我要把一張灰階圖的值給秀出來~~
所以我寫了以下的程式

[code cpp]
void __fastcall TForm1::Button1Click(TObject *Sender)
{
if(OpenPictureDialog1->Execute())
{
Image1->Picture->LoadFromFile(OpenPictureDialog1->FileName); //open image1
/*-----------------------Set Grid1---------------------------*/
int count=1;
Byte *ptr1;
StringGrid1->ColCount = Image1->Width 1;
StringGrid1->RowCount = Image1->Height 1;
for (int y = 1 ; y <= Image1->Height ; y )
StringGrid1->Cells[0][y] = y; //Title
for (int x = 1 ; x < Image1->Width*3 ; x =3)
{
StringGrid1->Cells[x][0] = x/3 1; //Title
StringGrid1->Cells[x 1][0] = x/3 1;
StringGrid1->Cells[x 2][0] = x/3 1;
}
//-----------------------------------------------------------
for (int y = 1 ; y <= Image1->Height ; y )
{
ptr1 = (Byte *)Image1->Picture->Bitmap->ScanLine[y-1];
for(int x = 1 ; x <= Image1->Width*3 ; x =3)
{
StringGrid1->Cells[count][y]=ptr1[(x-1)];
StringGrid1->Cells[count 1][y]=ptr1[(x-1) 1];
StringGrid1->Cells[count 2][y]=ptr1[(x-1) 2];
count =3;
}
count=1;
}
}
}
[/code]
但是卻出現錯誤耶~~
出現Project Project1.exe raised exception class EInvalidGraphicOperation with message'.Process stopped. Use Step or Run to continue.
可不可以幫我稍微看一下

編輯記錄

for (int y = 1 ; y <= Image1->Height ; y )
for(int x = 1 ; x <= Image1->Width*3 ; x =3)
for的終止範圍似乎有問題

恩恩~~後來又稍為嘗試了一下~~真的有點怪異
所以我又改了一些東西

[code cpp]
void __fastcall TForm1::Button2Click(TObject *Sender)
{
COLORREF color1;
byte R,G,B,gray;
int count=0,sum=0,i;
StringGrid1->RowCount=Bitmap->Height*Bitmap->Width;
for(int y=0;y<=Bitmap->Height;y )
{
for(int x=0;x<= Bitmap->Width;x )
{
color1=Bitmap->Canvas->Pixels[x][y];
R=GetRValue(color1);
G=GetGValue(color1);
B=GetBValue(color1);
gray=(R G B)/3;
count ;
StringGrid1->Cells[0][count]=count;
StringGrid1->Cells[2][count]=gray;
}
}
Series1->Add(gray,"",clBlue);
}
[/code]
我已經把灰階值顯示在第二行下
接下來可以教我如何把此值做統計並顯示在Chart裡嗎??

for(int y=0; yHeight;y )
{
for(int x=0; xWidth;x )

範圍應該是這樣,至於如何顯示在TChart,站上已有許多範例,請多多利用搜尋功能

謝謝你~~我已經找到我所需要的了!!
你所提供的也很有用~~謝謝!!
