2D Geometry API for Draw

[s-celles]

An API to store x, y as UInt16 whatever coordinate type is given

Could help for REPL (to avoid changing type)

NexPoint or NxPoint (x y)
NxSize (w h)

Point{2, UInt16}()

Using GeometryTypes.jl it will be possible to do:

using GeometryTypes
cls(nexSerial)  # default backcolor = WHITE

draw(nexSerial, LineSegment(Point(0, 0), Point(lcd_width, lcd_height)), colour)
draw(nexSerial, LineSegment(Point(0, 0), Point(lcd_width, lcd_height)))  # default forecolor = BLACK

[s-celles]

draw(nexSerial, Rectangle(Vec(x1, y1), Vec(w, h)), color)
draw(nexSerial, Rectangle(Vec(x1, y1), Vec(w, h)), color, Background.SOLIDCOLOUR)

See JuliaGeometry/GeometryTypes.jl#149 for Rectangle construction possible improvements

[s-celles]

draw(nexSerial, Picture(picid), Point(x, y))
draw(nexSerial, Picture(picid), Rectangle(x, y, w, h))
draw(nexSerial, Picture(picid), Rectangle(x, y, w, h), Point(x0, y0))

[s-celles]

draw(nexSerial, Circle(Point(0, 0), 20), color)
draw(nexSerial, Circle(Point(0, 0), 20), color, Background.SOLIDCOLOUR)

[s-celles]

draw(nexSerial, "Hello", Rectangle(x, y, w, h), font, fontcolor, backcolor, xcenter, ycenter, sta)

ToDo:

• fontcolor/backcolor should be optional Color: define 2 constants (DEFAULT_BACKCOLOR, DEFAULT_FORECOLOR) #45
• font should be optional (using Font(0) by default)
