PascalABC dasturlash tilining grafik imkoniyatlari

GraphABC moduli

• Pascalda grafik obyektlat bilan ishlash uchun GraphABC modulidan foydalaniladi.
• Grafik rejimida ishlash uchun
• uses GraphABC; yoziladi

• Grafik rejim

• PassalABC grafik ekranida (standart) gorizontal 640 va vertikal 400 nuqta mavjud.

• 640 nuqta

• 400 nuqta

• ekranning yuqori chap burchagi

• Ekranni boshqarish

• SetWindowWidth(w) - Grafik oynaning kengligini o'rnatadi;

• SetWindowHeight(h) - Grafik oynaning balandligini o'rnatadi;

• ClearWindow; - grafik oynani tozalaydi.
• ClearWindow(color); - grafik oynani belgilangan rang bilan hosil qiladi

• Grafik oynasini tozalash

• program clear;
• uses GraphABC;
• begin
• ClearWindow;
• ClearWindow (clMoneyGreen);
• end.

• Grafik sodda shakllar

• Nuqta
• chiziq
• To’rtburchak
• Aylana
• Ellips
• Sektor
• Yoy

• Nuqta

• SetPixel(x,y,color) - koordinatalari (x, y) bo’lgan nuqtaning rangi

• program tochka;
• uses GraphABC;
• begin
• SetPixel(300,200,clred);
• end.

• Chiziq

• LineTo(x,y) – Qalamni joriy holatidan (x,y) koordinatali nuqtagacha kesma chizadi va qalamning joriy holatini (x,y) nuqtaga o’tkazadi.

• x,y

• Program liniay;
• uses GraphABC;
• begin LineTo(300,200);
• end.
