vistaでphotoshop その9

概要

vistaでphotoshopやってみる。
キャンバス作って、マンデルブロー書いて、pngで出力やってみる。

サンプルコード

var v = [];
var pixelSize = 1;
var width = 300;
var height = 300;
var maxIterations = 100;
var mandelMin = -2.5;
var mandelMax = 2.5;
var infinity = 2;
var brightness;

function draw() {
    for (var y = 0; y < height; y++) 
    {
        for (var x = 0; x < width; x++) 
        {
            var map = function(num, in_min, in_max, out_min, out_max) {
                return (num - in_min) * (out_max - out_min) / (in_max - in_min) + out_min;
            };
            var a = map(y, 0, height, mandelMin, mandelMax);
            var b = map(x, 0, width, mandelMin, mandelMax);
            var initialA = a;
            var initialB = b;
            var iterationCount = 0;
            while (iterationCount < maxIterations)
            {
                var aa = (a * a) - (b * b);
                var bb = (2 * a * b);

                var result = Math.abs(a + b);
                if (result >= infinity)
                {
                    brightness = 255;
                    break;
                }
                else
                {
                    brightness = 0;
                }
                iterationCount++;
            }
            if (brightness == 0) v.push([x, y]);
        }
    }
}
draw();
preferences.rulerUnits = Units.PIXELS;
var docObj = app.documents.add(300, 300);
var myColor = new SolidColor();
myColor.rgb.red = myColor.rgb.green = myColor.rgb.blue = 0;
myColor.rgb.red = 255;
for (var i = 0; i < v.length; i++) 
{
    var x = v[i][0];
    var y = v[i][1];
    var selReg = [[x, y], [x + 1, y], [x + 1, y + 1], [x, y + 1], [x, y]];
    activeDocument.selection.select(selReg);
    activeDocument.selection.fill(myColor, ColorBlendMode.NORMAL, 100, false);
}
var pngOpt = new ExportOptionsSaveForWeb();
pngOpt.format = SaveDocumentType.PNG;
pngOpt.optimized = true;
pngOpt.interlaced = false;
pngOpt.PNG8 = false;
var filePath = new File("/Users/ore/test8.png");
app.activeDocument.exportDocument(filePath, ExportType.SAVEFORWEB, pngOpt);
alert("ok");

以上。
