If you’re putting large numbers of PDF documents through the toolkit then you might be very interested in taking a closer look at this version; image-only PDF documents now process at around 3X the speed of previous versions and with higher accuracy. Developers wanting to get hold of the update to the PDF Extension will
Overview CodabarMaxVariance is the maximum percentage variance that a character in a codabar barcode can have from the average for that barcode. Type: SHORT Default value: 20 Note: This is an Advanced property and can only be set using LoadXMLSettings
Overview When True the toolkit will only report Code 25 barcodes where the last character is a valid checksum for the rest of the barcode. The toolkit expects a Code 25 checksum to be calculated using the following method: Sum all of the even positioned characters (the right hand message character is always even), and multiply by 3.
Overview ColorChunks specifies how many sections a scan line of an image should be broken into when calculating threshold levels for black and white pixels. Type: SHORT Default value: 1 Note: This is an Advanced property and can only be set using LoadXMLSettings
Overview If the Despeckle property is set to TRUE and the NoiseReduction property is none zero, then the toolkit removes white speckles inside the bars of a barcode before removing black marks from the spaces between bars. Type: BOOL Default value: FALSE
Overview The Encoding property controls the format in which the toolkit returns strings for barcode types that use full symbol sets such as PDF-417. The property can take any of the following values: 0 Raw , with null characters suppressed. 1 Quoted printable 2 Unicode 3 UTF-8 Type: SHORT Default Value: 0
Overview If GammaCorrection is set to a value other than 100 then the toolkit will apply gamma correction to a color image. The amount of gamma correction is equal to GammaCorrection / 100. For example, to achieve a gamma correction of 0.5 the property should be set to a value of 50. Type: SHORT Default value: 100
Overview Use the LicenseKey property to set your license key prior to calling the ScanBarCode, ScanBarCodeFromBitmap or ScanBarCodeFromDIB functions. With no license key the .net interface will return all barcode values as“Please contact sales@bardecode.com for a trial license string” and other interfaces will display a pop up box that the user will need to click on to continue. Type: STRING Default
Overview Overview As the SDK scans an image it assigns a score to each barcode candidate. At the end of a scan, any candidates with a score >= PrefOccurrence are reported by the SDK. If no candidate meets this criteria then the SDK selects the candidate with the highest score and reports this barcode if it
Overview Output information about the structure and cluster values of the barcode. The debug information is returned in place of the normal barcode value (see GetBarString). The fields of the string are as follows: Error correction status – true or false Number of data columns Number of rows Error correction level Number of unknown cluster
