This function shows the dialog that allows you to reduce the number of bits per pixel for the original image using different methods.

Declaration:

BOOL ACCUAPI IG_gui_ip_color_reduce_dlg (
        HWND hWnd, 
        LPAT_IGGUI_IP_COLOR_REDUCE lpIpColorReduceData
);

Arguments:

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:

Depending on the reduction options:

• Bayer, Diffuse, Half tone, Bitonal:
  Indexed RGB – 4, 8 bpp;
  Grayscale – 4, 8 bpp;
  RGB – 24 bpp.
• Median Cut, Octree, Popularity:
  Indexed RGB – 8 bpp;
  Grayscale – 8 bpp;
  RGB – 24 bpp.

Example:

#include "IG_gui_common.h"
AT_IGGUI_IP_COLOR_REDUCE IpColorReduce;
IpColorReduce.cbSize = sizeof (IpColorReduce);
IpColorReduce.hWnd = hWnd;
IpColorReduce.hIGear = hIGear;
IpColorReduce.nReduceType = IG_IGGUI_IP_COLOR_REDUCE_BAYER;
if (IG_gui_ip_color_reduce_dlg (hWnd, &IpColorReduce))
{
InvalidateRect(hWnd, NULL, FALSE);
        UpdateWindow(hWnd);
}
