isConsideredLine method

bool isConsideredLine()

Determines if the current Artifact is considered a line based on its aspect ratio.

This method calculates the aspect ratio of the Artifact's content and checks if it falls within a specific range to determine if it should be considered a line.

Returns:

• true if the aspect ratio is less than _lineAspectRatioMin or greater than _lineAspectRatioMax, indicating that the Artifact is likely representing a line.
• false otherwise, suggesting the Artifact is not representing a line.

The aspect ratio is calculated by the aspectRatioOfContent() method as height divided by width. Therefore:

• A very small aspect ratio indicates a tall, narrow Artifact.
• A very large aspect ratio indicates a wide, short Artifact. Both of these cases are considered to be line-like in this context.

This method is useful in image processing or OCR tasks where distinguishing between line-like structures and other shapes is important.

Implementation

bool isConsideredLine() {
  final double ar = aspectRatioOfContent();
  return ar < _lineAspectRatioMin || ar > _lineAspectRatioMax;
}
