I have a .bmp image..I want to read the intensities of the pixels in a 2d array...how can i do that??plz help...
Here's an example program that displays the data for a 24-bit bitmap. (It will not work for bitmaps with a color palette.) Code: #include <stdio.h> #include <windows.h> int main() { BITMAPFILEHEADER bmfh; BITMAPINFOHEADER bmih; RGBTRIPLE rgbt; FILE *f; int i; f = fopen ("test.bmp", "rb"); printf ("File Header\n"); fread (&bmfh, sizeof(bmfh), 1, f); printf (" Size : %u\n", bmfh.bfSize); printf (" OffBits : %u\n", bmfh.bfOffBits); printf ("Info Header\n"); fread (&bmih, sizeof(bmih), 1, f); printf (" Size : %u\n", bmih.biSize); printf (" Width : %u\n", bmih.biWidth); printf (" Height : %u\n", bmih.biHeight); printf (" Planes : %u\n", bmih.biPlanes); printf (" BitCount : %u\n", bmih.biBitCount); printf (" SizeImage: %u\n", bmih.biSizeImage); printf (" ClrUsed : %u\n", bmih.biClrUsed); printf ("RGB Triples\n"); for (i = 0; i < bmih.biWidth * bmih.biHeight; ++i) { fread (&rgbt, sizeof(rgbt), 1, f); printf ("%02x %02x %02x\n", rgbt.rgbtRed, rgbt.rgbtGreen, rgbt.rgbtBlue); } fclose (f); return 0; }
