/*
* 参数说明
tpImage 输入图像，可使用”eyemImageRead“接口读取图片（需与“eyemImageFree”配合使用），也可直接创建EyemImage对象。
tpRoi 感兴趣区域，尺寸不能小于iSymbolMax。
fileName 文件名，可不填。
strCodeType 所要识别条码类型，“QRCode|DataMatrix|CODE_128”等等。
hObject 结果释放句柄，配合eyemDetectAndDecodeFree使用
tpResults 识别结果
ipNum 结果数量
bUseNiBlack 使用NiBlack二值化，默认值 false。
iBlockSize 定位块大小（奇数），略大于最大定位块（只二维码），佳世达一般设置为11。
iRangeC 搜索范围，范围越大识别越好时间也相应越长，佳世达一般设置为5。
iSymbolMin 最小二维码尺寸，默认128。
iSymbolMax 最大二维码尺寸，佳世达一般设置为215。
dScaleUpAndDown 缩放，<1表示缩小，>1表示放大，=1表示不缩放
dToleErr 最大允许误差默认50%，越小越严格但可能会识别不到。
dMinorStep 步进，默认1.0。
//返回值
-3 图像不存在
-1 内存不足
0 正常
-100 未识别到条码或参数设置不正确
