There’s not that much information about the (Vortex) KBT Pure Pro keyboard on the internet so I thought I’d add my notes here.

Layout:
  1x15
  1.5 1x12 1.5
  1.75 1x11 2.25
  2 1x13
  1.25 1x2 1.25 4.5 1x6

(1 unit = 0.75" or about 19mm)
Notable weird key sizes:
  \          1
  Backspace  1
  Del        1.5
  L Shift    2
  R Shift    1
  R Ctrl     1
  System     1
  Space      4.5
  R Alt      1

I’ve been playing with using Lua to generate parts of my wiki pages, below is the code to generate a simple SVG of the Pure Pro’s layout.

keyboard_svg_layout.lua

--noescape--

local tag = doku.xml_tag

local unit = 19*2  -- Unit size, mapped straight to pixels
local space = 4    -- Spacing between keys (as pixels again)

local halfspace = space/2
local doublespace = space*2

local fontsize = 10

local layout = {
  {1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1},
  {1.5, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1.5},
  {1.75, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 2.25},
  {2, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1},
  {1.25, 1, 1, 1.25, 4.5, 1, 1, 1, 1, 1, 1}
}

local keys = {
  {'esc', '1', '2', '3', '4', '5', '6', '7', '8', '9', '0', '-', '=', '\\', 'BS'},
  {'tab', 'q', 'w', 'e', 'r', 't', 'y', 'u', 'i', 'o', 'p', '[', ']', 'del'},

}

local scene = {}

local background = tag('rect', {width="100%", height="100%", fill="#ddd", stroke="black"})
table.insert(scene, background)

for row=1, #layout do
  x = unit
  for col=1, #layout[row] do

    local rect = tag('rect', {x=x+halfspace,
                             y=(row*unit)+halfspace,
                             rx=halfspace,
                             ry=halfspace,
                             width=(layout[row][col]*unit)-space,
                             height=unit-space,

                             stroke="black"})

    table.insert(scene, rect)


    local sizetext = tag('text', {x=x+doublespace,
                                  y=((row)*unit)+space+fontsize,

                                  tostring(layout[row][col]))

    table.insert(scene, sizetext)


    if keys[row] and keys[row][col] then
      local keytext = tag('text', {x=x+doublespace,
                                  y=((row)*unit)+(2*fontsize)+(3*space),
                                  fill="#111",
                                  style='font-size: ' .. fontsize .. 'px'},
                                  keys[row][col])

      table.insert(scene, keytext)
    end

    x = x + (layout[row][col]*unit)
  end
end

-- Keyboard is 15 units by 5 units (+1 each side for padding)
print(tag('svg', {width=(unit*17), height=(unit*7)}, scene))
