Couple of image suggestions
 

1) I've suggested it before but I'd still like to see it happen: allowing negative input to stretchx/y. This would flip the image when under 0. So stretchy=-1 would be a vertical flip of an image. Right now there is rotating of images, but no flipping. Why not?
2) changeimgvis also allowing negative input. This would show images under the tileset. Please... pretty please?

3) not a suggestion, but a bug of sorts. Rotating any gani, whether it be a player object or showimg object, will distort its position. This is not apparent on gani's such as idle, walk, push and such, but try rotating a gani and setting it as sword. Its position gets all screwed up.

You can already do this with guis.

Ya I know... you should know I know, you taught me! :P
I'm talking in relation to level coordinates though.

Ganis are rotating around their center (1.5, 2) I think

Is it possible to change the anchor position of a GANI or image?

That's a great idea.

Maybe something like:

NPC Code:

---

centerrelative - Where the relative center of the image is based on the width and height.  Default is {0.5, 0.5}.

centeroffset - Pixel offset from the relative center that is regardless of image width and height.  Default is {0, 0}.

---

So if you wanted it to always rotate around its lower left corner you could just do:
If you wanted to rotate 16 pixels down and right from the upper left, you could just do:
