Colour pinstripe/Display

⚠️ Warning: This is a draft ⚠️

This means it might contain formatting issues, incorrect code, conceptual problems, or other severe issues.

If you want to help to improve and eventually enable this page, please fork RosettaGit's repository and open a merge request on GitHub.

The task is to create 1 pixel wide coloured vertical pinstripes with a sufficient number of pinstripes to span the entire width of the graphics display. The pinstripes should either follow the system palette sequence or a sequence that includes Black, Red, Green, Blue, Magenta, Cyan, Yellow, White.

After filling the top quarter of the display, we switch to a wider 2 pixel wide vertical pinstripe pattern. Halfway down the display we switch to 3 pixel wide vertical pinstripe and then finally to a 4 pixels wide vertical pinstripe for the last quarter of the display.

Writes the image to stdout using the PPM format. You can either redirect that to a file, or pipe it to something like ImageMagick's ''display'' utility to view the result.

The dimensions of the image are specified by the first two values on the stack: 1366 ("%":3-) by 768 ("`"8).

Common Lisp

Using Allegro's Common Graphics. As stated in the comments, I'm using line drawing here which causes the line caps to make the edges between regions to be a bit ragged. I mention a couple of alternatives there which I'm too lazy to implement right now.

(in-package :cg-user)

;;; We only need a bitmap pane - nothing fancy
(defclass draw-pane (bitmap-pane)())

;;; close it down by clicking on it
(defmethod mouse-left-down ((pane draw-pane) buttons data)
  (declare (ignore buttons data))
  (close pane))

;;; Create the window and draw the pinstripes
(defun make-draw-window ()
  (let ((win (make-window :one :class 'draw-pane :width 300 :height 200)))
    (draw win)))

;;; Function to draw the pinstripes.  The lines are a bit ragged at the intersections
;;; between pinstripe sections due to the fact that common graphics uses round line
;;; caps and there doesn't appear any way to change that.  Could be fixed by using
;;; rectangles rather than lines or, perhaps, by setting rectangular clipping regions.

(defun draw (win)
  (do ((lwidth 1 (+ 1 lwidth))
       (top 0 bottom)
       (colors (make-array 8 :initial-contents
                           '(black red green blue magenta cyan yellow white)))
       (bottom (/ (height win) 4) (+ (/ (height win) 4) bottom)))
      ((eql 5 lwidth) t)
    (with-line-width (win lwidth)
      (do ((xpos 0 (+ xpos lwidth))
           (clr-ndx 0 (mod (+ clr-ndx 1) 8)))
           ((> xpos (width win)) t)
        (with-foreground-color (win (aref colors clr-ndx))
          (draw-line win
                     (make-position xpos top)
                     (make-position xpos bottom)))))))

M2000 Interpreter

Module names and variables with same name may exist Above and inside M2000 console layer there are 32 layers. These layers used for text/graphics and as sprites. We can make window forms above console window, any number of them and for forms 100 we can use background as layer too. Behind console layer is the background layer (the console window) and also there we can use it for printing. Also there is one more layer, the printer layer which hold a page. For eedilayers as background, console and sprites we can use Input too. This command can't be used in user windows, we have to use controls and events. Sprite layers have a priority number, so 32 is the top one. We can change priorities sending back any sprite.

Version 2 We change console width and height and put in the center of screen We use a thread to move the layer above console (and inside console form), when we push any mouse button (only in console window). Program ends when we close the modal opened window.

Simply change constant colours to {CD_BLACK, CD_WHITE} for the monochrome tasks (as redirected here).

For the print tasks redirected here, note the routine draw_to() draws 4 bands each one quarter of the page height (with truncation to whole pixels and knock-on-rounding), however cdCanvasGetSize() actually returns {width, height, width_mm, height_mm}, the canvas size in pixels and in millimetres, and from that it is assumed it would be trivial to change the calculation of h from height/4 to 1 inch, and also the "for y=1 to 4 do" to "while height do", all in that one draw_to() routine.
