static

Load a texture from a file Loads a texture from a file, restricting in size if needed based on maxHeight and maxWidth. Note that these are the ideal size to load at - the returned texture may be smaller or larger than these.

Parameters

texturePath	the path of the texture to load.
idealWidth	the ideal width of the texture (defaults to 0, no ideal width).
idealHeight	the ideal height of the texture (defaults to 0, no ideal height).
strMimeType	mimetype of the given texture if available (defaults to empty)

Returns: a CBaseTexture pointer to the created texture - NULL if the texture failed to load.

static

Load a texture from a file in memory Loads a texture from a file in memory, restricting in size if needed based on maxHeight and maxWidth. Note that these are the ideal size to load at - the returned texture may be smaller or larger than these.

Parameters

bufferSize	the size of buffer.
mimeType	the mime type of the file in buffer.
idealWidth	the ideal width of the texture (defaults to 0, no ideal width).
idealHeight	the ideal height of the texture (defaults to 0, no ideal height).

Returns: a CBaseTexture pointer to the created texture - NULL if the texture failed to load.
