Graphics Devices and Cprintf clash

Hi,

** I am using Turbo C Version 2.01 (DOS)

Currently i am working with a program that uses the graphics device to use certain functions like line(); etc. This uses the "graphics.h" header file.

I find that when i attempt to use the "cprintf" function it doesn't work. In fact, it only works when there is no graphics initialisation or when the closegraph(); function is used, but this takes away all the line functions i just made.

My question is: Is there a way to use the graphics device, keeping all your line functions on the screen, while using cprintf function.


Here is the code i am using to initialise my graphics device:

Code:

---


        /* Initialising Graphics Drivers */
        /* request auto detection */
        int gdriver = DETECT, gmode, errorcode;

        /* 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 */
            }

        /* End of Initialising Graphics Drivers */

Thanks for reading.

For outputting text in Graphics mode, use

outtext("string"); or
outtextxy(x,y,"string");

Sure, outtext will display text. as will printf.

however, i need my text to be in colour, which is the essence of my problem.

Thanks for your time,

Sure...

You have the functions

setcolor(int color);
and
setbkcolor(int color);

which set the foreground and background colors. You can also change the font and its size using settextstyle(...).

I feel you should go through a complete graphics tutorial before.

Sorry to bother you again, however i have gone through the help files regarding graphics.h and cannot find a way to print out a variable.. only strings are possible.

basically i need to emulate the printf function in graphics mode.

eg, how would you do "printf ("%d", Variable); in graphics mode?

thanks again,

>cannot find a way to print out a variable.. only strings are possible.
So use strings. Take a look at the sprintf function, you can place any variable in a string and then use outtextxy or outtext to print it to the screen. As you can probably imagine, this gives you quite a fine degree of control.

-Prelude

i agree to that prelude
