Expand description

Creates GPU-backed Image from the provided GPU texture associated with context. GPU texture must stay valid and unchanged until texture_release_proc is called by Skia. Skia will call texture_release_proc with the passed-in release_context when Image is deleted or no longer refers to the texture. A non-null Image is returned if format of backend_texture is recognized and supported. Recognized formats vary by GPU backend. Note: When using a DDL recording context, texture_release_proc will be called on the GPU thread after the DDL is played back on the direct context.

  • context - GPU context
  • backend_texture - texture residing on GPU
  • color_space - This describes the color space of this image’s contents, as seen after sampling. In general, if the format of the backend texture is SRGB, some linear color_space should be supplied (e.g., ColorSpace::new_srgb_linear()). If the format of the backend texture is linear, then the color_space should include a description of the transfer function as well (e.g., ColorSpace::new_srgb()).
  • texture_release_proc - function called when texture can be released
  • release_context - state passed to texture_release_proc

Returns: created Image, or None
