✨ fcft_set_scaling_filter(3) ✨

okay so bestie, welcome to the fcft corner of the manual — this one's all about fcft_set_scaling_filter, and it's genuinely a little glow-up button for your bitmap fonts 🎀

---

🌸 NAME 🌸

fcft_set_scaling_filter — configures the filter to use when downscaling bitmap fonts

---

🦋 SYNOPSIS 🦋

#include <fcft/fcft.h>

bool fcft_set_scaling_filter(enum fcft_scaling_filter filter);

---

💅 DESCRIPTION 💅

So fcft_set_scaling_filter() is the function that configures the filter the use when downscaling bitmap fonts (typically emoji fonts, iykyk 💖). Heads up though — this setting is a global mood, it affects all font instances, not just one.

⚠️ fr fr read this part: this function does not clear the glyph caches, so you should call it before any calls to fcft_codepoint_rasterize(). Caching comes for you if you're late 💀

Possible values for filter are, and yes we're listing all of them, no skips:

• FCFT_SCALING_FILTER_NONE
• FCFT_SCALING_FILTER_NEAREST
• FCFT_SCALING_FILTER_BILINEAR
• FCFT_SCALING_FILTER_IMPULSE
• FCFT_SCALING_FILTER_BOX
• FCFT_SCALING_FILTER_LINEAR
• FCFT_SCALING_FILTER_CUBIC
• FCFT_SCALING_FILTER_GAUSSIAN
• FCFT_SCALING_FILTER_LANCZOS2
• FCFT_SCALING_FILTER_LANCZOS3
• FCFT_SCALING_FILTER_LANCZOS3_STRETCHED

Now let's break down the vibes 🌈:

• FCFT_SCALING_FILTER_NONE — disables filtering. that's it, that's the whole personality, no filter no problem 🫶
• FCFT_SCALING_FILTER_NEAREST and FCFT_SCALING_FILTER_BILINEAR — these two are the traditional filters, and nearest is the fastest of the bunch ⚡
• the rest? separable convolution filters. iconic behaviour honestly 👑

And if you never call this function at all? fcft just defaults to FCFT_SCALING_FILTER_CUBIC. she picked for you 💜

⭐ RETURN VALUE ⭐

On success, fcft_set_scaling_filter() returns true. On error, false is returned. simple as that 🎀
