Gauge Manipulation: Draw, Drag, Plot, Group¶

EasyGauge provides means to graphically interact with gauges to place and size them, combine them as a hierarchy of grouped items, and store/retrieve them and all working parameters to/from model files.

Draw¶

Draw ^.NET ^Python gives a graphical representation of a gauge. Drawing is done with the current pen in the device context associated with the desired window. Depending on the operation, handles may be displayed.

Drag¶

An operator can drag a gauge interactively over an image. Several dragging handles are available.

HitTest ^.NET ^Python determines when the mouse cursor is over a handle. When it is, the cursor shape should be changed for feedback, and a drag can take place.
Drag ^.NET ^Python moves the handle and the corresponding gauge accordingly.

In addition, if you are interacting with a polygon gauge, you can:

Use the method AddVertexAtDisplayPosition ^.NET ^Python to create a new vertex at a chosen position (typically at a mouse click)
Use the method RemoveVertexAtDisplayPosition ^.NET ^Python to remove a vertex.

Plot¶

EasyGauge can Plot gray-level values along the sampled paths and/or its derivative - useful for parameter tuning.

Point measurement gauges can plot after calling EPointGauge::Measure ^.NET ^Python.
Model fitting gauges can plot after calling MeasureSample with an index argument that lies between 0 and GetNumSamples-1 (included).
To view the corresponding sampling path, use the method Draw ^.NET ^Python with mode EDrawingMode_SampledPath ^.NET ^Python.

Group¶

Measurement gauges can be grouped (their relative placement remains fixed) to form a dedicated tool that can be moved (translated and rotated) to follow the movement of inspected items / probes before computing measurements.

Attach ^.NET ^Python associates a gauge to a mother gauge or EFrameShape ^.NET ^Python.
GetNumDaughters ^.NET ^Python, GetDaughter ^.NET ^Python, or GetMother ^.NET ^Python retrieves information relative to attached daughters or mother.
Detach ^.NET ^Python, DetachDaughters ^.NET ^Python dissociates the gauge or daughters from the mother.
