Normalize |
Normalizes the source image. |
DetectQuad
Detects quad from source image.
int dynamsoft::ddn::CDocumentNormalizer::DetectQuad(const char* sourceFilePath, const char* templateName, CDetectedQuadResultArray** result)
int dynamsoft::ddn::CDocumentNormalizer::DetectQuad(const CImageData* sourceImage, const char* templateName, CDetectedQuadResultArray** result)
Parameters
[in] sourceFilePath A string defining the source file path. It supports BMP, JPEG, PNG, TIFF and PDF files.
[in] sourceImage The source image buffer.
[in] templateName The template name. A template name is the value of key ImageParameter.Name defined in JSON formatted settings. If no template name is specified, current runtime settings will be used.
[out] result An array of all detected quad results. It is allocated by the SDK and should be freed by calling function FreeDetectedQuadResultArray.
Return Value
Returns error code (returns 0 if the function operates successfully).
You can call DC_GetErrorString to get detailed error message.
Code Snippet
int errorCode = 0;
char szErrorMsg[256];
errorCode = CLicenseManager::InitLicense("YOUR-LICENSE-KEY", szErrorMsg, 256);
//...handle the errorCode
CDocumentNormalizer ddn;
CDetectedQuadResultArray* detectedQuadResultArray = NULL;
errorCode = ddn.DetectQuad("YOUR-SOURCE-FILE-PATH", "", &detectedQuadResultArray);
//generate imageData from somewhere else
//errorCode = ddn.DetectQuad(imageData, "", &detectedQuadResultArray);
//...do something with the detectedQuadResultArray and errorCode
CDocumentNormalizer::FreeDetectedQuadResultArray(&detectedQuadResultArray);
Normalize
Normalizes the source image.
int dynamsoft::ddn::CDocumentNormalizer::Normalize(const char* sourceFilePath, const char* templateName, const CQuadrilateral* quad, CNormalizedImageResult** result)
int dynamsoft::ddn::CDocumentNormalizer::Normalize( const CImageData* sourceImage, const char* templateName, const CQuadrilateral* quad, CNormalizedImageResult ** result)
Parameters
[in] sourceFilePath A string defining the source file path. It supports BMP, JPEG, PNG, TIFF and PDF files.
[in] sourceImage The source image buffer.
[in] templateName The template name. A template name is the value of key ImageParameter.Name defined in JSON formatted settings. If no template name is specified, current runtime settings will be used.
[in] quad The quadrilateral representing the boundary of the content to be normalized.
[out] result The normalized image result. It is allocated by the SDK and should be freed by calling function FreeNormalizedImageResult.
Return Value
Returns error code (returns 0 if the function operates successfully).
You can call DC_GetErrorString to get detailed error message.
