3562.0. "Firefox Color Problem" by TAV02::MELVYN (Why did I learn Computers ?) Thu Nov 01 1990 04:45

Dear All,

I have a customer who has a Firefox with 8 planes. He is having trouble
allocating certain colors.

The following code returns to him for both color "red" and "cyan" a color 
pixel value of 10.

The RGB values however are returned from the parser correctly.

# include <stdio.h>
#include <decw$include/DwtAppl.h>
#define num_colors 2
main(argc,argv)
int argc; char argv[];

{
	Display *display;
	char *color_name[]={"red","cyan"};
	XColor color;
	int i;

	display=XOpenDisplay(NULL);

	for (i=0; i<num_colors; i++){
	 XParseColor(display,
		        DefaultColormap(display,DefaultScreen(display)),
		        color_name[i],
			&color);
	printf("color is %s \n",color_name[i]);
	printf("color.red %d \n",color.red);
	printf("color.green %d \n",color.green);	
	printf("color.blue %d \n",color.blue);

	if (!XAllocColor(display,
	                DefaultColormap(display,DefaultScreen(display)),
		        &color)) {
			printf("oops \n"); }
	printf("color.pixel %ld \n",color.pixel);
	printf("****************************************************\n");

                                                                }
}
I would appreciate any ideas. Cross posted in Firefox and Decwindows.

Thanks 

Mel

It works fine on a GPX and an SPX.  I don't happen to have an 8-plane ff,
though.  I suggest a QAR.
