Rasmni chizish yoki matnni tasvirga chiqarish ikki bosqichda bajariladi.
Avvalo chizishda ishlatiladigan ranglarni tanlash kerak. Chizish uchun kerak bo‘ladigan rangni ishlatish uchun rasm palitrasiga qo‘shish kerak bo‘ladi. Bu ishni har bir rang uchun hatto qora va oq ranglar uchun ham bajarish zarur.
imageColorAllocate(img, a, b, c)funksiyasi – chizish uchun kerak bo‘ladigan rangni aniqlaydi (bu funksiya qaytaradigan butun son, chizadigan funksiyalarda ishlatiladi). Birinchi parametr – image identifier, keyin 0 dan 255 gacha bo‘ldan uchta sonlar keladi – ular RGB tizimidagi red, green, blue qiymatlariga mos.
Tasvirda chizish uchun, bir necha har xil funksiya mavjud – kerakli shakllarga qarab bular – chiziq, yoy, ko‘pburchak yoki matn bo‘lishi mumkin.
Chizish funksiyasi quyidagi parametrlarni ishlatadi:
• tasvirning identifikatori;
• boshlang’ich va ba’zi hollarda ob’ektning oxirgi koordinatalari;
• rang;
• matnni chiqarish uchun shrift haqida ma’lumot.
