引言: 可以說明如何使用嗎？？？ 發表人 - >< face="Verdana, Arial, Helvetica"> OpenDialog1->DefaultExt=GraphicExtension(__classid(Graphics::TBitmap)); OpenDialog1->Filter=GraphicFilter(__classid(Graphics::TBitmap)); if(OpenDialog1->Execute()) { Image1->Picture->LoadFromFile(OpenDialog1->FileName); int Width1=Image1->Picture->Width; int Height1=Image1->Picture->Height; //level 0~255 int Count_R[256]={0},Count_G[256]={0},Count_B[256]={0}; TColor PixelTemp; for(int y=0;yCanvas->Pixels[x][y]; BYTE *PixelTemp2=(BYTE*)&PixelTemp; If the position is outside the clipping rectangle, reading the value of Pixels returns -1. if(PixelTemp!=-1) { Count_B[PixelTemp2[0]] =1; Count_G[PixelTemp2[1]] =1; Count_R[PixelTemp2[2]] =1; }; }; }; //將統計好的data,丟給chart 去處理 for(int i=0;i<256;i ) { Chart1->Series[0]->AddXY(i,(double)Count_R[i],""); Chart1->Series[1]->AddXY(i,(double)Count_G[i],""); Chart1->Series[2]->AddXY(i,(double)Count_B[i],""); }; }; sorry,不太會說話,這樣是不是你要的
