5	5		### About
6	6
7	7		LazBarcodes is a set of controls to create 1D and 2D barcodes. The backend engine is a port of [Zint](http://sourceforge.net/projects/zint/) at sourceforge. Some units were heavily refactored to obtain a more Pascal-like code.
8	8
9	9		The library supports the generation of 1D and 2D barcodes:
10	10
11	11		- 1D barcodes: Code-11, Code-128, Channel code, EAN-128, several 2-of-5 variants, several 3-of-9 variants, EAN, UPC, Plessey, MSI/Plessey, Telepen, medical/pharmaceutical codes (CodaBar, Code-32, Pharma one-track, Pharma two-track, PZN), postal codes (Australian post, Japanese post, Korean Post, Deutsche Post IdentCode and LeitCode, Dutch KIX, Planet, PostNet, Royal Mail RM4SCC)
12	12		- Stacked barcodes: PDF417, compact PDF417, MicroPDF417
13	13		- 2D barcodes: QR, MicroQR, Aztec, Aztec Rune, Data Matrix, Maxicode

19	19		### License
20	20
21	21		BSD 3 as it is being inherited from the zint source code.
22	22
23	23		### Dependencies / System Requirements
24	24
25	25		- None
26	26
27	27		## Getting LazBarcodes
28	28
29	29		The download contains the packages lazbarcodes and lazbarcodes_runtimeonly. The first one gives you visual components of the above barcodes and the second can be used just to access the ported zint code for advanced barcode generation.
30	30
31	31		### Development version
32	32
33	33		The latest source code can be found on [Lazarus-CCR](https://sourceforge.net/p/lazarus-ccr/svn/HEAD/tree/components/lazbarcodes/). Use SVN to load the source files, or download the "Snapshot" by clicking on the corresponding button of the sourceforge site and unzip it to some directory. For installation go to "Package" \> "Load package file (.lpk)", navigate to the folder with the downloaded sources and load the fole lazbarcodes_runtimeonly.lpk. Then load the package lazbarcodes.lpk*. Click "Use" \> "Install", and confirm the question to rebuild the IDE. After some time the IDE restarts, and you find the barcodes in the "LazBarcodes" tab of the component palette.
34	34
35	35		### Release version
36	36
37	37		Occasionally a release version is prepared and made available for easy installation by means of the [[Online Package Manager\|Online-Package-Manager]] in the Lazarus IDE. Open "Package" \> "Online package manager", check the item "LazBarcodes" in the list and click "Install". Again, confirm the question to rebuild the IDE. When the IDE restarts after some time you find the barcodes in the "LazBarcodes" tab of the component palette.

39	39		### Change Log
40	40
41	41		- v2.0.0: Added a lot of 1D barcodes
42	42		- v1.0.3: Internally used units renamed to avoid naming conflict with CodeTyphon package PL_APE.
43	43		- v1.0.2: Change of license from GPL to BSD
44	44		- Initial development.

48	48		### General
49	49
50	50		The components installed by the LazBarcodes package descent from TGraphicControl and thus inherit fundamental control properties such as `Width`, `Height`, `AutoSize`, etc. They share a variety of other properties and methods; some properties, however, are not published fwhen they are not appropriate for the current barcode type.
51	51
52	52		#### Properties
53	53
54	54		- `Text: TCaption` - Text to be encoded as a barcode. Note that, depending on the barcode type, there exist limitations on allowed text length and allowed characters.
55	55		- `ShowHumanReadableText: Boolean` - Displays the encoded text underneath the barcode symbol. Note that the encoding algorithm may add check sum or additional characters to the input text.
56	56		- `BarcodeType` - Some barcode components can be modified to create various symbologies by selecting the corresponding value in this (type-dependent) enumeration.
57	57		- `Scale: Integer` - Horizontal scaling factor of the barcode determining the width of the smallest feature (bar or space) in pixels. `Scale=0` tries to select an internal scale value such that the barcode fills the control's width as much as possible. Note that this scaling factor applies to all bars and spaces and therefore, increasing `Scale` does not increase the barcode with gradually but by more or less large steps.
58	58		- `SymbolHeight: Integer` - Similar to `Scale`, but refers now to the vertical direction. Again, `SymbolHeight=0` fills adjusts the internal symbol height to fill the height
59	59		- `MinSymbolHeight: Integer` - Prevents the symbol to become too small.
60	60		- `RecommendedSymbolSize: Boolean` - If `true`, overrides the `Scale` and `SymbolHeight` settings so that the size of the symbol is as close as possible to its specification.
61	61		- `AutoSize: Boolean` - inherited standard property. When `true`, `Width` and `Height` are selected such that the current size of the barcode is enclosed. Note that `AutoSize=true` is ignored when `Scale=0` or `SymbolHeight=0`.
62	62		- `Margin: Integer` - Amount of empty pixels added around the symbol
63	63		- `WhitespaceWidth: Integer` - Amount of empty pixels added to the left and right of some symbologies to enhance readability of barcode scanners.
64	64		- `BearerBarMode: TBearerBarMode = (bbmNone, bbmBearerBars, bbmBox)` - adds horizontal bars above and below the barcode (`bbmBearerBars`) or a box around the barcode (`bbmBox`). The thickness of the bars and the box border is given by the `Margin` multiplied by the currently used internal `Scale` parameter.
65	65		- `ForegroundColor: TColor` - Color used to draw the bars
66	66		- `BackgroundColor: TColor` - Color used to draw the background of the barcode (spaces, margin and text area).
67	67
68	68		#### Methods
69	69
70	70		- `CopyToClipboard` - Copies the barcode to the clipboard as a bitmap
71	71		- `SaveToFile(const AFileName: String; AImageClass: TFPImageBitmapClass)` - Saves the barcode as a graphic image of the specified class to file.
72	72		- `SaveToStream(const AStream: TStream; AImageClass: TFPImageBitmapClass)` - Saves the barcode as a graphic image of the specified class to a stream.
73	73		- `SaveToEPSFile(const AFileName: String)` - Saves the barcode as EPS file
74	74		- `SaveToEPSStream(const AStream: TStream)` - Saves the barcode in EPS format as stream.
75	75		- `SaveToSVGFile(const AFileName: String)` - Saves the barcode in SVG format to file
76	76		- `SaveToSVGStream(const AStream: TStream)` - Saves the barcode in SVG format to a stream
77	77		- `ErrorString: String` - In case of an error, this read-only property contains a message why the `Text` could not be encoded correctly.

193	148		#### Special properties of some components
194	149
195	150		- `TBarcodePlessey`
196	151		- `CheckChar: TPlesseyCheckChar` - determines the checksum digit(s) added to the MSI/Plessey symbol (used only when `BarcodeType = bctMSIPlessey`):
197	152		- `pcOneMod10`: adds one check digit calculated by a mod 10 algorithm
198	153		- `pcTwoMod10`: adds two check digits, both calculated by a mod 10 algorithm
199	154		- `pcOneMod11`: adds one check digit calculated by a mod 11 algorithm
200	155		- `pcOneMod10Mod11`: add two check digits, the first one calculated by a mod 10, the second one calculated by a mod 11 algorithm.
201	156		- `TBarcodeQR`
202	157		- `ECCLevel: TBarcodeQR_ECCLevel` - determines the level of error correction (used also by `TBarcodeMicroQR`):
203	158		- `eBarcodeQR_ECCLevel_Auto`: selects one of the other options depending on data length
204	159		- `eBarcodeQR_ECCLevel_L`: Error correction capacity: approx 20% of symbol, recovery capacity: approx 7%
205	160		- `eBarcodeQR_ECCLevel_M`: Error correction capacity: approx 37% of symbol, recovery capacity: approx 15%
206	161		- `eBarcodeQR_ECCLevel_Q`: Error correction capacity: approx 55% of symbol, recovery capacity: approx 25%
207	162		- `eBarcodeQR_ECCLevel_H`: Error correction capacity: approx 65% of symbol, recovery capacity: approx 30%
208	163		- `TBarcodeMaxicode`
209	164		- `Mode: TBarcodeMaxicodeMode` - message mode
210	165		- `mcmAuto`: tries to determine the mode from the type of the data
211	166		- `mcmMode2`: In addition to the `Text` ("secondary message") also a 15-digit "primary message" must be provided in the property `Primary`. It consists of 9 numerical digits for the US-domestic post-code (property `PostCode: String`), 3 numeric digits for the country code (ISO 3166, property `CountryCode: Integer`) and 3 numeric digits for the service code (property `ServiceCode: Integer`).
212	167		- `mcmMode3`: In addition to the `Text` ("secondary message") also a 15-digit "primary message" must be provided in the property `Primary`. It consists of 6 alphanumeric digits for the international post-code (property `PostCode: String`), 3 numeric digits for the country code (ISO 3166, property `CountryCode: Integer`) and 3 numeric digits for the service code (property `ServiceCode: Integer`).
213	168		- `mcmMode4`: No `Primary` needed.
214	169		- `mcmMode5`: No `Primary` needed.
215	170		- `mcmMode6`: No `Primary` needed.
216	171		- `Primary: String` - see `TBarcodeMaxicode.Mode`
217	172		- `PostCode: String` - see `TBarcodeMaxicode.Mode`
218	173		- `CountryCode: String` - see `TBarcodeMaxicode.Mode`
219	174		- `ServiceCode: String` - see `TBarcodeMaxicode.Mode`
220	175
221	176		### Demo application
222	177
223	178		A demo project is contained in the LazBarcodes installation. It allows to generate barcode from all barcode types supported. Please note that - since the requirements on length and characters changes from type to type - sometimes error messages are displayed; in this case, click on the "Sample text" button to use a predefined sample text for the selected barcode type. A screenshot is displayed at the top of this page.

225	180		## Final notes
226	181
227	182		If you need the generation of another barcode and it is present in Zint, please ask for it in the [Lazarus forum](http://forum.lazarus.freepascal.org/) or mailing lists.
