TextureDetectionModes

TextureDetectionModes determines how to detect texture on an image. It consists of one or more modes, each mode represents a way to implement the detection.

Candidate Mode List

  • TDM_GENERAL_WIDTH_CONCENTRATION

TDM_GENERAL_WIDTH_CONCENTRATION

Detects texture using the general algorithm. This mode has the following arguments for further customizing.

Setting Methods

As PublicRuntimeSettings Member

TextureDetectionModes can be set dynamically during runtime as a member of FurtherModes, which is a member of PublicRuntimeSettings struct, it is an array with 8 TextureDetectionMode Enumeration items.

Code Snippet in C++

//...other codes
PublicRuntimeSettings* pSettings = new PublicRuntimeSettings;
int errorCode = reader->GetRuntimeSettings(pSettings);
pSettings->textureDetectionModes[0] = TDM_GENERAL_WIDTH_CONCENTRATION;
reader->UpdateRuntimeSettings(pSettings);
reader->SetModeArgument("TextureDetectionModes", 0, "Sensitivity", "5");
delete pSettings;
//...other codes

Remarks
GetModeArgument and SetModeArgument need to be called for getting and setting Arguments.

As JSON Parameter

TextureDetectionModes as a JSON parameter is a JSON Object array. Each JSON object is defined as below.

Key Name Key Value Description
Mode Any one in Candidate Mode List as string (Required) Specifies a mode for text filtering.
Sensitivity A number from value range of Sensitivity (Optional) Sets the Argument Sensitivity.
LibraryFileName A string from value range of LibraryFileName (Optional) Sets the Argument LibraryFileName.
LibraryParameters A string from value range of LibraryParameters (Optional) Sets the Argument LibraryParameters.

JSON Parameter Example

{
    "TextureDetectionModes": [
        {
            "Mode": "TDM_GENERAL_WIDTH_CONCENTRATION", 
            "Sensitivity": 5
        }
    ]
}

Candidate Argument List

Sensitivity

Sets the sensitivity used for texture detection.

Value Type Value Range Default Value Valid For
int [1, 9] 5 TDM_GENERAL_WIDTH_CONCENTRATION

Remarks
A larger value means the library will take more effort to detect texture.

LibraryFileName

Sets the file name of the library to load dynamically.

Value Type Value Range Default Value Valid For
string A string value representing file name. ”” All modes

Remarks
The library must be in the same place with Dynamsoft Barcode Reader Library.

LibraryParameters

Sets the parameters passed to the library to load dynamically.

Value Type Value Range Default Value Valid For
string A string value representing parameters. ”” All modes
