Method Summary

static void	depureTexture(Texture texture, float limit) removes mistakes which are present on some ruined gif or png . or problems you may have during the application of the blender-effect on images with transparents parts.
static int	getNextPowerOfTwo(int fold) get the closest greater power of 2 to the fold number
static int	getNextPowerOfTwoHW(int fold) get the closest greater power of 2 to the fold number This version check if the current computer's hardware support Not Power Of 2 texture: in this case this method will retourn the fold istead of the closest greater power of 2 value.

Method Detail

depureTexture

public static void depureTexture(Texture texture,
                                 float limit)

removes mistakes which are present on some ruined gif or png .
or problems you may have during the application of the blender-effect on images with transparents parts.

Parameters:

texture - source texture

limit - a value [in range of 0:1] that indicates the depure

getNextPowerOfTwo

public static int getNextPowerOfTwo(int fold)

get the closest greater power of 2 to the fold number

Parameters:

fold - The target number

Returns:

The power of 2

getNextPowerOfTwoHW

public static int getNextPowerOfTwoHW(int fold)

get the closest greater power of 2 to the fold number
This version check if the current computer's hardware support Not Power Of 2 texture: in this case this method will retourn the fold istead of the closest greater power of 2 value.

Parameters:

fold - The target number

Returns:

The power of 2
