The ScanBarCodeFromBitmap function allows you to read bar codes from memory bitmaps rather than image files held on disk. The function takes a handle to a bitmap as the parameter rather than the path to a file containing the image. It is normally referred to as an HBITMAP by programmers. You can create a bitmap
This article discusses how to use BardecodeFiler to collate pages containing the same bar code value from various PDF documents. For example, say you receive orders from customers and each order form contains a bar code that identified the customer with a unique code. You scan the order forms in random batches as they are
The main changes for version 7.6.1 are in the areas of performance control and recognition of skewed bar codes. Performance Control TimeOut is a new property that specifies the maximum amount of time the toolkit should spend searching for a barcode within a single page of a document. It does not include the time taken
If whilst trying to use the Softek Barcode Reader Toolkit it returns to error message “Failed to load SoftekBarcode.dll” then a possible cause of the problem may be that you have the wrong version of the .dll for the system you are using. The following should help to remedy this problem: When you create an
We have had a number of requests for a full list of the possible return values for the GetBarStringType function in Version 7.5.1.35 of the SDK. Below are the possible return values from this function: PDF417 DATAMATRIX QRCODE CODE39 EAN13 EAN8 UPCA UPCE SHORTCODE128 CODE128 GS1-128 PATCH DATABAR CODE93 CODE25 SHORTCODE128 CODABAR For further information on
This article explains issues relating to the use of UTF-8 encoded data in QR-Codes. There are several ways in which data can be stored in a QR-Code, one of which is called Byte Mode. This mode allows data to be encoded in a sequence of 8-bit byte values, in other words an array of integer
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
