I dont know if I'm understanding well .. What I want is this: "Building a colormap containing 256 colors is quite a chore, but the ColorUtils library (http://code.google.com/p/colorutils/) can generate several predefined maps. Figure 20 employs the colormap returned by ColorUtils.getSpectrum(), which colorizes the white to black range *using the red-to-violet spectrum*. This means that objects in the depth map close to the Kinect will be rendered *red or orange*, while those further away will be *green, blue, or violet*. Those without depth measures (perhaps because they are too close to the Kinect) will be rendered as red."
(the example I took from pdf is in JAVA) It says values near (the first values) are red or orange and the values far (the last values) will be green, blue or violet. By near and far, I mean the iterations of i (0 to 255) 2012/7/13 Christopher Night <[email protected]> > According to Wikipedia, violet is (127, 0, 255), so this should work: > > tuple((255-(i+1)//2, 0, i) for i in range(256)) > > -Christopher > > > On Fri, Jul 13, 2012 at 12:20 PM, Ricardo Franco > <[email protected]>wrote: > >> I would like to know how to build a specifc color palette, its the >> red-to-violet color palette. >> To build the grayscale color palette I use: >> >> grayscale_palette = tuple([(i, i, i) for i in range(256)]) >> >> How do to get the red-to-violet color palette? >> >> -- >> Ricardo Franco Andrade @ricardokrieg >> >> ( Game | Desktop | Web ) Developer >> >> email: [email protected] >> contact: +55 (86) 9958 9725 >> +55 (86) 9436 0830 >> twitter: twitter.com/ricardokrieg >> facebooK: https://www.facebook.com/krieg.ricardo >> github: https://github.com/ricardokrieg >> >> > -- Ricardo Franco Andrade @ricardokrieg ( Game | Desktop | Web ) Developer email: [email protected] contact: +55 (86) 9958 9725 +55 (86) 9436 0830 twitter: twitter.com/ricardokrieg facebooK: https://www.facebook.com/krieg.ricardo github: https://github.com/ricardokrieg
