I'd like to import an image, superimpose it, reduce the opacity of the overlaid image, and then use a manipulate to rotate the top image to illustrate rotational symmetry.
The image below is using image editing software, not Mathematica, but illustrates the effect I am after.
There are many nice images on the net that could be used to illustrate this concept. Can this be done using Mathematica and the image processing commands?
I tried importing an image file, then used Show
and ImageRotate
for example,
g1 = Import[ graphic....]
Show [ g1, ImageRotate[g1, pi/4]]
but that wasn't at all what I was looking for...
I'd appreciate any suggestions for commands that could achieve this effect.
My goal would be to create several Manipulate
s with various images to illustrate various orders of symmetry with image files (I've already done this with line drawings).
Some related hopefully useful images:
