L_VecDlgCamera

Summary

Brings up the Vector Camera dialog.

Syntax

L_LVDLG_API L_INT L_VecDlgCamera(hWnd, pVector, pCamera, dwFlags, pfnCallback, pUserData)

Parameters

L_HWND hWnd

Handle of the window that owns the dialog.

pVECTORHANDLE pVector

Pointer to the vector handle that references the vector image to be affected by the camera values.

pVECTORCAMERA pCamera

Pointer to a VECTORCAMERA structure that contains camera values. The values present in pCamera when the function is called are used to initialize the dialog. If this parameter is NULL when the function is called, the values used to initialize the dialog will come from the vector handle. When this function returns, this parameter is updated with the values entered through the dialog.

L_UINT32 dwFlags

User interface flags that determine the layout and action of the dialog. Possible values are:

LVCOMMDLGHELPCB pfnCallback

Pointer to an optional help callback function.

If you do not wish to provide help to this dialog, use NULL as the value of this parameter. To provide help to this dialog, use the function pointer as the value of this parameter. The callback function must adhere to the prototype described in LVCOMMDLGHELPCB.

L_VOID * pUserData

Void pointer that you can use to pass one or more additional parameters that the callback function needs.

To use this feature, assign a value to a variable or create a structure that contains as many fields as you need. Then, in this parameter, pass the address of the variable or structure, casting it to L_VOID *. The callback function, which receives the address in its own pUserData parameter, can cast it to a pointer of the appropriate data type to access your variable or structure. If the additional parameters are not needed, you can pass NULL in this parameter.

Example

This example will run the common camera dialog.

L_INT VecDlgCameraExample( 
   HWND hWnd, 
   pVECTORHANDLE pVector) 
{ 
   L_INT nRet; 
   VECTORCAMERA Camera; 
 
   nRet = L_VecGetCamera (pVector, &Camera); 
   if(nRet != SUCCESS) 
      return nRet; 
 
   nRet = L_VecDlgCamera ( 
      hWnd, 
      pVector, 
      &Camera, 
      VECTOR_DLG_AUTO_PROCESS | 
      VECTOR_DLG_SHOW_PREVIEW , 
      NULL, 
      NULL );
