===== setallpalette ===== ====Syntax of setallpalette ==== #include void setallpalette(struct palettetype *palette); ==== Description of setallpalette ==== setallpalette sets the current palette to the values given in the palettetype structure pointed to by palette. You can partially (or completely) change the colors in the EGA/VGA palette with setallpalette. The MAXCOLORS constant and the palettetype structure used by setallpalette are defined in graphics.h as follows: #define MAXCOLORS 15 struct palettetype { unsigned char size; signed char colors[MAXCOLORS + 1]; }; size gives the number of colors in the palette for the current graphics driver in the current mode. colors is an array of size bytes containing the actual raw color numbers for each entry in the palette. If an element of colors is -1, the palette color for that entry is not changed. The elements in the colors array used by setallpalette can be represented by symbolic constants which are defined in graphics.h. See Actual Color Table given here: Name Value BLACK0 BLUE 1 GREEN2 CYAN 3 RED 4 MAGENTA 5 BROWN6 LIGHTGRAY 7 DARKGRAY 8 LIGHTBLUE 9 LIGHTGREEN 10 LIGHTCYAN 11 LIGHTRED 12 LIGHTMAGENTA 13 YELLOW 14 WHITE15 EGA_BROWN 20 EGA_DARKGRAY 56 EGA_LIGHTBLUE 57 EGA_LIGHTGREEN 58 EGA_LIGHTCYAN 59 EGA_LIGHTRED 60 EGA_LIGHTMAGENTA 61 EGA_YELLOW 62 EGA_WHITE 63 Changes made to the palette are seen immediately onscreen. Each time a palette color is changed, all occurrences of that color onscreen change to the new color value. Note: Valid colors depend on the current graphics driver and current graphics mode. setallpalette cannot be used with the IBM-8514 driver. ==== Example of setallpalette ==== See also _getpalette_ _getpalettesize_ _graphresult_ _setbkcolor_ _setcolor_ _setpalette_ ==== Example of setallpalette ==== /* setallpalette example */ #include #include #include #include int main(void) { /* request autodetection */ int gdriver = DETECT, gmode, errorcode; struct palettetype pal; int color, maxcolor, ht; int y = 10; char msg[80]; /* initialize graphics and local variables */ initgraph(&gdriver, &gmode, ""); /* read result of initialization */ errorcode = graphresult(); if (errorcode != grOk) /* an error occurred */ { printf("Graphics error: %s\n", grapherrormsg(errorcode)); printf("Press any key to halt:"); getch(); exit(1); /* terminate with an error code */ } maxcolor = getmaxcolor(); ht = 2 * textheight("W"); /* grab a copy of the palette */ getpalette(&pal); /* display the default palette colors */ for (color=1; color<=maxcolor; color++) { setcolor(color); sprintf(msg, "Color: %d", color); outtextxy(1, y, msg); y += ht; } /* wait for a key */ getch(); /* black out the colors one by one */ for (color=1; color<=maxcolor; color++) { setpalette(color, BLACK); getch(); } /* restore the palette colors */ setallpalette(&pal); /* clean up */ getch(); closegraph(); return 0; } ==== See also ==== [[getpalette]] [[getpalettesize]] [[graphresult]] [[setbkcolor]] [[setcolor]] [[setpalette]] ==== See also ==== [[_getpalette_]] [[_getpalettesize_]] [[_graphresult_]] [[_setbkcolor_]] [[_setcolor_]] [[_setpalette_]] ===== output of setallpalette example ===== no output of example at the moment do not hesitate and add it...
