FloodFill and ExtFloodFill

[zedd151]

I have been working on using gdi32 drawing functions to use instead of bitmaps for my tic tac toe game.
I now have all of the bimaps removed from the game. All of the drawing issues have been resolved.


No Title bar, no movable borders. You close the program with the ESC key.    Plain and simple.
I might add an ini file, for the user to select their own color for X and O. This image shows another variation of contrasting colors for X and O.

Can't you just draw a line using a wide pen? For the X.

I have not.    I was spending way too much time trying to figure the FloodFill problems out.
What would the 'points' of the X look like, I hope not rounded.
I'll try that when I get back inside, to see how it looks.

Think of a thick texta (sharpie?)

Okay. If needed I could always put in a coupla lines to make the points less round and more square like the bitmap.
I'll post my progress in a little while. 

It never dawned on me to try it. I did think about using extra large fonts though.
Speaking of fonts, I used to have a bootleg copy of Font Creator. You could design your own fonts, even from a bitmap.    I might just explore that possibility, if this doesn't look very good using wide pen..

Dunno if it'll help, but I have my own flood-fill routine I could post that you could try. Works for me.

First thing I thought of

Flashbacks to drawing on a 320x200x256 VGA screen on a 386sx. Everything.
None of this fancy Windows drawing stuff.

It needs a little tweaking, but I can live with that.

Thanks, sinsi. That works much better, it will look even better after a few adjustments.

I never had to suffer such Phun.

The new X looks friendlier

I totally missed your post earlier. Sorry.
Sure, you only need to post the essential bits. I won't need a full blown example. At least I don't think I will.

Why do you fear the old style? 
I still need to tweak it so it looks 'right' next to the O's.

I just had another overnight epiphany while I slept, sinsi. 

Why the hell don't I now use the thick pen to also draw the "O", so it will look much better when side by side with the new and improved "X".

Last night, I was thinking about making the X (created with a thick pen), look better and match it to the O, which was created using filled ellipses.

Kinda like making an apple look like an orange. 

Amazing what a little sleep can do, to restore common sense, or at least better thought processes.

I am using code that changes font to bigger size in my unicode chess,so big 'X' and 'O' could be used

I have considered that possibilty as well. I am currently working on a different approach, though.

YaY! I got 'er done.Thanks again sinsi for a simple solution. I like simplicity. But I still wonder why I had issues with FloodFill and ExtFloodFill.

Code Select Expand

    DrawX proc hDC:dword, color:dword, x:dword, y:dword
    local hPen:dword, hPenOld:dword
        invoke CreatePen, PS_SOLID, 20, red
        mov hPen, eax
        invoke SelectObject, hDC, hPen
        mov hPenOld, eax
        mov ecx, x
        mov edx, y
        add ecx, 26
        add edx, 26
        invoke MoveToEx, hDC, ecx, edx, 0
        mov ecx, x
        add ecx, 112
        mov edx, y
        add edx, 112
        invoke LineTo, hDC, ecx, edx
        mov ecx, x
        add ecx, 112
        mov edx, y
        add edx, 26
        invoke MoveToEx, hDC, ecx, edx, 0
        mov ecx, x
        mov edx, y
        add ecx, 26
        add edx, 112
        invoke LineTo, hDC, ecx, edx
        invoke SelectObject, hDC, hPenOld
        invoke DeleteObject, hPen
        ret
    DrawX endp

    DrawO proc hDC:dword, hback:dword, hfill:dword, x:dword, y:dword
    local hPen:dword
        invoke SelectObject, hDC, hback
        invoke CreatePen, PS_SOLID, 18, blue
        mov hPen, eax
        invoke SelectObject, hDC, hPen
        add x, 32
        mov eax, x
        add eax, 96
        add y, 32
        mov ecx, y
        add ecx, 96
        invoke Ellipse, hDC, x, y, eax, ecx
        ret
    DrawO endp

So that issue is still unresolved. I must have spent the better part of half a day messing around trying to get either of those to behave.

Have you ever considered using the CreatePolygonRgn and FillRgn functions with two regions, one for each the oblique parts of the X.

It would fill the center part of the X twice but who cares!
