[How polar inversion works ?]

Finaly i found a way faster way to do it xD I use some of my hacker skill to inject a "multiply by 8" in the code to do what i wanted.

Merci bien pour cette réponse rapide, je vais essayer CodeLab

[How polar inversion works ?]

Hi, i'm wondering how polar inversion works. is Paint.net setting the r coordonate with the x and set ϕ to y (eg: A (x, y) -> A' (1/x, y). I don't know where the inversion goes, but i'm 90% sure the effect invert the "r coordonate" cause the center is infinite. Also i don't know what the "quantity parameter" do

I want to reproduce the effect with python to modify some things cause i want another result (like increasing quantity to -10 or more)

 

Thanks for reading

[Video/GIF of an image with polar inversion]

I didn't find something on google about polar inversion.

 

 

I "prit mon mal en patience" and i rendered 90 frames of 2560 * 1440. 30 frames left :/.

I founded a C/C++ librairy to edit and save images. I just need the exact formula of the polar inversion (either reflect or either warp mode)

[Video/GIF of an image with polar inversion]

I'm not making screen shot ? I'm going to calculate a reasonable rate for having a fluid animation without losing quality.

 

How does the polar inversion work ?

 

I wonder : translate coordonate in polar coordonates.

Remplace all the pixel by the (1/x) th one.

Translate new image from polar to orthogonal 

 

I'm i right ? 

[Video/GIF of an image with polar inversion]

I talk about gif but just want a nice, big and fluid animation. it is 4000x2000, and i want at least 40fps during 3sec. I think i will do 120 images.

 

I downloaded IrfranView, but how could it help me ?

[Video/GIF of an image with polar inversion]

Sorry, my code should be 0.01 instead of 0.1

[Video/GIF of an image with polar inversion]

300 images by hand :..(

No way to code an effects.

 

At least how do this effect work (maybe coding python to reproduce the effect)

[Video/GIF of an image with polar inversion]

Do you know any software that could do that ?

[Video/GIF of an image with polar inversion]

I want to make a video or a gif about an image. I want my image to be gradually twisted with the "polar inversion". How to make an algorithm like this :

float i = 0;
while( i != 4)
{
	apply Polar Inversion (Quantity : i);
	save image as "MyImage"+i+".png";
	revert to the original image;
	i = i + 0.1
}

how to do this automaticly?

Damn i already have this effect ! I already downloaded this pack. I need to check my eyes

Thank you anyway ;)

[Apply the alpha from an image to another]

I have a white image with some shade of alpha.

I have another image with is colored (eg : a photograph)

I want to apply the alpha from the first image to the other

Sounds easy but i didn't found how to do it

Thank you for your aswer

[How can i use an image like a green screen]

I have a empty card and another one with some test on. I just want to keep the text and delete everything twice :

http://krosmaster.herazade.com/HG/img/front.png -> empty

http://afranchcoder.comuf.com/files/Sandy.png -> full

How can i do it?

Ok merci beaucoup pour ta réponse rapide.

Je te parle français car je suis français et que tu a l'air de l'être aussi (a moi que tu kiff le chat noir sans etre francais)

Je peux creer et sauvegarder une image tout seul, ce n'est pas le plus embêtant. 

Merci beaucoup en tout cas pour script lab, c'est exactement ce que je cherchait

 

Just in case you re not french :

OK thank you very much for your fast answer.

I can create and save my image by miself, it is not most annoying. 
Thank you for script lab, it is exactly what I was looking for

 

[How to make algorythmes/bots]

How can i made a bot that do some thing for me like :

Make me a new image by 70x61p

Fill it with red

Apply noises (with 15 as fisrt parameter , 23 as ....)

Draw a rectangle at 0,0 with a weight of 10 and a height of 28

Save it sa .png file on my desktop

....

 

Is there any program to do it ?

Or must i use a program that record my keyboard and my mouse mouvement and redo it ?
