enum class InputType
Input type.
All geometric primitives expect a 1d array of coordinates. Coordinates range from 0.0 (left, top) to 1.0 (right, bottom).
Values:
- enumerator UNKNOWN
unknown type, the operator tries to guess the type by inspecting the tensor
- enumerator COLOR
RGB or RGBA color 2d image.
- enumerator COLOR_LUT
single channel 2d image, color is looked up
- enumerator POINTS
point primitives, one coordinate (x, y) per primitive
- enumerator LINES
line primitives, two coordinates (x0, y0) and (x1, y1) per primitive
- enumerator LINE_STRIP
line strip primitive, a line primitive i is defined by each coordinate (xi, yi) and the following (xi+1, yi+1)
- enumerator TRIANGLES
triangle primitive, three coordinates (x0, y0), (x1, y1) and (x2, y2) per primitive
- enumerator CROSSES
cross primitive, a cross is defined by the center coordinate and the size (xi, yi, si)
- enumerator RECTANGLES
axis aligned rectangle primitive, each rectangle is defined by two coordinates (xi, yi) and (xi+1, yi+1)
- enumerator OVALS
oval primitive, an oval primitive is defined by the center coordinate and the axis sizes (xi, yi, sxi, syi)
- enumerator TEXT
text is defined by the top left coordinate and the size (x, y, s) per string, text strings are define by InputSpec::text_

Public Functions

- inline InputSpec(const std::string tensor_name, InputType type)
Public Members
- std::string tensor_name_
name of the tensor containing the input data
- InputType type_
input type
- float opacity_ = 1.f
layer opacity, 1.0 is fully opaque, 0.0 is fully transparent
- int32_t priority_ = 0
layer priority, determines the render order, layers with higher priority values are rendered on top of layers with lower priority values
- std::vector<float> color_ = {1.f, 1.f, 1.f, 1.f}
color of rendered geometry
- float line_width_ = 1.f
line width for geometry made of lines
- float point_size_ = 1.f
point size for geometry made of points
- std::vector<std::string> text_
array of text strings, used when type_ is text.
