Brings up the Vector Camera dialog.
Parameter | Description | |
hWnd | Handle of the window that owns the dialog. | |
pVector | Pointer to the vector handle that references the vector image to be affected by the camera values. | |
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. | |
dwFlags | User interface flags that determine the layout and action of the dialog. Possible values are: | |
Value | Meaning | |
VECTOR_DLG_AUTO_PROCESS | [0x80000000] Process the image on OK. | |
VECTOR_DLG_SHOW_PREVIEW | [0x40000000] Show preview of image in dialog. | |
VECTOR_DLG_ENABLE_HELPBUTTON | [0x00000002] Enable Help button. | |
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. | ||
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. |
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
