API Reference Guide > GUI Component API Reference > GUI Component Functions Reference > Image Processing Functions > IG_gui_ip_gaussian_blur_dlg

This function shows the dialog that allows you to choose parameters and apply the Gaussian Blur transform.

Declaration:

 
Copy Code
BOOL ACCUAPI IG_gui_ip_gaussian_blur_dlg (
        HWND hWnd, 
        LPAT_IGGUI_IP_GAUSSIAN_BLUR lpIpGaussianBlurData
);

Arguments:

Name Type Description
hWnd HWND A handle of the parent window.
lpIpGaussianBlurData LPAT_IGGUI_IP_GAUSSIAN_BLUR A pointer to the AT_IGGUI_IP_GAUSSIAN_BLUR structure.

Return Value:

If the user specifies parameters and clicks the OK button, the return value is non-zero. If the user cancels or closes the dialog box or an error occurs, the return value is zero.

Supported Raster Image Formats:

All pixel formats supported by ImageGear for C and C++, except:
Indexed RGB with non-grayscale palette.

Sample:

Image Processing

Example:

 
Copy Code
#include "IG_gui_common.h"
AT_IGGUI_IP_GAUSSIAN_BLUR IpGaussianBlur;
IpGaussianBlur.cbSize = sizeof (IpGaussianBlur);
IpGaussianBlur.hWnd = hWnd;
IpGaussianBlur.hIGear = hIGear;
IpGaussianBlur.uFlags |= IG_IGGUI_IP_SETUP_EMPTY_RECT;
IpGaussianBlur.dblRadius = 1.0;
if (IG_gui_ip_gaussian_blur_dlg (hWnd, &IpGaussianBlur))
{
InvalidateRect(hWnd, NULL, FALSE);
        UpdateWindow(hWnd);
}

Remarks:

The Gaussian Blur transform makes images look softer and slightly out of focus. A specific feature of Gaussian Blur is that it removes the high-frequency component from the image.
