How to fix letterbox sprite glitch

Yan

I have a problem with my sprites. Ive got next code in main

local sprite = Bitmap.new(Texture.new("textures/playertexture.png"))
stage:addChild(sprite)

And my project settings is Letterbox 540*960

If I use 540*960 Ive got good smooth view like this dl.dropboxusercontent.com/u/51701372/good.JPG

when I change Player resolution to 768*1024 and any other NOT proportional Ive got glitchy image like this dl.dropboxusercontent.com/u/51701372/shit.JPG

Why all scalemodes make sprites looks glitchy, when I didnt use any scale direct on sprite ? How to fix it ?

Try to set antialising true, i guess it will solve your problem. It is the second optional parameter of Bitmap.new function, by default it is false i guess.
local sprite = Bitmap.new(Texture.new("textures/playertexture.png"),true)
stage:addChild(sprite)


Edit: The parameter should be passed to Texture not to Bitmap function

Yan

Heres Images, some glitchy places marked

Tried just now .. didnt helps =(

Sorry my bad the parameter should be passed to Texture not to bitmap.

local sprite = Bitmap.new(Texture.new("textures/playertexture.png",true)) stage:addChild(sprite)

Yan

Yes, ive just googled "gideros anti alising", and found this tree giderosmobile.com/forum/discussion/484/anti-aliasing/p1

Marked ur answer as Accepted, YOU saved a f*** LOT time for me, THANK A LOT!

talis

You re welcome.

One more question and what to do if I using next thing

local tr = Bitmap.new(texturePack:getTextureRegion(regions[i]))

Yan

Sorry, found !

texturePacker = TexturePack.new("spritesheet.txt", "spritesheets/spritesheet.png",true)
local texture = texturePacker:getTextureRegion( texture_path)

But WHY this is NOT IN DOCUMENTATION ??? I can read manuals, im not a child, how to find this all, and where, if not in manuals ?

Thanks, theres something about filtering and nothing about what filters do I ca use, and how to enable anti-aliasing =(

well, filtering is a synonym of anti-aliasing in this context.
assuming this, it's emphasised well i think, there are even examples:

@Yan OT: I saw your texturepack in the post above, you can save some texture memory by flipping the sprites in lua instead of providing 2 images (of which 1 flipped): try using Sprite:setScaleX(-1)

Yan

well i thought that this function will take more processor time, isnt it ?

unfortunately, Im maybe stpd, but I didnt see any list of available options, that I can passs to this contructor =(

@Yan I suppose so, but from my experience it's nothing compared to the benefits of loading half of the textures
