View source for Colour pinstripe/Display

{{task|Test card}}

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, &nbsp; or a sequence that includes: 
<br>black, &nbsp; red, &nbsp; green, &nbsp; blue, &nbsp; magenta, &nbsp; cyan, &nbsp; yellow, &nbsp; and &nbsp; white:
::* &nbsp; after filling the top quarter, switch to a wider 2 pixel wide vertical pinstripe pattern,
::* &nbsp; halfway down the display, switch to 3 pixel wide vertical pinstripe,
::* &nbsp; 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.

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.

;;; 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.

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.

A color pinstripe has a width and a box.

To make a color pinstripe given a width and a box:
Put the width into the color pinstripe's width.
Put the box into the color pinstripe's box.

To draw a color pinstripe:
Put the color pinstripe's box into a bound box.
Put the color pinstripe's width into a width.
Imagine a box with the bound's left and the bound's top and the width and the bound's bottom.
Put the bound's right divided by the width into an amount.
Loop.
If a counter is past the amount, exit.
Draw and fill the box with the black color. Move the box right the width.
Draw and fill the box with the red color. Move the box right the width.
Draw and fill the box with the green color. Move the box right the width.
Draw and fill the box with the blue color. Move the box right the width.
Draw and fill the box with the magenta color. Move the box right the width.
Draw and fill the box with the cyan color. Move the box right the width.
Draw and fill the box with the yellow color. Move the box right the width.
Draw and fill the box with the white color.
Repeat.

To draw the next color pinstripe given a color pinstripe:
Add 1 pixel to the color pinstripe's width.
Move the color pinstripe's box down the color pinstripe's box's height.
Draw the color pinstripe.</lang>
