Ex9 處理BMP圖檔的C++程式(未用任何library)
要處理的511x511未壓縮tiffany bmp圖檔,
作業為產生R、G、B、半灰半彩的圖檔
0)class ImageMarix:
1)使用windows.h中的
struct BITMAPFILEHEADER
2)使用windows.h中的
struct BITMAPINFOHEADER
3)class ImageMarix 中的變數成員與建構子,注意rowsize必須是4的倍數,一個pixel有3 bytes RGB的顏色,不足4的倍數,往上padding。
4)透過seekg移動游標至檔尾,透過tellg來告知圖檔實際大小,透個read來讀取表頭、圖檔資料表圖、像素資料。像素的排列順序是GBR,先由左而右、再下而上,與座標再下而上,與座標不同,也與矩陣排列不同。
5)透個write來寫表頭、圖檔資料表圖、像素資料
6)簡易的轉灰階函數convert2gray,像素的排列順序是GBR,公式為
gray=(BYTE)(0.2989*R + 0.5870*G + 0.1140*B+0.5)
更一般的版本。自訂windows常用的BITMAPFILEHEADER、BITMAPINFOHEADER,
可在windows、linux上執行。要加上前置處理器,對齊struct, class中成員,如
#pragma pack(push)
#pragma pack(2)
....
#pragma pack(pop)
