各位前輩你們好 小弟有個問題
就是我在細線化後的字 想要貼標籤作標籤化處裡!!
1.因為細線化後的字是黑的 我就寫了個掃描到黑色像素就給他標籤
但是RUN過後不是我想要的答案 已經弄好久了所以請PO上來請前輩們指點
2.如果要加個相同連結就給同一個標籤要怎麼做???

void __fastcall TForm1::Button7Click(TObject *Sender)
{
Graphics::TBitmap *Bitmap1 = new Graphics::TBitmap();

int label;
Bitmap1->LoadFromFile("C.bmp");
Image2->Picture->Assign(Bitmap1);
Bitmap1->Assign(Image2->Picture->Bitmap);
Bitmap1->PixelFormat = pf24bit;//24bit
Byte *ptr=NULL;

for (int i=0;iHeight;i )
{
ptr=(Byte*)Bitmap1->ScanLine[i];
for (int j=0;jWidth; j )
{

if(ptr[i*3]==0 && ptr[i*3 1]==0 && ptr[i*3 2]==0)
{
label=label 1;
Connect(Bitmap1,label,i,j);
}
}
}
Image2->Stretch=true;
Image2->Height *=1;
Image2->Width *=1;
Image2->Picture->Assign(Bitmap1);
Image2->Picture->SaveToFile("D.bmp");
delete Bitmap1;
}
//---------------------------------------------------------------------------
int __fastcall TForm1::Connect(Graphics::TBitmap * Bitmap1,int label, int i, int j)
{
Bitmap1->Canvas->Pixels[i][j] = label;
if (Bitmap1->Canvas->Pixels[i 1][j]==0)
{
Connect(Bitmap1,label, i 1, j);
}

if (Bitmap1->Canvas->Pixels[i 1][j-1] ==0)
{
Connect(Bitmap1,label, i 1, j-1);
}
if (Bitmap1->Canvas->Pixels[i][j-1] ==0)
{
Connect(Bitmap1,label, i , j-1);
}

if (Bitmap1->Canvas->Pixels[i- 1][j] ==0)
{
Connect(Bitmap1,label, i -1, j);
}

if (Bitmap1->Canvas->Pixels[i- 1][j 1] ==0)
{
Connect(Bitmap1,label, i - 1, j 1);
}
if (Bitmap1->Canvas->Pixels[i][j 1] ==0)
{
Connect(Bitmap1,label, i, j 1);
}
if (Bitmap1->Canvas->Pixels[i 1][j 1] ==0)
{
Connect(Bitmap1,label, i 1, j 1);
}

if (Bitmap1->Canvas->Pixels[i 1][j] ==0)
{
Connect(Bitmap1,label, i 1, j);
}

if (Bitmap1->Canvas->Pixels[i- 1][j-1]==0)
{
Connect(Bitmap1,label, i - 1, j-1);
}

}

你可以先下斷點,trace你的程式碼看看數據哪邊不合理
大概看了你的程式碼,你指定label(將畫素填入圖片中)應該會影響到後續的判斷
