[問題] 請問bmp圖檔
小弟想請問如何每次只讀取bmp檔裡的一個bit
以下是我讀檔的程式碼 可是應該只是把test.bmp複製過去test_bit.bmp而已
我該怎麼修改 謝謝！
ttt = 0;
row1 = width*3;(考慮RGB)
col1 = heigh;
if( ( rfp = fopen("test.bmp", "rb")) == NULL ||
( wfp = fopen("test_bit.bmp", "wb")) == NULL )
{
printf("Can not open file(s)! ");
return 0;
}
fread ( title, sizeof(char), 54, rfp );
fwrite( title, sizeof(char), 54, wfp );
fread( img, sizeof(char), heigh*width*3, rfp );
for( i = 0; i < heigh*width*3; i++ )
img1[i] = img[i];
fwrite( img1, sizeof(char), heigh*width*3, wfp );
fclose(wfp);
fclose(rfp);
