render method

CaptureImage render(TerminalCapture capture)

Renders capture through the Ultraviolet raster backend.

Strict profiles reject unsupported content instead of silently replacing it. Non-strict profiles return diagnostics alongside their output.

Implementation

CaptureImage render(TerminalCapture capture) {
  final buffer = capture.toBuffer();
  try {
    final renderer = RasterTerminalRenderer(font: font, options: options)
      ..resize(capture.columns, capture.rows);
    renderer
      ..render(buffer)
      ..flush();
    final image = renderer.image!;
    return CaptureImage(
      png: Uint8List.fromList(img.encodePng(image)),
      width: image.width,
      height: image.height,
      columns: capture.columns,
      rows: capture.rows,
      diagnostics: renderer.diagnostics
          .map((item) => item.toString())
          .toList(),
    );
  } finally {
    buffer.dispose();
  }
}
