for(x=0;x<54;x++){

header=(unsigned char)(alt_up_sd_card_read(sd_fileh));

}

this will read the header info of bitmap file..then read the bgr info of bitmap ... (RGB value is stored in reverse).. tats only i used for to read bgr.. the bitmap file is 24 bit format... i have used pixels value converted into 16 bit format... i have tried for 24 bit also but not getting the exact ouptut..while using 16bit means it shows the exact output on VGA...
