#774: i.rgb.his, i.his.rgb, d.his support for >8 bit --------------------------+------------------------------------------------- Reporter: hamish | Owner: [email protected] Type: enhancement | Status: new Priority: normal | Milestone: 6.5.0 Component: Raster | Version: svn-develbranch6 Resolution: | Keywords: i.rgb.his, i.his.rgb, d.his Platform: All | Cpu: All --------------------------+------------------------------------------------- Comment (by hamish):
updated patch attached allowing >8 bit support for i.rgb.his and i.his.rgb. Patch is against latest 6.5svn. Note round-trip is a little lossy due to hexagonal approximation to the color-cone. TODO: use real cone geometry maths. These modules write out colr/ tables as min,max of channel. Would it be better to write them out as 0,max_level for the particular bit-depth? e.g. 0,255 for 8-bit and 0,2047 for 11-bit. Then d.rgb and d.his give natural looking results without subtle extra steps. Hamish -- Ticket URL: <https://trac.osgeo.org/grass/ticket/774#comment:3> GRASS GIS <http://grass.osgeo.org>
