Bitmap smoothing

[MiltonW]

Would be nice to have an option to set pixelsnapping and smoothing:

    _bitmap = new Bitmap(_bitmapData, PixelSnapping.AUTO, true));

@MiltonW what about my latest push? does it work as you prefer?

[MiltonW]

I think so, but I seem to have a problem with Flash (and HTML5).

Linux/Neko target:

Flash:

Same code, no Flash conditionals.
This occurs when I have

     text_retro.size = 0.57;                                             

If I don't use that (or use a nice round integer) it looks just as good as the other targets.
But if I then try to use text_retro.scaleX = 0.57 I get:

Invalid field access : set_scaleX

So I can't use the DisplayObject scaling anymore, which I would guess would not distort the image.

[Beeblerox]

let me think about it

[Beeblerox]

@MiltonW sorry that i haven't worked on it earlier, but i think i've fixed this issue.
could you try updated code?

[MiltonW]

No change I think. When I use HTML5/Flash I have the following behaviour:

     text_retro.size = 0.57;

     text_retro.scaleX = 0.57; text_retro.scaleY = 0.57;

Since scaleX/Y seems to work it is not really a problem (for me anyway :) ). Can't reproduce the 'Invalid field access : set_scaleX' anymore.

PS. Does look a bit smoother now that I look at it, but I don't think it has to do with smoothing...

[Beeblerox]

strange. this is what i've got on flash target with latest code (with size set to 0.57):
smoothing off

smoothing on

[MiltonW]

Yeah, a bit smoother, but what does it look like without size, and then scale it with scaleX/Y?

[Beeblerox]

it looks the same

[Beeblerox]

ok, here is another one fix.
it looks like if you change Bitmap's bitmapData then smoothing isn't applying to it anymore. so we have to reapply smoothing

[MiltonW]

It all doesn't seem to make a difference. All the smoothing does is smooth the jagged edges. The edges aren't there if I don't use size. So then I can use scaleX/Y and it stays crisp.

Try going fullscreen or even bigger and try to keep it this clean, no edges at all:

Again, if I then comment scaling, and use size:

This is only on Flash/HTML5. Using size = 0.57 and scaling the entire stage by 3.

[Beeblerox]

oh, so you were scaling stage also. and i've tested without it.
I guess it will be impossible to achieve this by using size then

[MiltonW]

No, I'm not scaling the stage, that was just to make the difference more obvious.

Hi there ,@Beeblerox Now how to disable smoohting ?
I'm using this frok by @flowplay
https://github.com/flowplay/BitmapFont
angelCodeField.smoothing = false; // not working , it's always smoothing, I'm using pxiel font , so need to be non-smoothing
p.s. when set scale to 2 , it's smoothing with white blurry border
Thanks

Just find a way to fix :
Find this line
_tilemap = new Tilemap(tileMapWidth, tileMapHeight, font.tileset);
Add this.smoothing to the end
_tilemap = new Tilemap(tileMapWidth, tileMapHeight, font.tileset,this.smoothing);
