BTW. Got the pie charting stuff working thanks to the AreaFill example.

Thanks Thomas.

That's OK. I had assumed that. I might go for a few more points though as 10 degrees might have edges that are too long and straight, but we'll see.

Oh yes, definitely. Flood was always my last option but I had it in my head that the area functions wouldn't work. Happily, I was wrong.

Thanks Thomas.

@broadblues

Hmm. I get the same weird result in an 8-bit screen. I guess there is a bug.

Unfortunately I can't use AreaFill() because I'm filling a pie chart slice which has an arc. I guess I'll have to do my own floodfill as a workaround until it's fixed.

Thanks.

Actually, the real project uses AllocRaster(). I was just experimenting in my example, but your tips are appreciated and I really should be using GetBitMapAttr() which I wasn't before, so thanks for that too.

Thanks thomas and broadblues for having a look.

Firstly, I didn't realise it was the screen's rastport. I thought it was the window, so that is a definite issue. Thanks for the correction thomas.

Actually, the real program I am writing is on OS4, I just thought I would go back to a simpler example and build it up from there once it works.

On the real program I end up with the whole window being filled with corrupted rubbish when I try to floodfill. I know that what I am filling is fully enclosed. Maybe it is a 16/32 bit screen issue. I will try a few scenarios and have a look.

Cheers!

Using Flood()

Posted on: 2012/1/7 7:10 #68

Hi all,
This might sound a bit stupid, but I've been able to most things when programming the Amiga, but flood fill isn't one of them. I have always been missing something but cannot work out what it is. Now, I really need to do it for a project I am working on and it still doesn't work.

I've knocked up a quick example to see if I could get it working but even the small example doesn't work. It's meant to draw a circle and fill it. Should be easy, right? The circle draws fine, but no fill happens. Can anyone see what I am doing wrong?

Example code below, compiled with SAS/C 6.x and run/tested on AmigaOS 4.1.4:


/* Attempt to test flood fill */

#include <exec/types.h>

#include <graphics/gfx.h>

#include <graphics/gfxmacros.h>

#include <intuition/intuition.h>



#include <proto/exec.h>

#include <proto/dos.h>

#include <proto/graphics.h>

#include <proto/intuition.h>



#include <stdlib.h>

#include <stdio.h>



int main(int argc, char *argv[])

{

    struct Window *win;



    win = OpenWindowTags(NULL,

                         WA_InnerWidth,    200,

                         WA_InnerHeight,   200,

                         WA_IDCMP,         IDCMP_CLOSEWINDOW,

                         WA_Title,         "test flood",

                         WA_DragBar,       TRUE,

                         WA_CloseGadget,   TRUE,

                         WA_NoCareRefresh, TRUE,

                         WA_SmartRefresh,  TRUE,

                         TAG_DONE);

    if(win)

    {

        WORD centreX, centreY;

        struct TmpRas tr;

        LONG size;

        UBYTE *buf;



        centreX = (win->Width + win->BorderLeft - win->BorderRight) / 2;

        centreY = (win->Height + win->BorderTop - win->BorderBottom) / 2;



        SetOutlinePen(win->RPort, 1);

        SetAPen(win->RPort, 1);

        SetDrPt(win->RPort, 0xFF);

        DrawCircle(win->RPort, centreX, centreY, 25);



        size = (200 * 200) / 8;



        buf = AllocVec(size, MEMF_CHIP);

        if(buf)

        {

            InitTmpRas(&tr, buf, size);

            win->RPort->TmpRas = &tr;



            Flood(win->RPort, 0, centreX, centreY);



            win->RPort->TmpRas = NULL;

            FreeVec(buf);

        }



        Wait(1 << win->UserPort->mp_SigBit);



        CloseWindow(win);

    }

    return 0;

}

Frickin Awesome!

That'll bring new-old-stock users back and perhaps some more who are curious!

Looking forward to the release.

Thanks Shadow. I have 10.6 and XCode 3.2(gcc 4.2), not Lion so hopefully I can still give it a try.

Have you actually tried the resulting programs on OS4 yet?

Strange.

I got it from the minimal 53.15 download but I can't remember when I downloaded it.

If it isn't in use in any serious way, it doesn't matter. I had just never herd of it and my curiosity was piqued.

It's at the bottom of graphics.doc in the autodocs, under the sub-category of pixie.

Pixie???

I see pixies mentioned in the graphics.library autodocs v53.15.

My question: What are Pixies (in the Amiga sense)? Are they sort of like sprites?

I think the crash is caused by not performing WaitIO() after AbortIO() so the program crashes on CloseDevice() due to the outstanding request.

@Mikey_C

Hey Mikey, like I said above, the front USB ports never worked for me either until I removed the sii drivers from Kickstart. Now it's fine. Must be a resource conflict.

@salass00

The front USB ports on my microA1 never worked until I removed the sii card drivers (I have no card and it is loaded in Kickstart). Now they work fine. This also seemed to fix an issue I was having with it refusing to reboot properly on <ctrl><amiga><amiga> (well, the PC-keyboard equivalent anyway).

@Mikey_C

I've got a microA1 and pretty much use it every day, but I wouldn't want to bother with a riser. It's more than 6 years old already and I'm looking forward to upgrading, hopefully to the X1000 if it is not insanely expensive to get one in Oz.
