Barcode: String; Specifies the barcode text. It is of type string.
For Delphi/C++ Builder 2007 or early, the Barcode parameter is in fact an AnsiString. By default, it is an ANSI encoding string, if you want to use other encoding scheme (for example the UTF-8, UTF-16), please convert it in the OnEncode event, or specify the converted string in the Barcode parameter. Also you can use the method if you encode a block of binary (bytes) data.
For Delphi/C++ Builder 2009 or later, it is in fact an UnicodeString instead of AnsiString. By default, the unicode string will be converted to an ANSI encoding string, then be encoded into the barcode symbol. If you want to use other encoding scheme (for example the UTF-8, UTF-16), please convert it in the OnEncode event, or use the DrawToSize (Syntax 3) overloading method and specify the converted string in its Data parameter. If you encode a block of binary (bytes) data, please use the DrawToSize (Syntax 3) overloading method.
For the TBarcode2D_RSS14 and TBarcode2D_RSSLimited components, if the property AutoCheckDigit is set to true, the check digit doesn't need to be included in the parameter, otherwise the check digit can be specified by you in the parameter.

The parameter only specifies the barcode text for the 2D symbol, the barcode text of linear symbol is specified by the Barcode or Data (only for Delphi/C++ Builder 2009 or later) property of the linear component.
See also the "Barcode" and "Data" (only for Delphi/C++ Builder 2009 or later) properties.
ShowQuietZone: Boolean; Specifies whether to include the leading, trailing, top and bottom quiet zones in barcode symbol. If the parameter value is set to true, these quiet zones are included in the barcode symbol. Otherwise, they don't be included. You can use the LeadingQuietZone, TrailingQuietZone, TopQuietZone, and BottomQuietZone properties to specify the size of these quiet zones in modules. See diagram (the quiet zones are drawn in clSilver color in order to accentuate them):
For the TBarcode2D_Code16K barcode component, the leading quiet zone and the trailing quiet zone will be included always, even if the ShowQuietZone parameter value is set to false. See diagram (the quiet zones are drawn in clSilver color in order to accentuate them):
For the TBarcode2D_CCA, TBarcode2D_CCB, and TBarcode2D_CCC barcode components, if the Linear property is set, the 2D symbol and the linear symbol are assembled to generate an EAN.UCC composite barcode symbol. And the LeadingQuietZone, TrailingQuietZone, TopQuietZone, and BottomQuietZone properties specify the size of quiet zones for entire EAN.UCC composite symbol, they are not only for the 2D symbol. See diagram (the quiet zones are drawn in clSilver color in order to accentuate them):

Similarly, if its right quiet zone mark is represented (the TextAlignment property's value is set to taCustom, and for the TBarcode1D_ENA8 and TBarcode1D_EAN13 components, the ShowQuietZoneMark property is set to true too), the trailing quiet zone will be included even if the ShowQuietZone parameter is set to false, the minimum width of trailing quiet zone is the distance between the last bar of the 2D symbol and the right side of the right quiet zone mark of the linear symbol, and the minimum width of trailing quiet zone will be used if the value of TrailingQuietZone property is less than it. In other words, the leading and trailing quiet zoens will be automatically extanded to cover the left and right quiet zone marks, regardless of whether the ShowQuietZone parameter is set to true or false. See diagram (the quiet zones are drawn in clSilver color in order to accentuate them):
For all of the TBarcode2D_CCA, TBarcode2D_CCB, and TBarcode2D_CCC barcode components, if the linear component is the TBarcode1D_UPCE, TBarcode1D_UPCE0, TBarcode1D_UPCE1, TBarcode1D_UPCA, TBarcode1D_ENA8, TBarcode1D_EAN13, or TBarcode1D_EAN128, and its human readable text is represented and exceeds the beginning or end of entire EAN.UCC barcode symbol (the leading and trailing quiet zones are included if the ShowQuietZone parameter is set to true), the leading and trailing quiet zoens will be automatically extanded to cover the human readable text, regardless of whether the ShowQuietZone parameter is set to true or false. See diagram (the quiet zones are drawn in clSilver color in order to accentuate them):
See also the "ShowQuietZone" property.
Module: Integer; Specifies the module size in logical dots or pixels in the horizontal direction.
For the Matrix 2D barcode symbology (excluding the TBarcode2D_MaxiCode barcode symbology), the module is single cell (a suqare shape) used to encode one bit data. The parameter specifies the module width and height. See diagram:
For the TBarcode2D_MaxiCode barcode symbology, the module is single cell (a regular hexagonal shape) used to encode one bit data. The parameter specifies the horizonal width of a module. Also, it's the center to center horizontal distance between adjacent modules. See diagram:
For the Stacked 2D barcode symbology and Linear 1D barcode symbology, the module is the thinest bar (or space) in the barcode symbol. The parameter specifies the module width. See diagram:
For the 2D component TBarcode2D_CCA, TBarcode2D_CCB, or TBarcode2D_CCC, if its Linear property is set, the 2D symbol and the linear symbol are assembled to generate an EAN.UCC composite barcode symbol, the parameter specifies the module width for entire EAN.UCC composite barcode symbol (including both 2D and linear symbols). See diagram:
See also the "Module" property.
Angle: Integer; Specifies an angle in degrees to rotate the barcode symbol and its quiet zones (if they are represented, please read the ShowQuietZone parameter section above about whether or not the quiet zones will be represented) anticlockwise. You can use the LeadingQuietZone, TrailingQuietZone, TopQuietZone, and BottomQuietZone properties to specify the size of these quiet zones in modules. And use the ShowQuietZone parameter to specify whether to represent these quiet zones. See diagram (the quiet zones are drawn in clSilver color in order to accentuate them):
For the 2D component TBarcode2D_CCA, TBarcode2D_CCB, or TBarcode2D_CCC, if its Linear property is set, the 2D symbol and the linear symbol are assembled to generate an EAN.UCC composite barcode symbol, and they will be rotated as an entirety. See diagram (the quiet zones are drawn in clSilver color in order to accentuate them):
The parameter defaults to 0 if the Angle is not provided, meaning left to right horizontal direction.
Canvas: TCanvas; Specifies target canvas to represent the barcode symbol on it.
The parameter is useful only for the 2D component TBarcode2D_CCA, TBarcode2D_CCB, or TBarcode2D_CCC. If its Linear property is set to the TBarcode1D_UPCE, TBarcode1D_UPCE0, TBarcode1D_UPCE1, TBarcode1D_UPCA, TBarcode1D_ENA8, TBarcode1D_EAN13, or TBarcode1D_EAN128, and the linear component's DisplayText property isn't set to dtNone, the parameter is required in order to calculate the width of human readable text. Otherwise, it will be ignored, so you can set it to nil.
HDPI: Integer, Specifies the horizontal resolution of canvas in logical DPI. It's the number of logical dots or pixels per inch. It defaults to 0 if the HDPI is not provided, and the physical horizontal resolution obtained from the Canvas parameter will be used. So if you use the MM_TEXT map mode, you can specify it to 0. If you use the MM_ISOTROPIC or MM_ANISOTROPIC map mode, and the horizontal units or scaling is changed, the parameter is required in order to obtain the correct sizes when the symbol is rotated.
When the Canvas parameter is set to nil, if both HDPI and VDPI are set to 0, it indicates the horizontal resolution is equal to the vertical resolution.
VDPI: Integer, Specifies the vertical resolution of canvas in logical DPI. It's the number of logical dots or pixels per inch. It defaults to 0 if the VDPI is not provided, and the physical vertical resolution obtained from the Canvas parameter will be used. So if you use the MM_TEXT map mode, you can specify it to 0. If you use the MM_ISOTROPIC or MM_ANISOTROPIC map mode, and the vertical units or scaling is changed, the parameter is required in order to obtain the correct sizes when the symbol is rotated.
When the Canvas parameter is set to nil, if both HDPI and VDPI are set to 0, it indicates the horizontal resolution is equal to the vertical resolution.
