Bending an image into a perfect circle

Recommended Posts

Hello everyone! English is not my native language so sorry for the mistakes. 

I want to bend a 88 key piano image into a circle, I need the circle for a project, all the images that I've found have a wrong disposition, I have attached two images, the first is an example of the image I want to bend (is a better res image but like this one), the second is the result I want to get but the keys are wrong as in all the rest. 

I really am not proficient with design programs, is there any way I can bend this image into a perfect circle? Thanks in advance.

Hi @Adrián

Welcome to the forum

Ensure your image is on a square canvas large enough to support the size of your circle (1000 X 1000), then try this pugin;

It will get your image into a perfect circle but you may have to edit your source image to get the keys lined up correctly.

Any more questions just ask :)

Further to what Andrew David said you'll have to flip your keys vertically (Image >>> Flip Vertically) otherwise the ebony ones will be on the inside not the outside

It turns into a math problem when you want just the 88 keys in the finished circle. Size of the keys and the size of the canvas determines success. Note how the pattern is always 3 Black followed by 2 black keys without changing the pattern. Took about an hour to figure it out :)

Thank you very much! Is the effect I was looking for.

I like the Polar Transformation effect :)

Your image is fantastic! Just missing 1 key, the high C, otherwise would be exactly what I want, I'll try to use Andrew's method and post the result!

Nooo haha that's what's wrong with all the images I've found, a full piano has 88 keys, organized in 7 octaves, or sets of 12 (from C to the next C), of this sets 7 keys are white and 5 are black, the black ones being in that 2/3/2/3 pattern, but you still have 4 more keys, A, A# and B on the low end before the first C, and another C on the top, Making it 88 keys, like the linear piano I sent in my first post. 

Treating this mathematically is far beyond my capabilities, but I'll try the first method you suggested, thank you!

The late great jazz pianist Oscar Peterson sometimes played a Bösendorfer piano that had 97 keys.
