printOptimizedImage static method

Future<bool> printOptimizedImage(String imagePath, { int width = 0, Alignment alignment = Alignment.centerLeft, int threshold = 128, bool dither = true, })

Optimize an image for thermal printing and print it.

Adjusts an image for better quality on thermal printers.

• imagePath: Path to the image file
• width: Width to resize the image (0 = printer default)
• alignment: Image alignment (left, center, right)
• threshold: Threshold for binarization (0-255)
• dither: Whether to apply dithering

Returns true if printing was successful.

Implementation

static Future<bool> printOptimizedImage(
  String imagePath, {
  int width = 0,
  Alignment alignment = Alignment.centerLeft,
  int threshold = 128,
  bool dither = true,
}) async {
  try {
    // Load the image
    final File imageFile = File(imagePath);
    final Uint8List imageBytes = await imageFile.readAsBytes();

    // Optimize the image for thermal printing
    final optimizedBytes = await ImageUtils.optimizeForThermalPrinting(
      imageBytes,
      threshold: threshold,
      dither: dither,
    );

    // Print the optimized image
    return await printImageBytes(
      optimizedBytes,
      width: width,
      alignment: alignment,
    );
  } catch (e) {
    print('Error printing optimized image: $e');
    return false;
  }
