This pull request adds 2 parameters to
decode(): x_density, and y_density both of which (should) map to the zbar scan density parameters. This modification was helpful in another project and thought it may be useful to offer the pull request in light of: #30.Important note: Please see my comments in
decode()concerning my use of 0 in 2nd parameter when calling thezbar_image_scanner_set_config(). I must admit I do not understand that parameter's use beyond symbology.Hope it helps!
