Video/GIF of an image with polar inversion

[MisterAqua]

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?

Correct code

Paint.net cannot be automated in this way.

[MisterAqua]

Do you know any software that could do that ?

[Ego Eram Reputo]

Sorry, no.

 

If I was doing this I'd bite the bullet and do it manually.

[MisterAqua]

300 images by hand :..(

No way to code an effects.

 

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

[MadJik]

 Reading your code I count 40 images.

For my gif I use a screenshot capture. It saves each frames with a number...

 

[MisterAqua]

Sorry, my code should be 0.01 instead of 0.1

[MadJik]

Then you understand that @Ego Eram Reputo could suggest to do it manually for "only" 40 slides.

 

Still I count now 400 images to handle with. Have you already use an animated gif program with as much as 400 images?

 

What is the size of 1 single image in pixel ? x400 ?

Have you tried Irfanview?

[MisterAqua]

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 ?

[MadJik]

4000x2000 you should forget about screenshots if you don't have a screen with that resolution!

 

[MisterAqua]

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 ? 

[MisterAqua]

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)

[Ego Eram Reputo]

Google it.

[MisterAqua]

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 :/.
