Ebook plugin

[jumpjack]

I'd like to write a plugin which distort images like this to make them appear as if the book was totally open:

Books I scan CANNOT be totally open when taking the picture they would get damaged.

Is that possible?
Shouold I write a plugin or a script?
Where can I find informations I need?

Everything is possible if it's just about manipulating pixels ;-)

Sorry for the question but do you have an idea about the required math?

[jumpjack]

Yes, that's why I'd like to know if IrfanView can simplify the process, rather than thinking&writing the algorithm from scratch!

Maybe ImageMagick is more suitable, with dzens of commandline options?

I wonder which is the english verb which describes what I'd like to do...

[impdf]

Irfanview is a pixel based viewer with some addons.

You will need vectors and splines maybe you can write an add-on for InkScape.

Google did something like this but I do not know if they published the algorithms.

Or have a look to morphing.

What about this ImageMagick option?

I have tu transform a 6-points polygon into a rectangle.

No idea about Imagic Magic.

But I guess a polygon transformation is too simple to get good results.
