Display an array

Inspired by APixeL

d ← adisp.New a

d is an instance of class adisp. a are args to be used when creating HTMLRenderer.

d ← adisp.window

The same as New ⍬

d ← adisp.Window s

The same as New ('Coord' 'Pixel')('Size' s)

r ← d.Draw c

c is an array of shape (height,width) containing 32-bit integers, which are the colors of each pixel.

r is either 0 or 1:

• 0: window is closed
• 1: window is not closed

c ← adisp.RGBA f

Convert the rank 1 cells of f (0.0-1.0 float r g b a) to the corresponding color array of shape (¯1↓⍴f).

c ← adisp.RGB f

Convert the rank 1 cells of f (0.0-1.0 float r g b) to the corresponding color array of shape (¯1↓⍴f).

c ← adisp.Gray y

Convert each of y (luminance, 0.0-1.0 float) to the corresponding color integer.

c ← adisp.Hex h

h is color in one of these hexadecimal forms:

• 'RGB' (each letter is duplicated, = 'RRGGBB')
• 'RGBA' (each letter is duplicated, = 'RRGGBBAA')
• 'RRGGBB'
• 'RRGGBBAA'

c is the corresponding color.

f ← adisp.ToRGBA c

Convert color c back to the RGBA components f.
