467 | ; XPAL uses two colors from the current color table as |
---|
468 | ; drawing foreground and background colors. These are used |
---|
469 | ; for the RGB plots on the left, and the current index marker on |
---|
470 | ; the right. This means that if the user set these two colors |
---|
471 | ; to the same value, the XPAL display could become unreadable |
---|
472 | ; (like writing on black paper with black ink). XPAL minimizes |
---|
473 | ; this possibility by noting changes to the color map and always |
---|
474 | ; using the brightest available color for the foreground color |
---|
475 | ; and the darkest for the background. Thus, the only way |
---|
476 | ; to make XPAL's display unreadable is to set the entire color |
---|
477 | ; map to a single color, which is highly unlikely. The only side |
---|
478 | ; effect of this policy is that you may notice XPAL redrawing |
---|
479 | ; the entire display after you've modified the current color. |
---|
480 | ; This simply means that the change has made XPAL pick new |
---|
481 | ; drawing colors. |
---|
482 | ; |
---|
483 | ; The new color tables are saved in the COLORS common and loaded |
---|
484 | ; to the display. |

---|
486 | ; @examples |
---|
487 | ; The XPAL widget has the following controls: |
---|
488 | ; |
---|
489 | ; Left: Three plots showing the current Red, Green, and Blue vectors. |
---|
490 | ; |
---|
491 | ; Center: A status region containing: |
---|
492 | ; 1) The total number of colors. |
---|
493 | ; 2) The current color. XPAL allows changing |
---|
494 | ; one color at a time. This color is known as |
---|
495 | ; the "current color" and is indicated in the |
---|
496 | ; color spectrum display with a special marker. |
---|
497 | ; 3) The current mark index. The mark is used to |
---|
498 | ; remember a color index. It is established by |
---|
499 | ; pressing the "Set Mark Button" while the current |
---|
500 | ; color index is the desired mark index. |
---|
501 | ; 4) The current color. The special marker used in |
---|
502 | ; color spectrum display prevents the user from seeing |
---|
503 | ; the color of the current index, but it is visible |
---|
504 | ; here. |
---|
505 | ; |
---|
506 | ; A panel of control buttons, which do the following when |
---|
507 | ; pressed: |
---|
508 | ; |
---|
509 | ; Done: Exits XPAL. |
---|
510 | ; |
---|
511 | ; Predefined: Starts XLOADCT to allow selection of one of the |
---|
512 | ; predefined color tables. |
---|
513 | ; |
---|
514 | ; Help: Supplies help information similar to this header. |
---|
515 | ; |
---|
516 | ; Redraw: Completely redraws the display using the current |
---|
517 | ; state of the color map. |
---|
518 | ; |
---|
519 | ; Set Mark: Set the value of the mark index to the |
---|
520 | ; current index. |
---|
521 | ; |
---|
522 | ; Switch Mark: Exchange the mark and the current index. |
---|
523 | ; |
---|
524 | ; Copy Current: Every color lying between the current |
---|
525 | ; index and the mark index (inclusive) is given |
---|
526 | ; the current color. |
---|
527 | ; |
---|
528 | ; Interpolate: The colors lying between the current |
---|
529 | ; index and the mark index are interpolated linearly |
---|
530 | ; to lie between the colors of two endpoints. |
---|
531 | ; save: Allows to save the palette which is currently |
---|
532 | ; on the screen. When we press this hotkey, there is a |
---|
533 | ; widget who appear and ask: |
---|
534 | ; 1) the name of the palette we want to save. |
---|
535 | ; 2) The number of the palette we may want to erase |
---|
536 | ; by the new palette. If there is not any number |
---|
537 | ; specified, the new palette is add to elders. |
---|
538 | ; 3) The name of the file containing palettes. |

---|
543 | ; current color. |
---|
544 | ; |
---|
545 | ; Right: A display which shows the current color map as a series of |
---|
546 | ; squares. Color index 0 is at the upper left. The color index |
---|
547 | ; increases monotonically by rows going left to right and top |
---|
548 | ; to bottom. The current color index is indicated by a special |
---|
549 | ; marker symbol. There are 4 ways to change the current color: |
---|
550 | ; 1) Press any mouse button while the mouse |
---|
551 | ; pointer is over the color map display. |
---|
552 | ; 2) Use the "By Index" slider to move to |
---|
553 | ; the desired color index. |
---|
554 | ; 3) Use the "Row" Slider to move the marker |
---|
555 | ; vertically. |
---|
556 | ; 4) Use the "Column" Slider to move the marker |
---|
557 | ; horizontally. |
