## Pages in this subsection

- [Legacy EasyGauge](index.html.md): Index of the legacy EasyGauge API topics covering workflow, gauge definitions, transition finding, calibration, and image unwarping.
- [Workflow](workflow.html.md): Overview of the legacy EasyGauge workflow: uncalibrated, calibrated, and grouped gauging approaches for measuring parts to sub-pixel accuracy.
- [Gauge Definitions](gauge_definitions.html.md): Reference for the legacy EasyGauge point, line, rectangle, circle, wedge, and polygon gauge classes, their placement, and measurement usage.
- [Find Transition Points Using Peak Analysis](find_transition_points_using_peak_analysis.html.md): Explains how the legacy EPointGauge locates edge transition points via peak analysis, including thresholding, filtering, and peak selection.
- [Find Shapes Using Geometric Models](find_shapes_using_geometric_models.html.md): Describes the legacy EasyGauge line, circle, rectangle, wedge, and polygon gauges for fitting geometric models to edges, with outlier rejection.
- [Gauge Manipulation: Draw, Drag, Plot, Group](gauge_manipulation_draw_drag_plot_group.html.md): How to draw, drag, plot, and group legacy EasyGauge gauges for graphical interaction and building hierarchical measurement tools.
- [Calibration and Transformation](calibration_and_transformation.html.md): Describes field-of-view calibration concepts and how world-to-sensor transforms like scaling, skew, perspective, and distortion affect gauging.
- [Calibration Using EWorldShape](calibration_using_eworldshape.html.md): How to calibrate a field of view with the legacy EWorldShape class using estimation, landmark points, or automatic dot-grid target analysis.
- [The Calibration Model](the_calibration_model.html.md): Details the field-of-view, advanced, and empirical calibration models used by the legacy EWorldShape class and their tunable parameters.
- [Unwarp an Image](unwarp_an_image.html.md): Explains image calibration concepts and how to unwarp a distorted image into a rectified, distortion-free image using EWorldShape.

## Optional

- [Top-level llms.txt](../../../../llms.txt): Complete documentation index.
