GLUTBITMAPCHARACTER(3)

💖 GLUTBITMAPCHARACTER(3) 💖

okay so bestie, welcome to the glutBitmapCharacter page from the OpenGLUT manual — specifically the bitmapfont corner of the library. pull up a chair, grab a boba, we're drawing letters ✨

---

🎀 NAME 🎀

glutBitmapCharacter — draw a bitmapped character. that's it. that's the whole job. she draws ONE character. one. a single lil glyph. 💅

---

📚 LIBRARY 📚

OpenGLUT — the bitmapfont section, no cap.

---

✨ SYNOPSIS ✨

#include <openglut.h>

void
glutBitmapCharacter(void *font, int character);

like. look at her. two args. she's not complicated, she's just efficient. 👑

---

🫶 PARAMETERS 🫶

• font — a bitmapped font identifier. the vibe check of which font you're repping. 🦋
• character — a character code. the actual glyph you want her to draw, as an int. 🍓

---

🌸 DESCRIPTION 🌸

so here's the tea: glutBitmapCharacter draws a character at the current OpenGL raster position, using a bitmapped font. that's the whole move. slay.

and then — because she's a considerate queen — the raster position gets advanced by the width of the character. so if you call her again, you'll draw the next char right after. it's giving "typewriter energy" fr fr. 🎀

now. the important part. the listen to me bestie part. literally nothing is drawn, and the raster position is left completely unaffected, when ANY of these three things happen:

• character is out of range
• font is not a valid OpenGLUT bitmap font
• The current OpenGL raster position is invalid

so if you're staring at a blank screen wondering where your gorgeous little letter went... check those three. one of them ate your character. 💀

---

⚠️ CAVEATS ⚠️

glutBitmapString() is generally more efficient for strings of characters. so if you're out here calling glutBitmapCharacter in a loop for a whole sentence, bestie... there's a better way. no cap. use the string one. 🫶

cute lil sign-off moment: this page is dated UNDATED, and the footer reads UNTITLED() — iconic honestly, she didn't even name herself, main character energy 🌈💖 go draw some letters bestie 🦋
