                   ColorBufferImage

A color framebuffer.

This class is used to wrap both the primary color buffer (i.e., the back buffer) or any one of the auxilliary buffers.

Method Details

get_texture

get_texture(self, rectangle=False)

A Texture view of this image.

By default, textures are created with dimensions that are powers of two. Smaller images will return a TextureRegion that covers just the image portion of the larger texture. This restriction is required on older video cards, and for compressed textures, or where texture repeat modes will be used, or where mipmapping is desired.

If the rectangle parameter is True, this restriction is ignored and a texture the size of the image may be created if the driver supports the GL_ARB_texture_rectangle or GL_NV_texture_rectangle extensions. If the extensions are not present or the image already is a texture, the rectangle parameter is ignored.

Examine Texture.target to determine if the returned texture is a rectangle (GL_TEXTURE_RECTANGLE_ARB or GL_TEXTURE_RECTANGLE_NV) or not (GL_TEXTURE_2D).

Changes to the returned instance may or may not be reflected in this image.

Returns: Texture

AbstractImage.get_texture

blit_to_texture

blit_to_texture(self, target, level, x, y, z)

Draw this image on the currently bound texture at target.

This image is copied into the texture such that this image's anchor point is aligned with the given x and y coordinates of the destination texture. If the currently bound texture is a 3D texture, the z coordinate gives the image slice to blit into.

AbstractImage.blit_to_texture
