thank you very much for replying.

first of all read the bitmap information.. it contains header info after that only data gets start.. so tats only i have separated the header info after that read the data info .....

what i understand from this is:

i need to make a: bitmap file header like this one:

typedef struct {

unsigned short int type; /* Magic identifier */

unsigned int size; /* File size in bytes */

unsigned short int reserved1, reserved2;

unsigned int offset; /* Offset to image data, bytes */

} HEADER;

and a bitmap info header like this one:

typedef struct {

unsigned int size; /* Header size in bytes */

int width,height; /* Width and height of image */

unsigned short int planes; /* Number of colour planes */

unsigned short int bits; /* Bits per pixel */

unsigned int compression; /* Compression type */

unsigned int imagesize; /* Image size in bytes */

int xresolution,yresolution; /* Pixels per meter */

unsigned int ncolours; /* Number of colours */

unsigned int importantcolours; /* Important colours */

} INFOHEADER;

should i also give the values for type, size, offset, reserved, width, height, etc. or just this?

and i am going to include this header file to my sd card source file?

about the "header=(unsigned char)(alt_up_sd_card_read(sd_fileh));", where did you get the name 'header'? sorry, i'm not really familiar with c so i'm having a hard time with programming in nios but i need to make this work for our project. thanks for the help.
