magickPingImage method

Future<bool> magickPingImage(
  1. String fileName
)

MagickPingImage() is the same as MagickReadImage() except the only valid information returned is the image width, height, size, and format. It is designed to efficiently obtain this information from a file without reading the entire image sequence into memory.

This method runs inside an isolate different from the main isolate.

  • fileName: The image filename.

Implementation

Future<bool> magickPingImage(String fileName) async => await _magickCompute(
      _magickPingImage,
      _MagickPingImageParams(
        _wandPtr.address,
        fileName,
      ),
    );
