RESULT | [OUT] EplHandle |
After execution of the command, this parameter can be used to query the handle of the created circle object. |
The eplExecuteCommand function returns EPL_OK if the circle could be successfully inserted into the page.
If the command fails, eplExecuteCommand returns the value EPL_ERROR. In this case, the error log can contain the following errors:
ErrorID | Description |
---|---|
EPL_ERR_NO_RIGHT | The current user group is not allowed to modify the page. |
EPL_ERR_FAILED | The circle could not be created. |
EPL_ERR_INVALID_ARGUMENT | The PAGE parameter is not an object of the Page type. |
The following example shows a function which inserts a circle into a page. The handle to the page object must be determined first.
EplHandle createCircle(EplSession s, EplHandle page) { EplHandle hRet(EPL_ERROR); //Create command EplHandle cmdCreateCircle = eplCreateCommand(s, L"EPLAN.EPLAN21.CIRCLE.CREATE"); if(cmdCreateCircle != EPL_ERROR) { //Set parameters // //Page handle eplSetHandleParam(s, cmdCreateCircle, EPL_PARAM_GRAPHIC_CREATE_PAGE, page, 0); //Pen size eplSetParam(s, cmdCreateCircle, EPL_PARAM_GRAPHIC_CREATE_PENWIDTH, L"1", 0); //Pen color eplSetParam(s, cmdCreateCircle, EPL_PARAM_GRAPHIC_CREATE_COLOR, L"7", 0); //X/Y coordinates of circle center eplSetParam(s, cmdCreateCircle, EPL_PARAM_GRAPHIC_CREATE_XPOS, L"100000", 0); eplSetParam(s, cmdCreateCircle, EPL_PARAM_GRAPHIC_CREATE_YPOS, L"100000", 0); //Radius eplSetParam(s, cmdCreateCircle, EPL_PARAM_GRAPHIC_CREATE_DELTA_X, L"10000", 0); //Execute command if(eplExecuteCommand(s, cmdCreateCircle) = EPL_OK) { // Query result: hRet = eplGetHandleParam(s, cmdCreateCircle, EPL_PARAM_GRAPHIC_CREATE_RESULT, 0); } eplCloseObject(s, cmdCreateCircle); } return hRet; } |
