Height in pixels
Optionalfile_Image file size in bytes. Required by agents that advertise a max_file_size_kb constraint.
Optionalpixel_Intrinsic pixels per logical render pixel (for example 2 for a 600×500 image intended to render at 300×250). Optional because a validator can infer the ratio when the target format declares logical dimensions. When supplied, it MUST agree with both width / logical_width and height / logical_height; it is never a substitute for the intrinsic width and height fields.
