- C++ tilining grafik
- imkoniyatlari. Inisializasiyallash.
- Ekrandan foydalanish. Grafik holat.
- Funksiya grafiklarini qurish
- Grafika uchun oyna ochish
- C/C++ tilining grafik imkoniyatlarini ishga tushirish uchun quyidagi direktiva ulanishi kerak:
- # include
- Matn rejimidan grafik rejimiga o’tish uchun maxsus proseduradan foydalaniladi:
- initgraph (&gd, &gm, “ path “);
- bu erda:
- gd – drayver nomi
- gm – rejim nomi
- path – yo’l
Drayverlar .bgi fayllarida saqlanadi. Ko’pincha gd = 0 (yoki gd = DETECT) deb olinadi. Grafik rejimidan yana matn rejimiga o’tish kerak bo’lsa closegraph ( ) funksiyasi ishlatiladi - #include
- #include
- void main( )
- { int gd=0, gm ;
- ... // dastur
- getch( );
- }
- initgraph (&gd, &gm, “ c:\bc\bin “);
- Grafik dasturning strukturasi (Borland C++)
- Grafik rejimni yopish funksiyasi
- Grafik rejimni o’rnatish funksiyasi
- #include
- int main( )
- {
- initwindow(640, 480);
- ... // dastur
- getch( );
- closegraph();
- return 0;
- }
- Grafik dasturning strukturasi (Dev-C++)
- Dev-C++ da grafika bilan ishlash uchun quyidagi sozlashlarni bajarish lozim:
- graphics.h va libbgi.a (biblioteka) fayllarni yuklab oling.
- 1. graphics.h faylni C:\Dev-Cpp\include papkaga nusxa ko’chiring.
- 2. libbgi.a faylni C:\Dev-Cpp\lib papkaga nusxa ko’chiring.
- Dev-C++ ni ishga tushiring va ToolsCompiler options menyusiga kiring.
- Compiler bo’limiga o’ting va Add these commands to the linker command line ga ptichka qo’ying va uning oynasiga satrni qo’shing

- 256·256·256 = 16 777 216 (True Color)
- Chiziq va matn rangi: set color = rangini o’rnat
- setcolor ( COLOR(255,255,0) );
- Rang to’kish usuli: set fill style = rang to’kish usulini o’rnat
- setfillstyle ( usul, rang );
- 0 – usulsiz; 1 – uzluksiz; 2 – gorizontal chiziq;
- 3..6 – turli og’ma chiziqlar;
- 7..8 – setkali chiziqlar; 9..11 – nuqtali;
- Nuqta, kesma, siniq chiziq
