texture quality problem,cocos2dx runtime

wjwjw

zhangfei_spine.zipI use spine animation Cocos2d-x.

And found the texture quality is not good as the same file create by sprite.

I try to decrease the frames,remove the scale option ,use the RGBA8888 format
But got the same results

I also ask a same problem here but not one provide solution
http://forum.cocos.com/t/spine-cocos/41487

as the image show, It shows a spine object and a sprite create with same picture file.
Loading Image
it's left hand and body show differences

anyone tell me how can I get the spine with hight quality textures

Thank you

I don't really see a difference in your pic. It looks like one the character is larger than the pieces, which means it is being scaled up. Any time you rotate or scale an image and it no longer matches 1 to 1 with screen pixels, there must be some filtering and a loss of quality.

It is a filtering issue. When your image is scaled, neighboring pixels are blended together. Couple of options...

Double the resolution of source textures, scale down instead of up. This has the added benefit of looking great on Retina Devices.
Color correct the output

On the attached GIF, I've used very simple color correction on the gauntlet, shifting the blacks back into the black range. It's very subtle, but effective.
For the chest area, I shifted the blacks and did a little too much gamma correction. It's exaggerated to see the effect.

Also, because I saved as GIF, there is some banding. It looks better as PNG.

To do color correction, you just write a simple shader for rendering the spine asset.

You can also look into color grading, which will not only allow you to do color correction, but complete grading of the scene in a post processing pass. The color correction gets baked into the LookUpTable (LUT).

Mild Color Correction, PNG (no gif banding)

The slight blurriness can also come from mipmapping.
Not sure how that works in cocos2dx.
Try looking for code that mentions something like: GL_LINEAR_MIPMAP_LINEAR
