DeformationResistingModes

DeformationResistingModes is a parameter to control how to handle distorted and deformed barcodes. It consisits of one or more modes, each mode represents a way to implement the deformation resisting.

Candidate Mode List

  • DRM_GENERAL
  • DRM_BROAD_WARP
  • DRM_LOCAL_REFERENCE
  • DRM_DEWRINKLE
  • DRM_AUTO

DRM_GENERAL

Resists deformation using the general algorithm. This mode has the following arguments for further customizing.

DRM_BROAD_WARP

Resists deformation when the barcode is warped gently.

DRM_LOCAL_REFERENCE

Resists deformation for barcodes with minor deformation in local modules.

DRM_DEWRINKLE

Resists deformation for barcodes on a wrinkled surface.

DRM_AUTO

Lets the library choose a mode automatically. Not supported yet.

Setting Methods

As PublicRuntimeSettings Member

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

Code Snippet in C++

//...other codes
PublicRuntimeSettings* pSettings = new PublicRuntimeSettings;
int errorCode = reader->GetRuntimeSettings(pSettings);
pSettings->deformationResistingModes[0] = DRM_GENERAL;
reader->UpdateRuntimeSettings(pSettings);
reader->SetModeArgument("DeformationResistingModes", 0, "Level", "1");
delete pSettings;
//...other codes

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

As JSON Parameter

DeformationResistingModes 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 deformation resisting.
Level A number from value range of Level (Optional) Sets the Argument Level.
LibraryFileName A string from value range of LibraryFileName (Optional) Sets the Argument LibraryFileName.
LibraryParameters A string from value range of LibraryFileName (Optional) Sets the Argument LibraryFileName.

JSON Parameter Example

{
    "DeformationResistingModes": [
        {
            "Mode": "DRM_GENERAL", 
            "Level": 1
        },
        {
            "Mode": "DRM_DEWRINKLE"
        }
    ]
}

Candidate Argument List

Level

Sets the effort level used for deformation resisting. Not supported yet.

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

Performance Adaptability
A larger value may improve the Read Rate but slowdown the Speed.

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
