NAME
vga_getpalvec - gets colors from the color lookup table SYNOPSIS
#include <vga.h> int vga_getpalvec(int start, int num, int *pal); DESCRIPTION
Gets the num colors starting with index start from the color lookup table and stores the RGB values in *pal. *pal contains 3 * num integers which are the color values from first to last palette entry in the order red, green, blue (always three consecutive entries in *pal built a palette entry. Each color entry is in range 0 - 63. This function is only sensible in 16 or 256 color modes. It shows which color all vga_setcolor(start) (and num - 1 following colors) drawn pixels will actually refer to. If the VGA_CLUT8 feature is set for the current mode with vga_ext_set(3) the red, green, and blue values are in the range 0 - 255. The function returns the value of num. SEE ALSO

NAME
restorepalette - set the color palette for textmode. SYNOPSIS
restorepalette [filename] DESCRIPTION
restorepalette without arguments sets the standard VGA palette. This can be useful if it is somehow messed up. With a filename argument a custom palette can be loaded (feature added by Charles Blake <chuckb@alice.wonderland.caltech.edu>). This allow a user to set up a file that looks like this one (These color map definitions are the same as the default VGA ones. Alter to suite personal tastes). The first column contains the number of the color to set, then follow three integers in range 0 - 63 (lowest to highest intensity) for red, green, blue. 0 0 0 0 # black 1 0 0 42 # blue 2 0 42 0 # green 3 0 42 42 # cyan 4 42 0 0 # red 5 42 0 42 # magenta 6 42 21 0 # brown 7 42 42 42 # white 8 21 21 21 # bright black 9 21 21 63 # bright blue 10 21 63 21 # bright green 11 21 63 63 # bright cyan 12 63 21 21 # bright red 13 63 21 63 # bright magenta 14 63 63 21 # bright brown 15 63 63 63 # bright white The inline comments are the only kind of allowed, as I use a little fscanf(3) trick to get them. Blank lines are ok, but not pure comment lines. See the comments in my code, also. This allows people to set up custom palettes for use in virtual console text modes. I use it all the time. When combined with a color-syn- tax editor like jed-0.97+ or color-ls, etc., being able to choose your own text-mode palette is quite a bonus. I set mine up via restorepalette /etc/palette in my /etc/rc. If the program is given the correct permissions, then individual users can have restorepalette ~/.palette or some such thing in their shell startup files. Of course, it shouldn't be done when starting remote shells or when under X, so some kind of test that TERM is a virtual console is needed for that case. SEE ALSO
