hi, I have draw something using canvas on the form, then later, i wish to cutt out some portion of the canvas and save it into picture file, is it possible to do so.... can anyone help me

Graphics::TBitmap *bmp = new Graphics::TBitmap;
bmp->Canvas->CopyRect(.....);

用這個東西。你就可以把 canvas 丟在 bmp 然後 savetofile..... 就可以存出去了。

It's run perfect. thank you.
