Color Cycle
 
2 Attachment(s)
A simple color cycle. It will turn one number (input) in to a RGB color Graal can understand.

PHP Code:
function ColorCycle(i) {
  temp.i = i % 114;
  temp.r = max((sin(max(i, 0) / 12)), 0.01);
  temp.g = max((sin(max(i - 16, 0) / 16)), 0.01);
  temp.b = max((sin(max(i - 36, 0) / 20)), 0.01);
  return {r, g, b};
} 



Example:
PHP Code:
//#CLIENTSIDE
for(temp.i = 0; temp.i < 255; temp.i ++) {
  showimg(200, "light2.png", x, y);
  temp.color = colorcycle(i);
  changeimgcolors(200, color[0], color[1], color[2], 0.99);
  sleep(0.05);
} 
The light will cycle through all of the colors of the rainbow.


Another example:
PHP Code:
//#CLIENTSIDE
function onCreated() {
  showimg(200, "light2.png", 200, 200);
  changeimgvis(200, 4);
  onCreateColor();
  onTimeout();
}

function onCreateColor() {
  new GuiWindowCtrl("Color_Window1") {
    profile = GuiBlueWindowProfile;
    clientrelative = true;
    clientextent = "90,90";

    canmaximize = false;
    canminimize = false;
    canmove = true;
    canresize = false;
    closequery = false;
    destroyonhide = false;
    showtop();
    text = "Color";
    x = 50;
    y = 50;
    new GuiShowImgCtrl("Color_Table") {
      x = y = 0;
      width = height = 90;
      image = "tig-colortab.png";
    }
    new GuiShowImgCtrl("Color_Cursor") {
      x = y = 0;
      image = "tig-colorcursor.png";
    }
  }
}

function onTimeout() {
  if (leftmousebuttonglobal) {
    if (mousescreenx in |Color_Window1.x + 6, Color_Window1.x + Color_Window1.width - 5| &&
      mousescreeny in |Color_Window1.y + 24, Color_Window1.y + Color_Window1.height - 5|) {
      this.mx = Color_Table.globaltolocalcoord({mousescreenx, mousescreeny});
      Color_Cursor.x = this.mx[0] - 6;
      Color_Cursor.y = this.mx[1] - 6;
      temp.color = colorcycle(this.mx[0]);
      changeimgcolors(200, color[0], color[1], color[2], 0.99);
    }
  }
  setTimer(0.05);
} 
(See attachment images for this example)
This script will allow you to select any color you want.

PHP Code:
for(temp.i = 0; temp.i < 255; temp.i ++) {
  showimg(200, "light2.png", x, y);
  temp.color = colorcycle(i);
  changeimgcolors(200, temp.color[0], temp.color[1], temp.color[2], 0.99);
  sleep(0.05);
} 
So it's not calling your function 765 times :P

Meant to change that before I released it, thanks :p.

Seems to only support hue? What about saturation and luminosity? :frown:

Well the actual thing I'm submitting is the simple color cycle lol. If I were to actually script a color table there is a more efficient way of doing it.

Some more examples:

This example will generate your own color table.
PHP Code:
//#CLIENTSIDE
for (temp.i = 0; temp.i < 115; temp.i ++) {
  showpoly(300 + i, {p[0] + i, p[1], p[0] + 1 + i, p[1] + 100});
  changeimgvis(300 + i, 4);
  temp.color = ColorCycle(i);
  changeimgcolors(300 + i, color[0], color[1], color[2], 1);
} 
This will generate another color table with a triangular shape:
PHP Code:
//#CLIENTSIDE
function onCreated() {
  temp.w = 115;
  temp.h = 10;
  for (temp.i = 0; temp.i < w * h; temp.i ++) {
    temp.color = ColorCycle(i);
    showpoly(300 + i, {p[0] + ((p[0] + i) % w), p[1] + int(i / w), (p[0] + i / 23 + 1), p[1] + int(i / w * h) + 1, (p[0] + 1)});
    changeimgcolors(300 + i, color[0], color[1], color[2], 1 - (int(i / w)) / 100);
    changeimgvis(300 + i, 4);
  }
}

Did you know of:

getimgpixel("imagename.png",posx,posy);

Returns the Graal equivalent RGB of the position in an image?
I don't know if it's related(I kind of browsed through), but you would be able to take a color map image, and use it to find the RGB values just by clicking on it.

Yes, that's what I meant by, "If I were to actually script a color table there is a more efficient way of doing it." :p

cool tig :) I like colors.

Crow 05-14-2008 08:05 PM
That's pretty awesome. I think I will find some use for this :D

Added it in for you :D

Below is an example of hue, saturation and luminosity.
PHP Code:
//#CLIENTSIDE
function onCreated() {
  this.a = 0.99;
  this.sat = 0;
  this.mx = {15, 0};
  temp.p = {screenwidth / 2, screenheight / 2};

  showimg(200, "light4.png", 200, 200);
  changeimgvis(200, 4);
  temp.color = colorcycle(this.mx[0]);
  changeimgcolors(200, color[0] - color[0] / 2 + this.sat, color[1] - color[1] / 2 + this.sat, color[2] - color[2] / 2 + this.sat, this.a);

Nice addition, I will probably be using this!

smirt362 05-15-2008 12:26 PM
I don't understand the script, but I'm understanding what it's for...very awesome!

Tigairius 05-15-2008 06:43 PM
Crow was complaining about the green channel being misplaced (not enough yellow) so the math was pretty much completely redone.
PHP Code:
function ColorCycle(i) {
  temp.i = i % 100;
  temp.r = max((sin(max(i + 8, 0) / 12)), 0.01);
  temp.g = max((sin(max(i + 1, 0) / 22)), 0.01);
  temp.b = max((sin(max(i - 26, 0) / 21)), 0.01);
  return {r, g, b};
}
