if mouse_check_button_pressed(mb_left) && pickMode = true
{
hue = surface_getpixel ( artSurface [ pages ] , mouse_x , mouse_y );
saturation = surface_getpixel ( artSurface [ pages ] , mouse_x , mouse_y );
value = surface_getpixel ( artSurface [ pages ] , mouse_x , mouse_y );
}
Is there any way I can pick a color of a surface using H.S.V?
It's saying when you press the mouse button and pickMode is on the color will be the color under the mouse coordinates.
pickMode is activated by pressing "P".
There are multiple pages so you can animate, which is why the surface is an array.

If you wanted to get HSV from a surface pixel, get the pixel color and then use color_* functions on it:
var col = surface_getpixel ( artSurface [ pages ] , mouse_x , mouse_y );
var hue = color_get_hue(col);
var sat = color_get_saturation(col);
var val = color_get_value(col);

By default, the cursor is at the left-top of the preview cell .
I've changed the relative position of the preview using transform: translate(-50%, -50%),so the cursor can be at the center on the preview while dragging.
But then I find the guide line doesn't fit along with the changed preview, it's still works according to the original position of the preview.
I've tried some 'offset' API on the docs but still can't work it out.
In this pic, I draw the red box, which is the original position of the preview, and the guide line works wrong
functions concerning the question are on below
const draggingPreview = () => {
const elt = document.createElement("div");
elt.style.width = '60px';
elt.style.height = '60px';
elt.style.transform = "translate(-50%,-50%)";
return elt;
};

I followed threejs documentation in vuejs project to import image using :
texture.load( "./clouds" )
This code is not working, I have to import image using require :
texture.load( require( "./clouds.png" ) )
Now I want to use functions for sucess or error, so thank's to the internet i found that
texture.load( require( "./clouds.png" ), this.onSuccess, this.onProgress, this.onError )
The problem is in success function, I want to create a cube with texture and nothing happened. I also tried on success function to add color in material but it didn't work.
onSuccess( image ) {
this.material = new THREE.MeshLambertMaterial( {
color: 0xf3ffe2,
map: image
}
this.generateCube()
}
generateCube() {
let geometry = new THREE.BoxGeometry( 100, 100, 100 );
this.forme = new THREE.Mesh( geometry, this.material );
this.forme.position.z = -200
this.forme.position.x = -100
this.scene.add( this.forme );
},
Your problem is not related to VueJS /ThreeJs (again ^^), you should learn how to use this inside a callback, here is a E6 fix :
texture.load( require( "./clouds.png" ), t => this.onSuccess(t), e => this.onProgress(e), e => this.onError(e) )
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Arrow_functions
You can put your images in the "public" folder.
And then you can load your texture by
texture.load( "/clouds.png" )
Using cytoscape.js to draw a graph. I need to add circle above the node at top-right position. After drawing the graph, is there any API wherein we can get positions of nodes.
Also, I have used the code as follows:
elements : {
nodes : [ {
data : {
id : '1',
name : 'A'
}
}
]
}
var pos = cy.nodes("#1").position();
'#1' is the ID of the node in the data attribute. However, we are not able to add the node/circle at that exact position.
If you want to get something like:
then this code adds the circle to a node knowing it's id:
function addCircle(nodeId, circleText){
var parentNode = cy.$('#' + nodeId);
if (parentNode.data('isCircle') || parentNode.data('circleId'))
return;
parentNode.lock();
var px = parentNode.position('x') + 10;
var py = parentNode.position('y') - 10;
var circleId = (cy.nodes().size() + 1).toString();
parentNode.data('circleId', circleId);
cy.add({
group: 'nodes',
data: { weight: 75, id: circleId, name: circleText, isCircle: true },
position: { x: px, y: py },
locked: true
}).css({
'background-color': 'yellow',
'shape': 'ellipse',
'background-opacity': 0.5
}).unselectify();
}
// ...
addCircle('1', 'Bubble A');
but it must be called after the node's positions are known, when the layout settles down.
The locking is there to prevent that node and it's circle get apart.
jsFiddle demo: http://jsfiddle.net/xmojmr/wvznb9pf/
Using compound node which would keep the node and it's circle together would be probably better, once the support for positioning child nodes is implemented.

I am building a webstore, where the quantity of displayed products is dinamically changing, by pressing "Show more" button. Background color should be changing multiple times while scrolling down and I found this article, which solves this problem, but it has fixed page height. Is it possible to change that?
You use a parameter to control the adaption rate and set this according to your needs if you don't know the page size on forehand (because a dynamic load for instance).
cStart = [250, 195, 56] // Gold
, cEnd = [179, 217, 112] // Lime
, cDiff = [cEnd[0] - cStart[0], cEnd[1] - cStart[1], cEnd[1] - cStart[0]];
$(document).ready(function(){
$(document).scroll(function() {
var speed = 0.0005;
var p = $(this).scrollTop()* speed;
p = Math.min(1, Math.max(0, p)); // Clamp to [0, 1]
var cBg = [Math.round(cStart[0] + cDiff[0] * p), Math.round(cStart[1] + cDiff[1] * p), Math.round(cStart[2] + cDiff[2] * p)];
$("body").css('background-color', 'rgb(' + cBg.join(',') +')');
});
});
How do I add a drop shadow (with defined distance, size etc) using Photoshop scripting?
Current JS Code
var fontSize = 14;
var fontName = "Arial-Bold"; // NB: must be postscript name of font!
// This is the colour of the text in RGB
//Click foreground colour in Photoshop, choose your colour and read off the RGB values
//these can then be entered below.
var textColor = new SolidColor();
textColor.rgb.red = 255;
textColor.rgb.green =255;
textColor.rgb.blue = 255;
var newTextLayer = doc.artLayers.add();
newTextLayer.kind = LayerKind.TEXT;
newTextLayer.textItem.size = fontSize;
newTextLayer.textItem.font = fontName;
newTextLayer.textItem.contents = ++Count;
newTextLayer.textItem.color = textColor;
newTextLayer.textItem.kind = TextType.PARAGRAPHTEXT;
newTextLayer.textItem.height = fontSize;
newTextLayer.textItem.width = doc.width -20;
//The line below is the text position (X Y) IE; 10 Pixels Right 10 Pixels Down
newTextLayer.textItem.position = Array(10, 12);
// Can be RIGHTJUSTFIED LEFTJUSTIFIED CENTERJUSTIFIED
newTextLayer.textItem.justification=Justification.CENTERJUSTIFIED;
I believe there is no API function for this.
The best you can do is to use Scriptlistner.
The code that it generates then can be used in your script.
Here are some similar discussion with Scriptlistner-generated code:
