imageCreateFromRgba method

({TerminalImageHandle? handle, int status}) imageCreateFromRgba(Uint8List pixels, { required int width, required int height, required int stride, })

Creates a native image by copying an RGBA pixel buffer.

Implementation

({int status, TerminalImageHandle? handle}) imageCreateFromRgba(
  Uint8List pixels, {
  required int width,
  required int height,
  required int stride,
}) {
  for (final (name, value) in <(String, int)>[
    ('width', width),
    ('height', height),
    ('stride', stride),
  ]) {
    _checkUnsignedAbi(value, 0xFFFFFFFF, name);
  }
  return _guardAlloc('Failed to create RGBA image', (allocator) {
    final bytes = _copyBytes(allocator, pixels);
    final output = allocator<Uint32>()..value = 0;
    final status = _native.imageCreateFromRgba(
      bytes,
      pixels.length,
      width,
      height,
      stride,
      output,
    );
    final value = output.value;
    return (
      status: status,
      handle: value == 0 ? null : TerminalImageHandle.fromNative(value),
    );
  });
