I created this bat file for Windows users.
Program only tested on the Windows XP 32 bit platform.You need to have image magick installed.

Any PNG Perspective Transformer.

You can unzip the bat and image file here - C:\Make_Perspective. (create the Make_Perspective folder)
Any PNG image you want to transform rename it to 1.png and drag and drop it on the bat file
the image will be transformed and saved as 1_pers.png in YOUR user directory.
Now just rename the file and your good to go.
Transform this

I am trying to get this to work in Shellout but i am having some difficulty Rob. :\
Any idea how i would fix the bat code to work in Shellout?



My Shellout code

The old Perspective Reflection script still works in Gimp-2.8!
I did not realize that.
http://registry.gimp.org/node/15784

maybe is possible use also this http://www.sb-software.com/nonlinear/index.html with shell out ?

it is quite old and not much known but is a very good tool

(it should even be possible emulate in gmic, once David even explain me how in theory, but i had not sufficient patience to code it )

PS on the site you will also see "purchase" and "register", but is donation-ware: you may try as long you wish, it never expire, but ifif you like the author invite you to register (in case using the "contact" link because the register link is broken)

Thanks PC.I have this program already and it doesn't create perspective transforms.Only warping effects on a square or rectangle.
I also tried Inkscape by opening the image in Inkscape through shellout and doing an object to pattern.But that didn't export back into Gimp very well.It was a plain white image.
I will keep trying to get this bat file to work in Shellout i guess.
The reflective perspective script works ok but i wanted something that only warps the image and does it the same every time.
HeathenX (where i got the idea from), has this tutorial for Ubuntu operating systems. I wanted to get it working in Windows.Which i was able to do, but i would like to be able to export it through shellout to the bat file and back into Gimp.I just don't know how to script the proper code for that.

If i could find an open source program for windows that would do this type of perspective transformation that would be pretty cool.Then i could just call the program through shellout as normal.

Have you tried GMIC, Artistic, Reflection?
Just set the Height to "0".

Is there any way to get the edges less jaggy without cropping?

I just used the Perspective tool on this one.
