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 image to be processed. |
nType | WORD | An IG_NOISE constant such as IG_NOISE_LINEAR, IG_NOISE_GAUSSIAN. |
dblStrength | DOUBLE | From 0.0 to 127.0, specifying the degree of noise alteration to introduce into affected pixels. |
nHitRate | INT | Set = 1 to add noise to all pixels, > 1 to skip pixels, only adding noise to some. Larger values cause fewer pixels to be affected. Valid range is from 1 to 500. |
dblSigma | DOUBLE | Used with IG_NOISE_GAUSSIAN; the valid range is from 0.1 to 25.0. |
nColorChannel | AT_MODE | An IG_COLOR_COMP_ constant. See file accucnst.h for a complete list. |
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. |
