High Color and TrueColor

# 6 High Color and TrueColor

Contents of this section

Support for 16 and 24 bit truecolor is now supported. Note that 24 bit color is really 32 bits per pixel. Use the `-bpp` option when starting the server. Examples:

            startx -- -bpp 32
            startx -- -bpp 16
            startx -- -bpp 16 -weight 555
            startx -- -bpp 16 -weight 565

Note that many programs do not yet work properly with these modes. Don't tell me. Tell the authors unless they've already fixed it. It's their fault… :-)

Example problems:

xv 3.00

  Works fine in 32 bpp and in 16 bpp with 24 bit images. Has problems with colors in 8 bit images in 8 bpp mode.

Mosaic 2.1

  Has problems with colormap in both 16 bpp and 32 bpp. Newer versions of Mosaic such as 2.4 do work.

mpeg_play

  Doesn't work at all in 16 bpp mode. Works fine 24 bpp mode when compiled with -DRS6000 and when run with ```-dither color`''

xpaint 2.1

  Works great in both modes but has a bug in the color requester for the selection tool. I think later versions may have fixed this.
