Graphics¶
The Base.Graphics interface is an abstract wrapper; specific packages (e.g., Cairo and Tk/Gtk) implement much of the functionality.
Geometry¶
- Vec2(x, y)¶
Creates a point in two dimensions
- BoundingBox(xmin, xmax, ymin, ymax)¶
Creates a box in two dimensions with the given edges
- BoundingBox(objs...)
Creates a box in two dimensions that encloses all objects
- width(obj)¶
Computes the width of an object
- height(obj)¶
Computes the height of an object
- xmin(obj)¶
Computes the minimum x-coordinate contained in an object
- xmax(obj)¶
Computes the maximum x-coordinate contained in an object
- ymin(obj)¶
Computes the minimum y-coordinate contained in an object
- ymax(obj)¶
Computes the maximum y-coordinate contained in an object
- diagonal(obj)¶
Return the length of the diagonal of an object
- aspect_ratio(obj)¶
Compute the height/width of an object
- center(obj)¶
Return the point in the center of an object
- xrange(obj)¶
Returns a tuple (xmin(obj),xmax(obj))
- yrange(obj)¶
Returns a tuple (ymin(obj),ymax(obj))
- rotate(obj, angle, origin) → newobj¶
Rotates an object around origin by the specified angle (radians), returning a new object of the same type. Because of type-constancy, this new object may not always be a strict geometric rotation of the input; for example, if obj is a BoundingBox the return is the smallest BoundingBox that encloses the rotated input.
- shift(obj, dx, dy)¶
Returns an object shifted horizontally and vertically by the indicated amounts
- *(obj, s::Real)
Scale the width and height of a graphics object, keeping the center fixed
- +(bb1::BoundingBox, bb2::BoundingBox) → BoundingBox
Returns the smallest box containing both boxes
- &(bb1::BoundingBox, bb2::BoundingBox) → BoundingBox
Returns the intersection, the largest box contained in both boxes
- deform(bb::BoundingBox, dxmin, dxmax, dymin, dymax)¶
Returns a bounding box with all edges shifted by the indicated amounts
- isinside(bb::BoundingBox, x, y)¶
True if the given point is inside the box
- isinside(bb::BoundingBox, point)
True if the given point is inside the box
