DecodeFile

Decode barcodes from a specified image file.

TextResult[] Dynamsoft.DBR.BarcodeReader.DecodeFile(string fileName, string templateName)

Parameters
[in] fileName <string> : A string defining the file name. It supports BMP, JPEG, PNG, TIFF and PDF files.
[in] templateName <string> : The template name.

Return Value
TextResult array.

Exception
BarcodeReaderException The exception thrown by Dynamsoft Barcode Reader.

Code Snippet

string errorMsg;
BarcodeReader.InitLicense("YOUR-LICENSE-KEY", out errorMsg);
BarcodeReader reader = BarcodeReader.GetInstance();
if (reader != null)
{
	TextResult[] result = reader.DecodeFile(@"C:\Program Files (x86)\Dynamsoft\{Version number}\Images\AllSupportedBarcodeTypes.tif", "");
	//... add further process
    reader.Recycle();
}

DecodeFileInMemory

Decode barcodes from an image file in memory.

TextResult[] Dynamsoft.DBR.BarcodeReader.DecodeFileInMemory(byte[] fileStream, string templateName)  

Parameters
[in] fileStream <byte[]> : The image file bytes in memory.
[in] templateName <string> : The template name.

Return Value
TextResult array.

Exception
BarcodeReaderException The exception thrown by Dynamsoft Barcode Reader.

Code Snippet

string errorMsg;
BarcodeReader.InitLicense("YOUR-LICENSE-KEY", out errorMsg);
BarcodeReader reader = BarcodeReader.GetInstance();
if (reader != null)
{
	byte[] fileStream = GetFileStream(@"C:\Program Files (x86)\Dynamsoft\{Version number}\Images\AllSupportedBarcodeTypes.tif");
	TextResult[] result = reader.DecodeFileInMemory(fileStream, "");
	//... add further process
    reader.Recycle();
}

DecodeBuffer

Decode barcodes from the memory buffer containing image pixels in a defined format.

TextResult[] Dynamsoft.DBR.BarcodeReader.DecodeBuffer(byte[] buffer, int width, int height, int stride, EnumImagePixelFormat imagePixelFormat, string templateName)

TextResult[] Dynamsoft.DBR.BarcodeReader.DecodeBuffer(byte[] buffer, int width, int height, int stride, EnumImagePixelFormat imagePixelFormat, int orientation, string templateName)

Parameters
[in] buffer <byte[]> : The array of bytes which contain the image data.
[in] width <int> : The width of the image in pixels.
[in] height <int> : The height of the image in pixels.
[in] stride <int> : The stride of the image (also called scan width).
[in] imagePixelFormat <EnumImagePixelFormat> : The image pixel format used in the image byte array.
[in] orientation <int> : The orientation of the image data. The value is the angle that the image needs to be rotated clockwise so it shows correctly on the display in its natural orientation. It can be 0, 90, 180, or 270.
[in] templateName <string> : The template name.

Return Value
TextResult array.

Exception
BarcodeReaderException The exception thrown by Dynamsoft Barcode Reader.

Code Snippet

string errorMsg;
BarcodeReader.InitLicense("YOUR-LICENSE-KEY", out errorMsg);
BarcodeReader reader = BarcodeReader.GetInstance();
if (reader != null)
{
	Bitmap bBMP = new Bitmap(@"C:\Program Files (x86)\Dynamsoft\{Version number}\Images\AllSupportedBarcodeTypes.tif");
	BitmapData bmdat = bBMP.LockBits(new Rectangle(Point.Empty, bBMP.Size), ImageLockMode.ReadOnly, PixelFormat.Format32bppArgb);
	int width = bBMP.Width;
	int height = bBMP.Height;
	int stride = bmdat.Stride;
	byte[] buffer = new byte[stride * bmdat.Height];
	Marshal.Copy(bmdat.Scan0, buffer, 0, buffer.Length);
	bBMP.UnlockBits(bmdat);
	EnumImagePixelFormat imagePixelFormat = EnumImagePixelFormat.IPF_ARGB_8888;
	TextResult[] result = reader.DecodeBuffer(buffer, width, height, stride, imagePixelFormat, "");
	//TextResult[] result = reader.DecodeBuffer(buffer, width, height, stride, imagePixelFormat, 0, "");
	//... add further process
    reader.Recycle();
}

DecodeBase64String

Decode barcode from an image file encoded as a base64 string.

TextResult[] Dynamsoft.DBR.BarcodeReader.DecodeBase64String(string base64, string templateName)	

Parameters
[in] base64 <string> : A base64 encoded string that represents an image.

	TextResult[] result = reader.DecodeBase64String(base64String, "");
	//... add further process
    reader.Recycle();
