Expand description

Returns Surface on GPU indicated by context. Allocates memory for pixels, based on the width, height, and crate::ColorType in ImageInfo. budgeted selects whether allocation for pixels is tracked by context. image_info describes the pixel format in crate::ColorType, and transparency in crate::AlphaType, and color matching in crate::ColorSpace.

sample_count requests the number of samples per pixel. Pass zero to disable multi-sample anti-aliasing. The request is rounded up to the next supported count, or rounded down if it is larger than the maximum supported count.

surface_origin pins either the top-left or the bottom-left corner to the origin.

should_create_with_mips hints that crate::Image returned by Surface::image_snapshot is mip map.

  • context - GPU context
  • image_info - width, height, crate::ColorType, crate::AlphaType, crate::ColorSpace; width, or height, or both, may be zero
  • sample_count - samples per pixel, or 0 to disable full scene anti-aliasing
  • surface_props - LCD striping orientation and setting for device independent fonts; may be None
  • should_create_with_mips - hint that Surface will host mip map images Returns: Surface if all parameters are valid; otherwise, None
