Expand description

Wraps a GPU-backed texture into Surface. Caller must ensure the texture is valid for the lifetime of returned Surface. If sample_cnt greater than zero, creates an intermediate MSAA Surface which is used for drawing backend_texture.

Surface is returned if all parameters are valid. backend_texture is valid if its pixel configuration agrees with color_space and context; for instance, if backend_texture has an sRGB configuration, then context must support sRGB, and color_space must be present. Further, backend_texture width and height must not exceed context capabilities, and the context must be able to support back-end textures.

  • context - GPU context
  • backend_texture - texture residing on GPU
  • sample_cnt - samples per pixel, or 0 to disable full scene anti-aliasing
  • color_space - range of colors; may be None
  • surface_props - LCD striping orientation and setting for device independent fonts; may be None Returns: Surface if all parameters are valid; otherwise, None
