The method returns the actual size of a rotated barcode symbol that is specified by parameters of this method, in millimeter.
Note, if the Display field of BarcodeTextDefine parameter isn't set to dtNone, pelase use the method between Printer.BeginDoc and Printer.EndDoc methods, and the printer must be connected to your computer.
TotalWidth: Double; Returns the horizontal width of the rotated barcode symbol in millimeters.
Before rotation, if the human readable text is represented, both the width of human readable text and the height of the human readable text (including its vertical spacing) will be consulted. Otherwise, they will not be consulted. Note, if the human readable text is represented and it exceeds the barcode symbol in horizontal or vertical direction, the excess is included.

See also the "Height" property.
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. For Delphi/C++ Builder 2009 or later, it is in fact an UnicodeString instead of AnsiString.
For the TBarcode1D_Code128 and the TBarcode1D_EAN128 components, if you use them in the Delphi/C++ Builder 2007 or early, the Barcode parameter is in fact an AnsiSting in ANSI encoding scheme. 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 paramater. Also, you can use the method if you encode a block of binary (bytes) data; If you use them in the 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 PrintSize (Syntax 3) overloading method and specify the converted string in its Data paramater. If you encode a block of binary (bytes) data, please use the PrintSize (Syntax 3) overloading method. Note, the "\" character is used as a escape prefix, so if you want to encode the "\" character, please use the "\\" instead of it.
For the TBarcode1D_OneCode component, first 20 characters are the Tracking (It is right padded with zeroes to 20 characters), then come the Routing.
For the TBarcode1D_FIM component, it is single character that denotes the FIM type, form "A" to "E", the "E" character dnotes an empty barcode symbol.
For the TBarcode1D_Patch component, it is single character that denotes the Ptach type, and it can be set to "0", "1", "2", "3", "4", "6", and "T", the "0" character dnotes an empty barcode symbol.
For the TBarcode1D_Code32 component, First "A" character does not need to be entered in the parameter. Also, for the TBarcode1D_PZN component, First "PZN" characters do not need to be entered in the parameter.
See also the "Barcode" property.
AutoCheckDigit: Boolean; Specifies whether the check digit should be automatically appended to the barcode symbol.
See also the "AutoCheckDigit" property.
BarcodeTextDefine: TBarcodeTextDefine; Specifies whether to display the human readable text and how to display the human readable text. The record is defined in the pBarcode1D unit.
See also the TBarcodeTextDefine record.
Ratio: Double; Specifies ratio between a wide bar (or space) and a narrow bar (or space) in the barcode symbol. The normal values are from 2.0 to 3.0. If the parameter is less than or equal to zero, the method fails, and the return value is -2.
See also the "Ratio" property.
Module: Double; Specifies the module width in millimeters, it is the width of the smallest bar (or space) in the barcode symbol.
If the BarcodeWidth parameter is greater than zero, the value in the Module will be ignored, the module value will be calculated based on the BarcodeWidth parameter. If both Module and BarcodeWidth parameters are less than or equal to zero, the BarcodeHeight parameter must be set to greater than zero, the module value will be calculated based on the BarcodeHeight parameter and the Height property.
See also the "Module" property.
BarcodeWidth: Double, Specifies the barcode symbol width before rotation, in millimeters. If the human readable text is displayed and it exceeds the barcode symbol in horizontal direction, the excess isn't included in the width value.
For TBarcode1D_UPCA, TBarcode1D_UPCE, TBarcode1D_UPCE0, TBarcode1D_UPCE1, TBarcode1D_EAN2, TBarcode1D_EAN5, TBarcode1D_EAN8, and TBarcode1D_EAN13 barcode components, if the human readable text is displayed, and the TextAlignment field of the BarcodeTextDefine parameter is set to taCustom, the width of quiet zone marks and their horizontal spacing (LeftQuietZoneSpacing and RightQuietZoneSpacing) are included.
For TBarcode1D_ITF6, TBarcode1D_ITF14, and TBarcode1D_ITF16 barcode components, width of left and right bearer bars (BearerWidth), left spacing, and right spacing are included too.
If the parameter is provided and isn't zero; the value in Module parameter will be ignored, the module width will be calculated based on the BarcodeWidth value. If the parameter isn't provided or it's set to zero, the Module parameter will be used.
See also the "BarcodeWidth" property.
BarcodeHeight: Integer; Specifies the distance between the top and bottom of the barcode symbol before rotation, in millimeters or modules. If the human readable text is displayed, the height of the human readable text and its vertical spacing (TextVSpacing) are included. If it exceeds the barcode symbol in vertical direction, the excess isn't included.
For TBarcode1D_ITF6, TBarcode1D_ITF14, and TBarcode1D_ITF16 barcode components, the height of top and bottom bearer bars are included too.
If the parameter isn't provided or it's set to zero, it will be calculated based on the values of Module parameter and the Height property.
If the parameter is provided and it is not set to zero, the value of Height property will be ignored. If it's greater than zero, it specifies the height in millimeters. If it's less than zero, the absolute value of the parameter specifies the height in modules.
Angle: Integer; Specifies an angle in degrees to rotate the barcode symbol. It defaults to 0 if the Angle is not provided, meaning left to right horizontal direction.
HDPI: Integer, Specifies the physical horizontal resolution of printer in DPI (dots per inch).
It defaults to 0 if the HDPI is not provided. If it is set to less than or equal to zero, the horizontal resolution will be obtained from your printer.
VDPI: Integer, Specifies the physical vertical resolution of printer in DPI (dots per inch).
It defaults to 0 if the VDPI is not provided. If it is set to less than or equal to zero, the vertical resolution will be obtained from your printer.
See diagram:
For Delphi 3, the method overload and default value of parameter aren't supported, so the method name is changed to PrintSize2, and the parameters Module, BarcodeWidth, BarcodeHeight, Angle, HDPI, and VDPI are required.
