The bottom line is that during the MouseMove event, the application in RAM starts to occupy 1GB and more, and even after the end of this event continues to occupy so much space. What and how can I fix it? My program draws lines and rectangles, over the image, as well as cuts and saves a fragment in the picturebox.

static Point^ pointstart = gcnew Point(0,0); static array<Point>^ Points = gcnew array<Point>(100000); static int i=1, j=0, proverka=0, xs, ys, xe, ye; static array<Bitmap^>^ reserv=gcnew array<Bitmap^>(100); private: System::Void picture_MouseMove(System::Object^ sender, System::Windows::Forms::MouseEventArgs^ e) { if (proverka!=0) { if (type == 1 || type == 3) { picture->Image = reserv[j-1]; xe=Convert::ToInt32(e->X); ye=Convert::ToInt32(e->Y); pointstart->X = Convert::ToInt64(e->X); pointstart->Y = Convert::ToInt64(e->Y); Points-> SetValue (pointstart, i); if (i!=1) { Bitmap^ pic = gcnew Bitmap (picture->Image); Graphics^ g = Graphics::FromImage(pic); array<Point>^ PointsDraw = gcnew array<Point>(i); Array::Copy(Points, PointsDraw, i); g->DrawCurve(newpen, PointsDraw); picture->Image = pic; Array::Clear(PointsDraw, 0, i); } xs=xe; ys=ye; i++; } if (type == 2 || type == 4) { picture->Image = reserv[j-1]; int xw, yw; xe=Convert::ToInt32(e->X); ye=Convert::ToInt32(e->Y); if (xs < xe && ys < ye ) { xw = xe - xs; yw = ye - ys; } else { xw = xe - xs; yw = ye - ys; xs = xe; ys = ye; } Bitmap^ pic = gcnew Bitmap (picture->Image); Graphics^ g = Graphics::FromImage(pic); g->DrawRectangle(newpen, xs, ys, abs(xw), abs(yw)); picture->Image = pic; } } } private: System::Void picture_MouseUp(System::Object^ sender, System::Windows::Forms::MouseEventArgs^ e) { if (proverka!=0) { if (type == 1 || type == 3) { picture->Image = reserv[j-1]; //Задание точек pointstart->X = Convert::ToInt64(e->X); pointstart->Y = Convert::ToInt64(e->Y); Points-> SetValue (pointstart, i); array<Point>^ PointsDraw = gcnew array<Point>(i); Array::Copy(Points, PointsDraw, i); //Рисование Bitmap^ pic = gcnew Bitmap(picture->Image); Graphics^ g = Graphics::FromImage(pic); g->DrawCurve(newpen, PointsDraw); picture->Image = pic; //Сохранение reserv->SetValue (pic, j); j++; //Возвращение к начальным значениям Array::Clear(Points, 0, Points->Length); Array::Clear(PointsDraw, 0, i); i=1; proverka=0; } if (type == 2) { picture->Image = reserv[j-1]; int xw, yw; xe=Convert::ToInt32(e->X); ye=Convert::ToInt32(e->Y); if (xs < xe && ys < ye ) { xw = xe - xs; yw = ye - ys; } else { xw = xe - xs; yw = ye - ys; xs = xe; ys = ye; } Bitmap^ pic = gcnew Bitmap (picture->Image); Graphics^ g = Graphics::FromImage(pic); g->DrawRectangle(newpen, xs, ys, abs(xw), abs(yw)); picture->Image = pic; //Сохранение reserv->SetValue (pic, j); j++; //К начальным данным proverka = 0; i=1; } if (type == 4) { picture->Image = reserv[j-1]; int xw, yw; xe=Convert::ToInt32(e->X); ye=Convert::ToInt32(e->Y); if (xs < xe && ys < ye ) { xw = xe - xs; yw = ye - ys; } else { xw = xe - xs; yw = ye - ys; xs = xe; ys = ye; } Bitmap^ pic = gcnew Bitmap(picture->Image); Rectangle cloneRect = Rectangle(xs, ys, xw, yw); picture->Image = pic->Clone(cloneRect, pic->PixelFormat); Bitmap^ save = gcnew Bitmap(picture->Image); reserv->SetValue (save, j); j++; } } }

    Well, what did you expect? judging by the code, you get an array of 100 images. Even if each picture is 640x480, then it is already more than 100 mb. This is not counting overhead. by the way, static int i = 1, j = 0; static array <Bitmap ^> ^ reserv = gcnew array <Bitmap ^> (100); cause shock. The first line is that nobody uses i and j. Looking for clearer names. second, I think it’s worth replacing with something like stack <Bitmap ^> ^ reserv = gcnew stack <Bitmap ^> (); and then it turns out that the variable j is not needed. - KoVadim
  • About the stack, thanks! I’ll take into account i, j) But the problem occurs during drawing, when I start to draw RAM, it just flies away. - Zwei

    of course will fly away. picture_MouseMove is called very often. At least 10 times per second. if the proverka not zero, then in seconds 10 "mouse movements" the array will be to the eye. - KoVadim 2:19 pm
  • But, when drawing a rectangle, arrays are not used, and the memory goes away. - Zwei
