@override PwBox layout(Context context, BoxConstraints constraints)

layout API.

Implementation

@override
PwBox layout(Context context, BoxConstraints constraints) {
  final PdfRaster? raster = PdfImageCodec.decode(image.bytes);
  final double iw = raster == null
      ? (width ?? 120)
      : (dpi != null
            ? raster.width * 72 / dpi!
            : width ?? raster.width.toDouble());
  final double ih = raster == null
      ? (height ?? 80)
      : (dpi != null
            ? raster.height * 72 / dpi!
            : height ??
                  (width != null && raster.width > 0
                      ? width! * raster.height / raster.width
                      : raster.height.toDouble()));
  final PwSize size = constraints.constrain(PwSize(iw, ih));
  return _ImageBox(size, image.bytes, raster);
