Optional ReadonlymaximumBound on the width × height × 4 RGBA8 size estimate; default 64 MiB. Native bitmap storage can differ and is not measurable through this seam. Positive infinity disables this estimate check.
Optional ReadonlymaximumMaximum RGBA8 size estimate divided by encoded bytes; default 1000. Positive infinity disables this estimate check.
Optional ReadonlymaximumRequire an enforced decoder linear-memory ceiling, in bytes. The decoder must come directly from a bounded factory with a ceiling no larger than this safe integer (64 KiB–4 GiB). Native callbacks are refused at construction. Omit for legacy platform decoding without a heap cap. Encoded input, returned RGBA bytes and row-flip copies are separate from the decoder heap; this is not a process-wide memory limit.
Optional ReadonlynameDiagnostics label used in error context.loader. Defaults to "texture".
Optional ReadonlyprobeOptional header reader; see TexelProbeLike and §96, above.
Optional ReadonlyrequireRequire a recognized dimension probe before decoding. Default false.
RGBA8 size estimates and an optional enforced decoder heap ceiling (§96).
