jit.gl.pix sample object - rotation squeezes the texture

Hello jitter pros,

I am writing my first jit.gl.pix objects and have a question about rotating a texture.
I found this great rotation patch here, but the rotation squeezes the texture like videoplane (@transform_reset 2)

The jit.gl.slab @file td.rota.jxs object works, but makes the background black and i want to stay in gen if possible.

Perhaps someone has a hint for me.
Here is the patch.

All the best,
Penelope

I think it's because of the aspect-ratio of your sourcefile because it has to fit the horizontal 1920 pixels into the vertical 1280 pixels and vice versa. There's no distortion if you use a square matrix

Hi,

Luvulongtime is correct; you have to compensate for the aspect ratio before and after applying the rotation:

Hello luvulongtime and Matteo Marson,

thank you so much for your help!
At the end things are looking so easy ;-)

Have a nice day,

Hello jitter fellows,

I just want to give something back.
A jit.gl.pix rotator with scale, position and boundmode adjustments.

perhaps useful for someone who do not reinvent the wheel ;-)

Happy patching,
Pelo
