I need a javascript that can determine the most frequently occuring color in an image and set the windows background color to the most frequently occuring color.

Java scripters, any1 here.

Want it in Javascript. Couldn't find one.

Might be something else that can do that will work as long as I can find a way to call it through a javascript.

JavaScript is client-side scripting, you wont be able to do it even then unless you make the user run some particular thing which returns to your script.

And no, JavaScript has no image processing libraries.

Better use a Java Applet?

I would be running that off my comp itself. I would be triggering this from a software that I use which supports calling Javascripts.

Its not a web app. Sadly, I can't manage to do this on my own as I have never handled images previously and completely out of coding these days.

A brief description on how I would make the script act,
1. An image in a particular folder would be changed regularly
2. Once this image is changed, the javascript would be triggered. Incase there is a tiny application that can do that and exit, it would be fine as well.

Found this algorithm. No idea on how to implement it though

I don't get your idea even now, what language are you writing your software in? Doesnt it have image libraries?

JS can't help with images, forget it. Nor does it allow calling other executables, so using it as a link is not possible as well.

yup thats the security measure.

u may consider M$ .Net :D

Can u be less terse, elaborate it concisely.

Yaar, is it always required to use this language with all things MS, whether good or bad :-| . Its quiet annoying.

Anyways, Yup, a .NET app will do i think, whether a Windows Form or Web app. There is not much diff anyways in .NET. Even with aspx pages, code running on server will have full access to whatever resource you want.

I haven't written any softy. But a few of the softwares I use allow calling a javascript.

Good that I asked first rather than jus googling for the impossible.

Can it possible with a VB script. This does allow calling an exe for sure, can it handle images

I use a JS in one of my sites, which can handle images and picks up the color from it. I think it can't be used in ur case.

I have now managed to write an algorithm that would do my job. Can some1 convert this algorithm to vbscript or a javascript

image=read_the_image(d:\casanova.jpg)
colours_found=0
width=get_image_width(image)
height=get_image_height(image)

for (i=0;i<width;i++)
{
for (j=0;j<height;j++)
{
new_colour_found=1 //treat as is this is a new colour
pixel_colour=get_colour_at(i,j)
for (k=0;k<colours_found;k++)
{
if (colour[k][0]=pixel_colour)
{
colour[k][1]=colour[k][1]+1
new_colour_found=0 //this colour is not new
break
}
}
if (new_colour_found=1)
{
colours_found=colours_found+1
colour[colours_found][0]=pixel_colour
colour[colours_found][1]=1
}
}
}


max[0][1]=0
//finding the most frequent colour
for (k=0;k<colours_found;k++)
{
if (colour[k][1]>max[0][1])
{
max[0][0]=colour[k][0]
max[0][1]=colour[k][1]
}
}
set_desktop_background_colour(max[0][0])
