    IG_gui_ip_gaussian_blur_dlg
    In This Topic

    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.
