretches the symbol and text to the desired width which may distort the human readable text.
- For information about resizing symbols read the article on resizing symbols.
A 2 inch wide Code 93 symbol:
Data: TERRY
Options: width=2
Encoder: code93
When enabled, the renderer snaps symbol elements to device pixel boundaries, producing crisp output at the target resolution.
This is most useful for non-vector formats rendered at low resolutions where bar or module stability may adversely affect validity or scanning performance.
- Gridfit is automatically disabled for:
- Symbologies with fractional bar widths (e.g. postal codes, Pharmacode).
- Linear barcodes with a non-integer barratio.
- The device resolution is probed Unless gridfit is provided.
Data: 9520123456788
Options: includetext gridfit
Encoder: ean13
Specify the target resolution for pixel-aligned rendering, in dots per inch. This can be useful if the target device's resolution cannot be probed.
Setting griddpi automatically enables gridfit.
Data: TESTING
Options: griddpi=300
Encoder: qrcode
