小弟照著找到的3X3遮罩去寫，有中間的像素直*9剪掉周圍的像素

做出來的結果好像不太一樣，所以拿出來跟大家討論看看
並附上檔案及圖片，01是範例程式的結果，02是我自己執行的結果

以下是我使用到的.h檔
[code cpp]
//---------------------------------------------------------------------------
#ifndef TCColorH
#define TCColorH
struct TCColor
{
union
{
TColor Color;
struct
{
unsigned char Red;
unsigned char Green;
unsigned char Blue;
unsigned char Reserved;
};
};
TCColor(TColor c):Color(c){}
TCColor(unsigned char R, unsigned char G, unsigned char B):
Red(R), Green(G), Blue(B), Reserved(0){}
};
//---------------------------------------------------------------------------
#endif

[/code]


高通部分的程式

[code cpp]
Graphics::TBitmap *TempBitmap;//宣告兩個指標*TheBitmap,*TempBitmap
//TempBitmap=new Graphics::TBitmap();
TempBitmap=Image1->Picture->Bitmap;
int x,y,highpass;
for(y=1;y<=TempBitmap->Height-1;y )
{
for(x=1;x<=TempBitmap->Width-1;x )
{
TCColor a1=TempBitmap->Canvas->Pixels[x-1][y-1]; //1
TCColor a2=TempBitmap->Canvas->Pixels[x][y-1];
TCColor a3=TempBitmap->Canvas->Pixels[x 1][y-1];
TCColor a4=TempBitmap->Canvas->Pixels[x-1][y];
TCColor a5=TempBitmap->Canvas->Pixels[x][y];
TCColor a6=TempBitmap->Canvas->Pixels[x 1][y];
TCColor a7=TempBitmap->Canvas->Pixels[x-1][y 1];
TCColor a8=TempBitmap->Canvas->Pixels[x][y 1];
TCColor a9=TempBitmap->Canvas->Pixels[x 1][y 1];
int xx= ((int)a5.Red)*9;
//graylevel=((int)c.Red (int)c.Green (int)c.Blue)/3;
highpass=xx-((int)a1.Red (int)a2.Red (int)a3.Red (int)a4.Red (int)a6.Red (int)a7.Red (int)a8.Red (int)a9.Red);

//Memo1->Lines->Add(IntToStr((int)a5.Red));
//Memo1->Lines->Add(IntToStr(xx));

if(highpass>255)
{
highpass=255;
}
if(highpass<0)
{
highpass=0;
}
Image1->Canvas->Pixels[x][y]=TCColor(highpass,highpass,highpass).Color;
}
}
ShowMessage("Operation is done!");

編輯記錄

感覺上是你沒有把處理完的影像暫存起來
而是直接覆寫原始影像 導致資訊錯誤
