Example 4-9 Converting a DIB Image Into an IplImage (continued)

dibh->biCompression = BI_RGB;

dibh->biSizeImage = size;

dibh->biClrUsed = 256;

dibh->biClrImportant = 0;

// fill in colors of the bitmap

for( i=0; i<256; i++)

rgb[i].rgbBlue = rgb[i].rgbGreen = rgb[i].rgbRed=

(unsigned char)i;

// set the bitmap data

for( i=0; i<WIDTH*HEIGHT; i++)

data[i] = (unsigned char)(100 + i);

// create header of the desired image

img = iplCreateImageHeader( 1,0, IPL_DEPTH_16U,

"GRAY", "GRAY", IPL_DATA_ORDER_PIXEL,

IPL_ORIGIN_BL, // bottom left as in DIB

IPL_ALIGN_QWORD, WIDTH, HEIGHT, NULL, NULL, NULL,

NULL);

if( NULL == img ) return 0;

// create ipl image converting 8u to 16u

iplConvertFromDIB ( dibh, img );

if( !img->imageData ) return 0;

}

__finally {

if( dib ) free( dib );

iplDeallocate(img,IPL_IMAGE_HEADER|IPL_IMAGE_DATA);

}

return IPL_StsOk == iplGetErrStatus();

}

As necessary, the conversion result is saturated.
