-
- Provides basic functionality and API for rendering gerber files. Medium-
- specific renderers should subclass GerberContext and implement the drawing
- functions. Colors are stored internally as 32-bit RGB and may need to be
- converted to a native format in the rendering subclass.
-
- Attributes
- ----------
- units : string
- Measurement units. 'inch' or 'metric'
-
- color : tuple (<float>, <float>, <float>)
- Color used for rendering as a tuple of normalized (red, green, blue)
- values.
-
- drill_color : tuple (<float>, <float>, <float>)
- Color used for rendering drill hits. Format is the same as for `color`.
-
- background_color : tuple (<float>, <float>, <float>)
- Color of the background. Used when exposing areas in 'clear' level
- polarity mode. Format is the same as for `color`.
-
- alpha : float
- Rendering opacity. Between 0.0 (transparent) and 1.0 (opaque.)
