Detailed Description¶

Utility macros and functions for graphics operations.

This module provides commonly used utility macros and inline functions to simplify graphics programming and reduce code duplication. These utilities cover common operations like value comparison, clamping, and boundary checking.

Includes:

MIN/MAX macros for value comparison
Clamping function for range constraint
Additional graphics-specific helpers

Functions Documentation¶

function clamp_i32¶

static inline int32_t clamp_i32(
    int32_t v,
    int32_t lo,
    int32_t hi
)

Macros Documentation¶

define MAX¶

#define MAX(
    a,
    b
)
((a) > (b) ? (a) : (b))

Return the maximum of two values.

Parameters:

a First value to compare.
b Second value to compare.

Return: The maximum value.

Note: Only defined if not already defined elsewhere.

Evaluates to the greater of the two arguments. Arguments are evaluated only once when possible.

define MIN¶

#define MIN(
    a,
    b
)
((a) < (b) ? (a) : (b))

Return the minimum of two values.

Parameters:

a First value to compare.
b Second value to compare.

Return: The minimum value.

Note: Only defined if not already defined elsewhere.

Evaluates to the lesser of the two arguments. Arguments are evaluated only once when possible.
