Method Detail

loadTexture

public static Texture loadTexture(java.lang.String file,
                                  int minFilter,
                                  int magFilter)

loadTexture loads a new texture defined by the parameter string. Filter parameters are used to define the filtering of the texture. If there is an error loading the file, null is returned.

Parameters:

file - the filename of the texture image.

minFilter - the filter for the near values.

magFilter - the filter for the far values.

Returns:

the loaded texture. If there is a problem loading the texture, null is returned.

minFilter - the filter for the near values.

magFilter - the filter for the far values.

flipped - If true, the images Y values are flipped.

Returns:

the loaded texture. If there is a problem loading the texture, null is returned.

                                  int minFilter,
                                  int magFilter)

loadTexture loads a new texture defined by the parameter url. Filter parameters are used to define the filtering of the texture. If there is an error loading the file, null is returned.

Parameters:

file - the url of the texture image.

minFilter - the filter for the near values.

magFilter - the filter for the far values.

Returns:

the loaded texture. If there is a problem loading the texture, null is returned.

                                  int minFilter,
                                  int magFilter,
                                  float anisoLevel,
                                  boolean flipped)

public static Texture loadTexture(java.net.URL file,
                                  int minFilter,
                                  int magFilter,

                                  float anisoLevel,
                                  boolean flipped)

loadTexture loads a new texture defined by the parameter url. Filter parameters are used to define the filtering of the texture. If there is an error loading the file, null is returned.

Parameters:

file - the url of the texture image.

minFilter - the filter for the near values.

magFilter - the filter for the far values.

imageType - the image type to use. if -1, the type is determined by jME. If S3TC/DXT1[A] is available we use that. if -2, the type is determined by jME without using S3TC, even if available. See com.jme.image.Image for possible types.

flipped - If true, the images Y values are flipped.

Returns:

the loaded texture. If there is a problem loading the texture, null is returned.
