STRUCT MPCC_BLND_CFG(9)

🎀 struct mpcc_blnd_cfg(9) 🎀

okay so bestie, welcome to the Kernel API Manual ✨ we're about to get into struct mpcc_blnd_cfg and honestly? it's giving "blending configuration" main character energy 💅 this is the struct that holds all your MPCC blending vibes, no cap.

🌸 NAME 🌸

struct mpcc_blnd_cfg — MPCC blending configuration 🫶

✨ SYNOPSIS ✨

struct mpcc_blnd_cfg {
    struct tg_color black_color;
    enum mpcc_alpha_blend_mode alpha_mode;
    bool pre_multiplied_alpha;
    int global_gain;
    int global_alpha;
    bool overlap_only;
    int bottom_gain_mode;
    int background_color_bpc;
    int top_gain;
    int bottom_inside_gain;
    int bottom_outside_gain;
 };

like, that's the whole shape of it, copy it exactly please 🙈

💖 Members 💖

• black_color — background color. literally the background color, that's the whole job 🖤
• alpha_mode — the alpha blend mode. it's an MPCC_ALPHA_BLND_MODE, iykyk.
• pre_multiplied_alpha — whether the pixel color values were pre-multiplied by the alpha channel, as an MPCC_ALPHA_MULTIPLIED_MODE. so like, were they already multiplied or not, bestie 🌈
• global_gain — used when the blend mode considers both pixel alpha and plane. both, not one, both 👑
• global_alpha — the plane alpha value. plane alpha. that's it, that's the whole vibe ✨
• overlap_only — whether overlapping of different planes is allowed. yes/no situation 🦋
• bottom_gain_mode — the blend mode for the bottom gain setting 🌸
• background_color_bpc — the background color for bpc 🎀
• top_gain — top gain setting, slay ⭐
• bottom_inside_gain — blend mode for bottom inside 💜
• bottom_outside_gain — blend mode for bottom outside 💀
