run

Description

Engine module execution API

run()

int run(void* obj, char** resultJson, char* openApiName, char* requestId, int imgWidth, int imgHeight, int colorSpace, char* imgData, char* requestOptionJsonStr)

Parameters

Name	Type	Description
obj	void*	'ArgoEngineApi' object pointer
resultJson	char**	Engine module execution result string (json)
openApiName	char*	Set name of engine module to use
requestId	char*	Request ID (value for request identification)
imgWidth	int	Image width
imgHeight	int	Image height
colorSpace	int	Image color type (RGB 0, RGBA 1, BGR 2, BGRA 3, YUV 4, GRAY 5)
imgData	char*	Image pixel data (byte array)
requestOptionJsonStr	char*	Json format string for setting options of engine module queried by getOpenApiOption

Return Value

int: Length of 'resultJson' string

Example

• Use OpenCV library
• Use sample 'ocr1.png'
• For runBase64 API, encode 'dataMat' to base64 and input for use

cv::Mat temp = cv::imread("ocr1.png", cv::IMREAD_COLOR);
std::string requestOptionJsonStr = “{}";
char *dataMat = (char *)temp.data;
char *resultJsonStr = nullptr;
int resultSize = run(obj,
&resultJsonStr,
(char *)openApiName.c_str(),
(char *)requestId.c_str(),
temp.cols,
temp.rows,
2,
dataMat,
(char *)requestOptionJsonStr.c_str());
std::string resultJson(resultJsonStr, resultSize);
