class MMTexture(Texture) |

Mip-mapped texture object
Note: You'll want your images to use
minFilter = GL_LINEAR_MIPMAP_NEAREST
to actually see any effect from using a
MMTexture.

- Method resolution order:
- MMTexture
- Texture
- object
Methods defined here:
- ensurePow2(self, image)
- Ensure that the PIL image is pow2 x pow2 dimensions
Mip-mapping does this already if I'm not mistaken, so
we just return image unchanged.
- store(self, components, format, x, y, image)
- define the texture's parameters...
components -- number of components (3 or 4 for
RGB and RGBA respectively)
format -- GL_RGB, GL_RGBA, GL_LUMINANCE
x,y -- dimensions of the image
image -- string, data in raw (unencoded) format
Data and non-method functions defined here:
- __doc__ = "Mip-mapped texture object\n\n\tNote: You'll want yo...ctually see any effect from using a\n\tMMTexture.\n\t"
- __module__ = 'OpenGLContext.texture'
Methods inherited from Texture:
- __call__(self)
- Enable and select the texture...
See:
glBindTexture, glEnable(GL_TEXTURE_2D)
- __del__(self, glDeleteTextures=<built-in function glDeleteTextures>)
- Clean up the OpenGL display-list resources
See:
glDeleteTextures
- __init__(self, image=None)
- Initialise the texture, if image is not None, store it
image -- optional PIL image to store
- ensureRGB(self, image)
- Ensure that the PIL image is in RGB mode
Note:
This method will create a _new_ PIL image if
the image is in Paletted mode, otherwise just
returns the same image object.
- fromPIL(self, image)
- Automated storage of image data from a PIL Image instance
Uses the ensureRGB method to convert the image to RGB,
then ensurePow2 to make the image a valid size for OpenGL,
then calls store(...) with the appropriate arguments.
Returns the number of components in the image
Data and non-method functions inherited from Texture:
- __dict__ = <dict-proxy object at 0x07156738>
- __weakref__ = <member '__weakref__' of 'Texture' objects>
Methods inherited from object:
- __delattr__(...)
- x.__delattr__('name') <==> del x.name
- __getattribute__(...)
- x.__getattribute__('name') <==> x.name
- __hash__(...)
- x.__hash__() <==> hash(x)
- __reduce__(...)
- helper for pickle
- __repr__(...)
- x.__repr__() <==> repr(x)
- __setattr__(...)
- x.__setattr__('name', value) <==> x.name = value
- __str__(...)
- x.__str__() <==> str(x)
Data and non-method functions inherited from object:
- __class__ = <type 'type'>
- __new__ = <built-in method __new__ of type object at 0x1E0BD978>
- T.__new__(S, ...) -> a new object with type S, a subtype of T

class Texture(object) |
| |
Holder for an OpenGL compiled texture
This object holds onto a texture until it
is deleted. Provides methods for storing
raw data or PIL images (store and fromPIL
respectively)
Attributes:
components -- number of components in the image,
if 0, then there is no currently stored image
texture -- OpenGL textureID as returned by a call
to glGenTextures(1), will be freed when the
Texture object is deleted

This method will create a _new_ PIL image if
the image is not a valid size (It will use BICUBIC
filtering (from PIL) to do the resizing). Otherwise
just returns the same image object.
