Avisynth - image to rotating animation

[maudit]

Hi, I'd like to create a GIF form a single image.
The source is a PNG with transparency.

The code I put in Avspmod

ImageSource("C:\Users\antip\Desktop\yy\Yin and yang.png")

Spline36Resize(64,64)
Loop(0,360,1000) # or Trim(0,359)
ConvertToRGB32()
Rotate(endangle=359)

It works but how to keep tansparency? Can I write it in some other better way?

I could create the GIF using ffmpeg, but can I in another way?
I thought in could encode the script in a mkv, then export all the images in a sequence and re assembly them in vdub2 exporting as a GIF or APNG, but I'm quite sure vdub can't handle transparency.
Any other better suggestion, please?

pixel_type="RGB32" to load the alpha channel

ImageSource("C:\Users\antip\Desktop\yy\Yin and yang.png", pixel_type="RGB32" )
