return a texture image

Signature

glGetTexImage( GLenum ( target ) , GLint ( level ) , GLenum ( format ) , GLenum ( type ) , GLvoid * ( img ) )-> void

glGetTexImage( target , level , format , type , array = None , outputType = <type 'str'> )

Get a texture-level as an image
 target -- enum constant for the texture engine to be read
 level -- the mip-map level to read
 format -- image format to read out the data
 type -- data-type into which to read the data
 array -- optional array/offset into which to store the value
 outputType -- default (bytes) provides string output of the
 results iff OpenGL.UNSIGNED_BYTE_IMAGES_AS_STRING is True
 and type == GL_UNSIGNED_BYTE. Any other value will cause
 output in the default array output format.
 returns the pixel data array in the format defined by the
 format, type and outputType
