🎨 color_blit — solid color BLIT operation 💅

okay so welcome to the Kernel API Manual, bestie — this page is literally called color_blit(9) and it's giving "i fill rectangles with one (1) color and i do it flawlessly" energy. no cap, let's get into it 🫶

🏷️ NAME

color_blit — solid color BLIT operation ✨

---

🌸 SYNOPSIS

void color_blit (int width , int height , int pitch , int dest , int rop
, int what , int blit_bpp , struct fb_info *info );

that's the whole signature, copy it exactly, do not come for me about the spacing, that's how it's written 💀

---

🎀 ARGUMENTS

okay so there are eight (8) of these and each one is doing its own little job. main character energy, every single one 🌈

• width — width of destination, like how wide the thing you're painting is 📏
• height — height of destination, the vertical situation 🦋
• pitch — pixels per line of the buffer, iykyk
• dest — address of first pixel to write to, the spot where the slay begins ✨
• rop — raster operation
• what — color to transfer, like the actual color, the vibe of it 🎨
• blit_bpp — pixel format which can be different from the framebuffer's pixelformat (yes, different, and that's fine, it's allowed 🙈)
• info — literally listed as -- undescribed -- in the docs, so the docs simply did not describe it. not me making something up to fill the void, absolutely not, we respect the silence 🤐

---

📖 DESCRIPTION

A BLIT operation which can be used for color fill/rectangular fill 👑

so like. you have a rectangle. you have a color. you want the rectangle to BE that color. that's it, that's the whole gig, and it ate 🔥
