拜託幫幫忙囉

我真的很急

就是讀入一張影像檔

然後要把影像檔分成四塊

1 2

3 4

向上面這種格式

並且要讀出每個區塊左上級右下角的座標

拜託大家教教我~~~

我已經會讀入檔案了

所以只剩下要怎麼分塊呀???

   Graphics::TBitmap *bmpSrc=new Graphics::TBitmap;
Graphics::TBitmap *bmpDst=new Graphics::TBitmap;
bmpSrc->LoadFromFile("原圖.bmp");
bmpDst->Width=80; //切割後小區塊的大小
bmpDst->Height=60;

SetStretchBltMode(bmpDst->Canvas->Handle, STRETCH_HALFTONE);
bmpDst->Canvas->CopyMode=cmSrcCopy;
bmpDst->Canvas->CopyMode=cmSrcCopy;

bmpDst->Canvas->CopyRect(Rect(0, 0, 80, 60), bmpSrc->Canvas,Rect(0, 0, 80, 60)); //設定左上圖大小為80X60，是將原圖中切割出x軸0到80，y軸0到60
bmpDst->SaveToFile("左上.bmp");

bmpDst->Canvas->CopyRect(Rect(0, 0, 80, 60), bmpSrc->Canvas,Rect(80, 0, 160, 60)); //設定右上圖大小為80X60，是將原圖中切割出x軸80到160，y軸0到60
bmpDst->SaveToFile("右上.bmp");
bmpDst->Canvas->CopyRect(Rect(0, 0, 80, 60), bmpSrc->Canvas,Rect(0, 60, 80, 120)); //設定左下圖大小為80X60，是將原圖中切割出x軸0到80，y軸60到120
bmpDst->SaveToFile("左下.bmp");
bmpDst->Canvas->CopyRect(Rect(0, 0, 80, 60), bmpSrc->Canvas,Rect(80, 60, 160, 120)); //設定右上圖大小為80X60，是將原圖中切割出x軸80到160，y軸60到120
bmpDst->SaveToFile("右下.bmp");

delete bmpDst;
delete bmpSrc;
Image2->Picture->LoadFromFile("左上.bmp");
Image3->Picture->LoadFromFile("右上.bmp");
Image4->Picture->LoadFromFile("左下.bmp");
Image5->Picture->LoadFromFile("右下.bmp");
這個段程式有個限制就是每一個切割後的小區塊是同等大小的哦~
