We can adjust the width and height of the image e.g. (‘autumn’)

Is there a way to show a part (selected coords only) of an image on uicontrols using html code?

Thanks

Excellent decision Yair !
Thanks!

I plan an extensive exposé on functionSignatures.json in the upcoming weeks. Stay tuned 🙂

To be truthful, I have it in the works for several months already. But with R2016b officially out, and you having outed these files, it’s about time for me to close this corner. This is a great feature that is still undocumented, so it’s a perfect match for this blog.

With R2016b, you can use built-in function jsondecode.
Oddly enough, some .json files in matlabroot are not valid JSON files: some contain comments and others have duplicate keys.

One possible solution to get the list of builtin colormaps would be to parse in R2016b the functionSignatures.json under matlabroot\toolbox\matlab\graph3d and to use loadjson from https://www.mathworks.com/matlabcentral/fileexchange/33381-jsonlab–a-toolbox-to-encode-decode-json-files

r = loadjson('functionSignatures.json')
choices = r.colormap.inputs{1,2}.type{1,1}{1}

which would return

choices = {'parula','jet','hsv','hot','cool','spring','summer','autumn','winter','gray','bone','copper','pink','lines','colorcube','prism','flag','white','default'}

It was just a sidenote 😉

Could you dedicate a post about using `image()` and `imagesc()` an assuring 1:1 (100%) zoom level of an image?
I know there is `imshow()` but what if one would like to use low level functions.
Moreover, since the ‘Unit’ ‘pixel’ isn’t a pixel anymore, it might be tricky.

Thank You.
