6. Ekranda chizmalarni xarakatlantirish
Ekranda chizmalarni xarakatlantirish uchun kerak buladigan protseduralar:
1.imagesize (x1, y1, x2, y2) – ekranning chap yuqori nuktasi va ung pastki nuktasi koordinatalaridan tugri turtburchakli soxani saklash uchun kerakbuladigan xotiraning ulchami (baytlarda olinadi);
2. getimage (x1, y1, x2, y2, p) – dinamik xotiraning berilganr maydonida to‘g‘ri to‘urtburchakli tasvirini saqlash. Bu erda – tasvirlanadigan joyning adresini saklaydigan uzgaruvchi, ya’ni kursatkich.
3. putimage (x, y, p, m) – ekranning berilgan joyiga tasvirni chikarish; bu yerda x va y – xotiraning p maydonidagi tasvirdan nusxa kuchiriladigan ekranmaydonining chap yukori nuktasi; m – tasvirni ekranga chikarish rejimi. Agar: m = 0 (NormalPut) - tasvirnikuchirish. Bunda eskisi uchib, yangisi paydo buladi (xuddiyuribketayotgandek)
m =1 (XorPut)
m = 2 (Orput) –
m = 3 (AndPut)
Masalan: quyidagi dasturda kvadrat ichidagi bo‘yalgan aylana ekran bo‘ylab xarakatlanadi.

Quyida C++ dasturida Lacetti aftomobilini tuzish programmasi berilgan.
