Type Alias SysDecodePngFn 

pub type SysDecodePngFn = Option<unsafe extern "C" fn(userdata: *mut c_void, allocator: *const Allocator, data: *const u8, data_len: usize, out: *mut SysImage) -> bool>;

Callback type for PNG decoding.

Decodes raw PNG data into RGBA pixels. The output pixel data must be allocated through the provided allocator. The library takes ownership of the buffer and will free it with the same allocator.
