| Name | Type | Description |
|---|---|---|
| cbSize | DWORD | Specifies the length, in bytes, of the structure. |
| uFlags | UINT | A set of bit flags you can use to initialize the dialog box. |
| hIGear | HIGEAR | A handle of an image. |
| hWnd | HWND | A handle of the window to update. |
| lpszTitle | LPCHAR | A dialog title. |
| rc | AT_RECT | An AT_RECT struct specifying the rectangular portion of the image to be processed. |
| nExtent | UINT | Set to a UINT for the amount of motion you would like applied. If nCompassDir is set to "S, W, E, N", the correct range for this variable is 2 - 17. If nCompassDir is set to "SE, NE, NW, SW", the correct range for this variable is 3 - 22. This variable determines the extent to which the pixels will be "moved" or "smeared." It is the number of pixel lengths to be "moved over". |
| nCompassDir | AT_MODE | An AT_MODE constant such as IG_COMPASS_N or IG_COMPASS_SE. |
| nErrCount | AT_ERRCOUNT | The number of ImageGear errors that occurred during this function call. |
| lpfnUpdateProc | LPFNIGGUI_FX_UPDATE | A pointer to the function that is called when the 'Apply' button is clicked. |
