TranslateDIB Function

To convert a DIB image to the IplImage format, use the function iplTranslateDib(), as shown in this code example.

If the original DIB data for some reason could not be used in the IplImage, the function copies the image data and sets the variable clone to true. In this case, later you'll have to deallocate memory used for both IplImage data and the original DIB image data.

To run the example from the command line, type this command:
>create -t5 -fimages\g256.bmp
(-f specifies the image file name).

The source:

void create_translate_dib( const char* fname ) {
    BITMAPINFOHEADER* bmphdr = ipLoad( fname );
    if( bmphdr ) {
        int clone;
        IplImage* img = iplTranslateDIB( bmphdr, &clone );
        if( img ) {
            ipView( img, fname, is_modal );
            iplDeallocate( img, clone ? IPL_IMAGE_ALL : IPL_IMAGE_HEADER );
        }
        free( bmphdr );
    }
    else {
        TRACE0( "Problem reading the BMP file" );
    }
}

The ipLoad function used in this example can be found in the cookroom subdirectory of the tutorial.
