Calculates the barcode size that is going to be written.
Syntax
Parameters
- dpiX
- The X-axis (along width) resolution of the RasterImage of the barcode being written.
- dpiY
- The Y-axis (along height) resolution of the RasterImage of the barcode being written.
- data
- BarcodeData class that contains the barcode information to be written on the image.
- codeColor
- BarcodeColor class that contains the color information to be written on the image.
- flags
-
Flags that indicate the method behavior. Values can be combined when appropriate, by using a bitwise OR (|).
Pass BarcodeWriteFlags.None to use the default values, based on the type of barcode that has been written.
- code1d
- Barcode1d class that contains the information about linear barcodes.
- codePdf
- BarcodeWritePdf class that contains the information about PDF417 and MicroPDF417 barcodes.
- codeDatamatrix
- BarcodeWriteDatamatrix class that contains the information about Data Matrix barcodes.
- codeQr
- BarcodeWriteQr class that contains the information about QR barcodes.
Return Value
Rectangle with the barcode size before writing the barcode over the image.
