image_tile and vector_image
« on: March 23, 2017, 05:22:41 PM »
Hi guys, its me again.

Today I tried to practice with image_tile - since I have almost no experience with it.
To get started I figured out some simple dialog, that uses Lee Mac's Bitmaps - the rotation button:



It uses 1 disabled edit_box and 1 disabled toggle - to display information.

Code - Auto/Visual Lisp: [Select]
  1. (defun C:test ( / *error* dcl des dch dcf e o cen ang ll ur )
  2.  
  3.   (defun *error* ( msg )
  4.     (and (< 0 dch) (unload_dialog dch))
  5.     (and (eq 'FILE (type des)) (close des))
  6.     (and (eq 'STR (type dcl)) (findfile dcl) (vl-file-delete dcl))
  7.     (and msg (or (wcmatch (strcase msg) "*BREAK,*CANCEL*,*EXIT*") (princ (strcat "\nError: " msg)) ))
  8.     (princ)
  9.   ); defun *error*
  10.  
  11.   (cond
  12.     (
  13.       (not
  14.         (and (setq dcl (vl-filename-mktemp nil nil ".dcl")) (setq des (open dcl "w"))
  15.           (mapcar (function (lambda (x) (princ (strcat "\n" x) des)))
  16.             '(
  17.               "RotateObject : dialog"
  18.               "{ label = \"Rotate Object\";"
  19.               "  : column"
  20.               "  { : image_button { key = \"img\" ; width = 5.5 ; aspect_ratio = 1.0; alignment = centered; fixed_width = true; fixed_height = true; } " ; 32x32 image
  21.               "    : edit_box { label = \"Angle\"; key = \"eb\"; alignment = centered; edit_width = 12; fixed_width = true; is_enabled = false; value = \"0\"; }" ; info
  22.               "    : row"
  23.               "    { : button { label = \"Pick object >>\"; key = \"pick\"; alignment = centered; width = 5; fixed_width = true; }"
  24.               "      : toggle { key = \"p\"; is_enabled = false; value = 0; }" ; info
  25.               "    }"
  26.               "  }"
  27.               "  spacer;"
  28.               "  ok_cancel;"
  29.               "  : text { label = \"\"; key = \"err\"; }"
  30.               "}"
  31.             )
  32.           ); mapcar
  33.           (not (setq des (close des))) (< 0 (setq dch (load_dialog dcl)))
  34.         ); and
  35.       ); not
  36.       (princ "\nUnable to write or load the DCL file.")
  37.     )
  38.     (
  39.       (progn
  40.         (setq ang 0)
  41.         (while (not (member dcf '(0 1)))

Trouble is:
  • I have no idea how to use vector_image with that list, to display the image.
  • The action_tile doesn't work for the image - why? - the idea was to increment the angle by 15 units
:thinking:

Please explore the contents of the zip file attached in the DCL Bitmaps thread - several examples have been included.

Thank you Lee!
I've found this gem of yours:

  16. (defun LM:DisplayBitmap ( key lst / i j s x y )

  18.   (repeat (setq i s)
  19.     (setq j 1)
  20.     (repeat s
  21.       (setq x (cons j x)

  23.         j (1+ j)
  24.       )
  25.     )
  26.     (setq i (1- i))
  27.   )
  28.   (start_image key)
  29.   (fill_image 0 0 (dimx_tile key) (dimy_tile key) -15)
  30.   (mapcar 'vector_image x y x y lst)
  32. )

I tend to ignore information - when too much of it is provided, I become distracted. :)
Before creating this thread I was trying to learn (atleast something) from your JustifyBasePoint program - but the content was too confusing for me. :D

Now just one issue left - the action_tile - whats wrong with it?

BTW Now that the image is displayed, I've modified the above code.

The image tile will need to be an image_button tile in order to be assigned an action.

Man, I feel so stupid  :oops:

Also I was about to ask how the tile's size should be determined, depending on the AxB image bit size, until I browsed in: DCL-Bitmaps\Tile Definitions\ImageTiles.dcl

This is the final result (I also modified the original code) :


You are a great tutor, Lee!
Everytime I try to learn some new aspect of the lisp world - I see that you've been there already, perfecting it.
Like this LM:DisplayBitmap looks so easy and comfortable to use, that IMO it deserves a place within the standad tile functions (like action_tile/set_tile) ! :-)
