| Feature | What It Does | How It Helps | |---------|--------------|--------------| | Manual point selection | Click on any point in the image to record its coordinates. | Precise control for sparse data sets. | | Automatic curve detection | Uses edge detection + spline fitting to trace continuous curves. | Speeds up extraction from dense plots. | | Multiple axis types | Handles linear, logarithmic, semi‑log (X or Y) and polar axes. | Works with most scientific graph conventions. | | Calibration wizard | Define origin and scale by marking two known points (or four for rotated axes). | Eliminates guesswork; high accuracy if calibration points are precise. | | Batch processing | Load a list of images and run the same calibration on each. | Useful for large data‑extraction projects. | | Export formats | CSV, TXT, Excel (XLSX), MATLAB‑compatible *.m files, and JSON. | Easy downstream analysis in any environment. | | Image pre‑processing | Basic contrast/brightness adjustment, rotation, and cropping within the app. | Improves edge detection on low‑quality scans. | | Annotation tools | Add labels, legends, and a “preview” overlay that shows extracted points on the original image. | Helpful for documentation and reproducibility. | Even in 2021, version 2
