我已翻過不少"scanline"和"bitmap"的文章
但一直沒看到將unsigned char的原始影像格式轉成bitmap的格式,因為我想畫在Timage上面.
請問大大站上有沒相關的範例?

我的程式碼

[code cpp]
#define W 300
#define H 200
Ipp8u *pBuf0 = ippiMalloc_8u_C1(W,H,&step0); // create buffer0,型別unsigned char,非bcb函式
ippiImageJaehne_8u_C1R(pBuf0, step0, roiSize); // fill buffer0 with Jaehne test image,非bcb函式
Graphics::TBitmap *pBitmap = new Graphics::TBitmap(); //VCL class must be structed by "new"
pBitmap->PixelFormat=pf8bit;
pBitmap->Width=W;
pBitmap->Height=H;
Byte *ptr1;
k=0;
for(int i = 0; i < H; i )
{
for(int j = 0; j < W; j )
{ ptr1=(Byte*) pBitmap->ScanLine[H];
ptr1[i]=pBuf1[k =i];
}
}
Image->Canvas->Draw(0,0,ptr1); //程式掛在這行
[/code]

錯誤訊息
[C Error] Unit1.cpp(55): E2034 Cannot convert 'unsigned char *' to 'TGraphic *'
[C Error] Unit1.cpp(55): E2342 Type mismatch in parameter 'Graphic' (wanted 'TGraphic *', got 'unsigned char *')

改成
Image->Canvas->Draw(0, 0, pBitmap);

感謝!!
我果然對指標概念還很薄弱..
都忘了*ptr指到TBitmap上了
