...that it is more flexible about its use of colors. I have added a new parameter to the X11/x11 function which controls this. The parameter is currently called "colormodel" and works as follows: colormodel = 0 Monochrome graphics colormodel = 1 Grayscale (256 shades) colormodel = 2 Pseudocolor1 colormodel = 3 Pseudocolor2 colormodel = 4 Truecolor Pseudocolor1 allocates as big a color cube as possible and then approximates requested colors with colors from the cube. Pseudocolor2 allocates colors "on-demand" until it runs out of colors. You then get a "can't alloc...

(verified with xwininfo) Note that the help page does *not* say that this `selects a visual'. It says it selects a `color model'. One can use a model which differs from the X11 visual class, but the default class and depth are always used. This seems to be a m...

I've writen this function (imagenrgb) to display a (m,n,3) array as a RGB image with ngris^3 colors and,optionally, stretching. If option ver=F, it does not display but saves a pseudocolor version of the image as a list (so that subsequent displays are faster). I'd appreciate feedback and improvements and hope that it's useful for others. Example of use: > dim(imatest) [1] 100 400 3 > imagenrgb(imatest) > imagenrgb(imatest,ngris=16,stretch="l") >...

for some reason the following message seems not to have reached the list in the first try, at least I can't find it. my apologies if this is my fault: we are running R under Solaris with SunRay Terminals, which are set to 8 bit color to comply with some other software. In this configuration, X11() opens with colortype=true, i.e., it is not recognized that actually the display is only 8

The xstdcmap utility can be used to selectively define standard colormap properties. It is intended to be run from a user's X startup script to create standard colormap definitions in order to facilitate sharing of scarce colormap resources among clients using PseudoColor visuals.

...nor bug fixes since 2.4.0. We now refuse to run on machines with UEFI firmware (on Linux only, patches welcome for other OSes) since it won't work in the general case and you probably have a kernel framebuffer driver running already. We also only attempt to use 24bpp if the alternative would be pseudocolor, but note that since xserver 1.20 24bpp will not work at all. If you'd like to fix that case, please note that it is filed as issue #4: https://gitlab.freedesktop.org/xorg/driver/xf86-video-vesa/-/issues/4 We also notice several cases of running on emulated GPUs, in which case the shadow fram...

I'm trying to run an old (~1995) Windows game under Wine, but it requires 256 colours and won't work any higher. I've checked out the 256 colour hacks page and the X methods don't work, because I use the FGLRX drivers and they don't support 8bpp, so I'm trying VNC. I've installed vnc-server and vnc so I can play it through a 256 colour VNC connection, but so far I can

I've fixed the original report and Tom's first. Someone had incorrrectly arranged for most of the initialization to be done only once per session. I did ask before 1.3.0 what the intention was .... For pseudocolor devices at least this was biting since the palette was not re-initialized. I don't see point two on my system, and Martin's point about interruption was first shown to me by Guido a year ago, so is unrelated. I am going to close this topic: Tom and Martin feel free to re-submit your repor...

...yet. o HDF5 support improved. Still not perfect, though. o The X11 graphics driver can now use a variety of strategies for handing color. This means that it is now possible to use black and white or grayscale graphics on color displays. There are two strategies for handing color on pseudocolor displays. The original "allocate-colors-until-they-run-out" strategy has been supplemented by one which allocates a color cube at startup and approximates requested colors by those in the cube. On truecolor displays, there is no limit on the number of colors which can be displayed...

Hi! While trying to get CLUT support for the atmel_hlcdc driver, and specifically for the emulated fbdev interface, I received some push-back that my feeble in-driver attempts should be solved by the core. This is my attempt to do it right. I have obviously not tested all of this with more than a compile, but patches 1 and 3 are enough to make the atmel-hlcdc driver do what I need (when patched
