.SH DESCRIPTION
.IX Header "DESCRIPTION"
A Barcode::ZBar::ImageScanner is used to scan for bar codes in a
Barcode::ZBar::Image.
.SH REFERENCE
.IX Header "REFERENCE"
.SS Methods
.IX Subsection "Methods"
.IP \fBnew()\fR 4
.IX Item "new()"
Create a new bar code image scanner instance.
.IP \fBget_results()\fR 4
.IX Item "get_results()"
Return a list of Barcode::ZBar::Symbol results from the last scanned
image.
.IP scan_image([\fIimage\fR]) 4
.IX Item "scan_image([image])"
Scan a Barcode::ZBar::Image for bar codes.  The image must be in the
"Y800" format.  If necessary, use \f(CW\*(C`\fR\f(CI$image\fR\f(CW\->convert("Y800")\*(C'\fR to
convert from other supported formats to Y800 before scanning.
.IP enable_cache([\fIenable\fR]) 4
.IX Item "enable_cache([enable])"
Enable the inter-image result consistency cache.
.IP "set_config(\fIsymbology\fR, \fIconfig\fR, \fIvalue\fR)" 4
.IX Item "set_config(symbology, config, value)"
Set config for indicated symbology (0 for all) to specified value.
.IP parse_config(\fIconfigstr\fR) 4
.IX Item "parse_config(configstr)"
Apply a decoder configuration setting.  See the documentation for
\&\f(CW\*(C`zbarcam\*(C'\fR/\f(CW\*(C`zbarimg\*(C'\fR for available configuration options.
.IP recycle_image([\fIimage\fR]) 4
.IX Item "recycle_image([image])"
Remove previously decoded results from a Barcode::ZBar::Image and
recycle the associated memory.
