My first post was about leaving a mark in this world.
It was a long time ago since I wrote it, but I still have the same fillings.
Now I can say I'm starting to make that mark... it might take several years, but finally I will be sure all I did was not in vain.

You may do not know what I'm talking about, but I can give you a clue:
try www.afteridie.org

and you will be able to leave a mark too!

Color Picker

Friday, August 29, 2008 4:52:18 AM

color picker userscript

Get last version!: get_color.js

Sometimes you want to get the color of some part of a web page. Here you can see my script called Color Picker
This is an example:

This is the example code:

<style type="text/css">
h1 {
	color: #ffff00;
	background: #ffdddd;
	border:3px solid;
	border-bottom-color:#0000FF;
	border-left-color:#00CC00;
	border-right-color:#FF0000;
	border-top-color:transparent;
}
</style>
<body>
<h1 id="h1">
<p style="color:#00ccff;">hello I'm a <p> tag into a <h1> tag</p>
</h1>
</body>

and this is what you get from my script
First, click over P object:

Second, click out P but inside H1 object

as you can see there is a <p> tag into a <h1> tag, and <p> has no background, but it don't care, what you want to know is the background color that you are seeing. so if some element has transparent background the code check parentNodes until get some color background.

another thing is that you have the four borders, as you can see in the last picture, you can click over each little part to get the hexadecimal values.

Finally, how to use?
First of all, you have to click over the object you want, but maybe it's a link... so:
1. You have to just drop the mouse over the object. (Don't care where you clicked first)
2. Then you have to execute cp_getColor() function. So, you can put a button or some item into a context menu, like this:

Item, "Color Picker"="Go to Page,"javascript:cp_getColor()""

If you have inserted it into a context menu, you can right-click over anything, because Opera doesn't allow to check right-buttons events.

showModalDialog for Opera

Thursday, August 7, 2008 10:59:08 PM

modal, window, userjs, showmodaldialog

Last release v1.1
Compressed version here

May be you clic in some element in a web site and nothing happen, but if you try in IE or FF it works fine, and a new window opens. The problem is because in the code there is a modal window, and Opera doesn't support it.

function showModalDialog() was implemented for MSIE. Now FF is compatible, but Opera not yet.
Because of that I've made this script.
If the page want to show us a modal window, a confirm message box appears:

For a Modal Window emulation we've to click 'OK'

Otherwise, just 'Cancel' and a new window is opened

clic here to see the example

UV map for objects in canvas 3d

Thursday, July 24, 2008 7:49:31 PM

canvas 3d

I've just finished the new version of ase2opera (I think in the future I will call it ase2xml...)
So here are the steps to make a correct transform:

Step1: Apply to each object in 3DMax an UVW planar map, be sure you put 0 in W value.

Step2: Export each object as .ASE file one by one, with these options

Step3: Transform your .ase file into a .xml file with my ase2opera utility.

Step4: Add textures and objects! you can see an example here.

This is the difference between Opera Canvas...

...and 3DMax

... just the background!

so, what's next? I have two new ideas in my mind, I want to transform a camera path to make animations more flexibles, and in a far future, a game like pac-man in first person mode...

First, you have to export a selected object as ASCII file:

then you have to make sure just these check boxes are marked:

finally you have to enter to my php ase2opera converter, upload your .ase file and get your .xml file

here is a teatpot example:

as you can see I don't made a good algorithm for u,v map coordinates... so I need somebody help...
