Set software to implement functions optical recognition barcodes various systems using a conventional webcam, as well as displaying them in printed forms. Programs can work as part of configurations created on the basis of 1C-Enterprise platforms versions 7.7, 8.2, 8.3. The code reading component is implemented as an external 1C component with a COM interface. The display component is created using standard ActiveX technology for Windows, and can be embedded in any application that supports embedding ActiveX controls, for example, in word document or Excel, or a VBA form. P.S. Added a new version recognition programs. New features: video processing in real mode (and not by timer, as before), added the ability to recognize barcodes from graphic JPEG files, PNG, GIF, BMP, as well as transfer images from 1C for recognition, now you can get an image captured from a camera or file in 1C, both with and without highlighting places containing codes, as well as individual fragments of images containing code. Added new properties and methods for programming. Updated documentation.
Working with the camera is implemented using DirectX technology and requires DirectX installed in the system, as well as support for this technology by the webcam (almost all modern cameras, including budget ones, support DirectX).
Software bundle:
- ActiveX component for printing barcodes
- External component for camera video capture and barcode recognition
- Operating Instructions (with detailed description each supported barcode type)
- An example of external processing for 1C 8.2
The program is provided as an installer, the entire installation process takes place in the installation wizard automatically, with a request for installation parameters from the user. Installation can be carried out both for one user and for the entire system.
The following freely distributed libraries were used in the development:
Zint– barcode display library
Zbar– barcode recognition library
Fork of the Zint function library for Delphi http://theunknownones.net
Using the ActiveX component barcontrol.ocx
The barcode display and print program is an ActiveX control with all the consequences that implies. This means that you can use this component to embed in any application that supports ActiveX component integration, for example, Microsoft Word, Microsoft Excel, other products from the composition Microsoft Office. You can embed the component in a document, as well as place it on the forms of VBA applications. But still, the main purpose of the component is to embed 1C-Enterprise versions 7.* and 8.* into printable templates.
Embedding in a 1C 7.7 template
1C 7.7 does not support embedding controls directly from the configurator menu. To embed a control in a layout printed form 1C 7.7, insert it first into Microsoft Word or any other application that supports embedding ActiveX controls. Then select the element with the mouse button and copy it to the clipboard (Ctrl + C). After that, go to the layout editing form in the 1C configurator and paste the element from the clipboard to the selected location (Ctrl + V).
Embedding in a 1C 8.2 template
To embed an element in the layout of a spreadsheet document 1C 8.2, select the menu items "Table/Pictures/Insert Object" from the main menu of the configurator. Click in right place layout with the mouse pointer, and select the area in which the element will be located. After you have completed the selection, a standard window for inserting objects of the Windows system will appear on the screen. Select "CBarGenerator control" from the list. After pressing the "Ok" button, the element will appear in the designated area.
Setting object properties from the configurator
Highlight the element "CBarGenerator" in the printable template in the configurator with the mouse pointer, and click right click. Select "CBarGenerator Control/Properties" from the menu that appears. In the window that appears, you can change the barcode type, data, color, text font, indents, etc. (the values of the properties available for editing are described in the Application Programming Interface section).
When you change any of the settings, the "Apply" button becomes available, with which you can view the resulting changes without closing the settings window. When you click the "Ok" button, all the changes made are applied to the object, and the settings window is closed.
Programmatic management of object properties from 1C 7.7
Select the element "CBarGenerator" with the mouse pointer in the printable template in the configurator "1C-Enterprise" 7.7, and right-click. Select "Properties" from the menu that appears.
In the "Decryption" field, put the name of the function that will be called for the decryption receive event. When this function is called, the "CurrentObject" template property will point to our control, so here you can change any of the properties described in the "Application Programming Interface" section. Example program code:
Procedure PrintDocument() Tab = CreateObject("Table"); PechCode = "012345678934"; PrintType = 34; Tab.OutputSection("SectionBarCode"); ... Tab.Show("Barcodes"); EndProcedure GetDecryption() Function Tab.CurrentObject.BarType = PrintType; Tab.CurrentObject.BarData = PechCode; EndFunctions
Programmatic management of object properties from 1C 8.2
Select the “CBarGenerator” element with the mouse pointer in the spreadsheet document layout in the configurator, go to the “Figure Properties” tab and give it a name.
Now you can access the object from the program code using given name. You must first display the layout in the resulting spreadsheet document. Program code example:
Procedure PrintDocument() TabDocument = FormElements.TableDocumentField; TabDocument.Clear(); TabDocument.PrintParameterName = "Barcoding_Parameters"; Layout = GetLayout("Layout"); Header Area = Layout. GetArea("Header"); TabDocument.Output(HeaderArea); TabDocument.Drawings.DBarCode.Object.BarType = CodeType; TabDocument.Drawings.DBarCode.Object.BarData = StringData; EndProcedure

Working with the recognition component
The barcode recognition component is implemented using DirectX to capture the video stream from the camera. The stream is split into individual frames, which are then analyzed for one or more images of barcode symbols. When symbols are detected, they are highlighted in the scanning window with a bright line, and information about recognized symbols, such as decrypted data, type of barcoding, the angle at which successful recognition was performed, is transmitted using an external event to the 1C- Company".
Use in programs 1C 7.7, 8.2
The recognition component is designed as an external component for 1C systems, and can be built into the program in a standard way for 1C:
In the global module:
Variable ScannerObject Export; System Startup Procedure() ScannerObject = Null; Attempt to ConnectExternalComponent("AddIn.OBRScannerVK"); ScannerObject = New("AddIn.OBRScannerVK"); Exception Report("Could not load component!", MessageStatus.Important); Report("1. Check if all component files are copied to the directory " +ProgramDirectory(), MessageStatus.Attention); Send("2. Check if a Firewall is installed on the computer that blocks the download of the component!", MessageStatus.Attention); Report(ErrorDescription(), MessageStatus.Attention); End of Attempt; EndProcedure
To call the scanning window and start the scanning procedure, use the "ShowScanWindow()" function:
Procedure ButtonExecutePress(Button) If ScannerObject<>Null Then ScannerObject.ShowScanWindow(); EndIf; EndProcedure
After the program has recognized the barcode, it sends to 1C a string in which the recognized data is encrypted, the type of the barcode, add. options, the angle of rotation at which recognition occurred. The data string is encoded with the Base64 algorithm. To decode, use the "DecodeBase64" function of the component.
Procedure ExternalEvent(Source, Event, Data) DataString = ""; Tokens = StrReplace(Data,";", Symbols.PS); CodeType = 1; Angle = 0; For Sn=1 By StrNumber Of Rows(Tokens) Loop StrToken = StrGetString(Tokens, Sn); Index = Find(StrToken,":"); If Index > 1 Then TokenName = Left(StrToken, Index-1); TokenValue = Avg(StrToken, Index+1); If TokenName = "data" Then DataString = ScannerObject.DecodeBase64(TokenValue); ElseIf TokenName = "angle" Then Angle = Number(TokenValue); ElseIf TokenName = "symbol" Then StrTypeBarCode = HReg(TokenValue); If StrTypeBarCode = "ean-13" Then CodeType = 21; ElseIf StrTypeBarCode = "ean-8" Then CodeType = 21; ElseIf StrTypeBarCode = "upc-e" Then CodeType = 23; ElseIf StrTypeBarCode = "upc-a" Then CodeType = 22; ElseIf StrTypeBarCode = "isbn-13" Then CodeType = 40; ElseIf StrTypeBarCode = "i2/5" Then CodeType = 2; ElseIf StrTypeBarCode = "code-39" Then CodeType = 7; ElseIf StrTypeBarCode = "code-128" Then CodeType = 11; ElseIf StrTypeBarCode = "pdf417" Then CodeType = 31; ElseIf StrTypeBarCode = "qr-code" Then CodeType = 34; EndIf; EndIf; EndIf; EndCycle; EndProcedure
Setting the recognition parameters in the 1C system
After loading the component in the 1C system, the settings panel appears new inset where you can configure the following settings:
- Video capture device - allows you to select the video device used for reading, if there are several of them in the system.
- Rotate the image - allows you to achieve a more accurate quality of recognition by enough powerful computers, rotating the image by 15% to 90% until the barcode symbol is found in the image.
- Types of barcodes - selection of types of barcodes, the presence of which in the image will be tried by the program. The program can recognize the following types bar codes: EAN-8, EAN-13, UPC-A, UPC-E, ISBN-10, ISBN-13, Code-39, PDF-417, Qr-Code, Code 128, Interleaved 2 of 5.
- Camera resolution - setting the recognition accuracy;
- Check data correctness - check whether the recognized data for a certain type of code complies with the standard;
- Stop scanning after recognition - stop the scanning process after character recognition;
- Close window after recognition - close the scanning window after character recognition.
Recognition component software interface
Properties:
Picture- reading, writing. Setting a picture for recognition. There are two options for setting this property:
1: The property value is set to the name of the image file. In this case, the component tries to load the image file from the disk at the specified path and determine the type of its content. Available types graphic files– JPEG, PNG, GIF, BMP.
2. The value of the property is set to a string containing binary data encoded by the Base64 algorithm obtained from the 1C image:
ScannerObject.Picture = Base64String(Picture.GetBinaryData());
When reading a value from this property, the component always returns the binary data of the current image loaded from disk or captured from the camera, encoded with the Base64 algorithm. You can get a finished 1C picture as follows:
Image1C = New Image(Base64Value(Scanner.Picture));
CharacterTypes (SymbolTypes) - reading, writing. Set/read barcode types available for use. The value is a string containing the symbolic names of barcode types, separated by a comma. Possible values are: "ean-13", "ean-8", "upc-e", "upc-a", "isbn-10", "isbn-13", "i2/5", "code-39 ", "code-128", "pdf417", "qr-code".
RotatePicture (RotateBitmap) - reading, writing. Contains a boolean value - true or false. If set to True, the image will be rotated in increments of 15 degrees, up to 90 degrees, for the best possible recognition.
Horizontal Resolution (DensityX) - reading, writing. Allows you to set the horizontal resolution of the camera, a number from 1 to 10 is set. The smallest resolution is 1.
Vertical Resolution (DensityY) - reading, writing. Allows you to set the vertical resolution of the camera, a number from 1 to 10 is set. The smallest resolution is 1.
Methods:
ShowScanWindow– Show the scanning window, enable data acquisition from the video camera and start the process of barcode symbol recognition.
DecodeBase64 (DecodeBase64)– Decoding of the data string encrypted with the Base64 algorithm passed from the external component to the external event handler.
EncodeBase64(EncodeBase64)– Data string encoding 1C with Base64 algorithm. For use in future versions of the component.
ScanPicture– Scanning the picture passed to the component in the "Picture" property for barcodes. The decoded data is returned to the program as a string. The string can be decrypted using the following 1C code:
Function GetDataFromString(StringCodes) DataArray = New Array; For It = 1 By StrNumber of Lines(StrCodes) Loop CodeType = 0; StringData = ""; Rotation Angle = 0; StrTypeBarCode = ""; Data = StrGetString(StRCodes, It); Tokens = StrReplace(Data, ";", Symbols.PS); For Sch = 1 By StrNumber Of Rows(Tokens) Loop StrToken = StrGetString(Tokens, Sch); Index = Find(StrToken,":"); If Index > 1 Then TokenName = Left(StrToken, Index-1); TokenValue = Avg(StrToken, Index+1); If TokenName = "data" Then DataString = ScannerObject.DecodeBase64(TokenValue); ElseIf TokenName = "angle" Then Rotation Angle = Number(TokenValue); ElseIf TokenName = "symbol" Then StrTypeBarCode = HReg(TokenValue); EndIf; EndIf; EndCycle; StrResult = New Structure("CodeType Str, Angle, Data", StrTypeBarCode, Rotation Angle, String Data); DataArray.Add(StrResult); EndCycle; Return ArrayData; EndFunctions
GetFragment (GetFragment)– returns a fragment of the original drawing containing the detected barcode symbol. The picture is returned as a string encoded with the Base64 algorithm (the decryption method is given in the description of the "Picture" property). The sequence number of the detected character is passed to the function as a parameter, the first fragment is denoted by one.
