getPixel method
Implementation
Color getPixel(int x, int y) {
if (x < 0 || x >= width || y < 0 || y >= height) {
throw RangeError('Pixel coordinates ($x, $y) are out of bounds');
}
// Note: This method is synchronous but may be slow for large images
// Consider using toByteData() for better performance when accessing many pixels
throw UnsupportedError('getPixel is not supported on native images. '
'Use toByteData() to access pixel data asynchronously.');
