Scripts/Cards Generator

This script [currently missing] generates a deck of cards as a graphical bitmap suitable for visualizing card layouts. The deck contains 52 cards, a joker, two backs and a blank.

Features

• are arranged by ascending value as used in some games
• card dimension 28×40 (width, height) fits on a PocketPC screen
• picture layout allows partially covered stacking
• the bitmap above is suitable for loading "as is" with readbmp
• cards can be extracted as matrices and composed in a layout

The bitmap file

You need to have the file with the card images before using the cards in other utilities.

The easiest way is to download it from here

• right-click on the image above
• select "Save Picture As ..." or similar menu item
• choose location j\user\cards\cards28x40.png

[This part does not work]
You can create a bitmap from the generator as shown below, however the image on this page was generated with system font configuration to ensure best quality.

f_run ''    NB. show the generated cards in a form
f_save ''   NB. save to user/cards/cards28x40.bmp

Bridge

Here is an example of using the generated cards to lay out a table of bridge.

Generated with view deal'' from the script below.

require 'viewmat'

F=: readpng jpath'~user/cards/cards28x40.png'
C=: ,/}:"_1 ] 0 3 2 1{(,:~40 28) ];.3 F
T=: 16ba000

    maxd =: |:@:({.@$&>) {@;&(>./) {:@$&>
  table  =: [: > [: ,&.>/ [: ,.&.>/"1 maxd {.!.T&.> ]
    hand =: (,!.T)&.>/
    stack=: (,.~ 12&{."1)~/
    group=: [: (<.@%&13 </. ]) /:~
  shand  =: empty`([: >@hand (<C) stack@:{&.>~ group)@.(*@#)
  tabmat =: 3 3 $&, a:&,.
view     =: [:viewrgb [:table [:shand&.> tabmat
deal     =: _13(<\?~)52"_
