I'm having a problem figuring out how the Flood() function works. I've
been able to get flood mode #0 (flood to the outline color) to work, but
it's incredibly slow (even on my 3000), and not really what I want anyway.
Mode #1 (flood the block of color at the given coordinates), on the other
hand, looks like it will fit the bill, but I haven't been able to get it to
work. Here's a code sample that illustrates what I'm trying to do
(ignoring the fact that this could be done with RectFill or AreaInfo):
#include <exec/types.h>
#include <intuition/intuition.h>
struct NewWindow NW =
{0,0,300,200,-1,-1,NULL,WINDOWDRAG,NULL,NULL,"Window",NULL,NULL,
0,0,640,400,WBENCHSCREEN};
struct Library *IntuitionBase,*GfxBase;
struct Window *wdw;
#define Rp wdw->RPort
main()
{
/*Open libraries*/
IntuitionBase=(struct Library *)OpenLibrary("intuition.library",0L);
GfxBase=(struct Library *)OpenLibrary("graphics.library",0L);
wdw=(struct Window *)OpenWindow(&NW); /*Open window*/
if(wdw==NULL) /*Exit if not opened*/
exit(1000);
SetDrMd(Rp,JAM1); /*Set drawing mode and pen*/
SetAPen(Rp,1);
Move(Rp,15,20); /*Create a box from (15,20) to (100,100)*/
Draw(Rp,15,100);
Draw(Rp,100,100);
Draw(Rp,100,20);
Draw(Rp,15,20);
Flood(wdw->RPort,1,30,30); /*And fill it (but it doesn't work!)*/
Delay(100); /*Pause for a bit...*/
CloseWindow(wdw); /*Cleanup and exit*/
exit(0);
}
I'd appreciate it if someone could point out what I'm missing. Thanks.

Here's a code sample that illustrates what I'm trying to do You need to allocate a TmpRas, and set the TmpRas pointer of the rastport to that. The TmpRas (presumably short for temporary rastport) is the same height and width as your window's rastport, but only one bit-plane deep. Check the RKM for more info, as I can't remember exactly how its done of the top of my head. Jon -- | Jonathan Potter | | I'd really like to | | P.O.

I tried your suggestion, and it Flood() still doesn't work (at least not mode 1; mode 0 works perfectly without a TmpRas). I can't find anything in the (1.1) RKMs, BTW, about using a TmpRas with the Flood() command. Is it in the 1.3 RKMs? >| Jonathan Potter | | I'd really like to | -- Dave Schreiber E-mail: davids@ucscf.ucsc.edu "It was fun learning about logic, but I don't see where or when I will ever use it again."

Is it in the 1.3 RKMs? You're right, I can't find anything in the 1.1 rkms either (tho I'm sure it was there :-) However, try page 369 of the 1.3 libraries & devices.
