| D | VK_EXT_image_compression_control.adoc | 10 This document proposes adding support for fixed-rate, or 'lossy', image compression.
18 Fixed-rate compression formats have so far not been supported.
22 The fixed-rate compression algorithms are implementation-specific and not standardized.
30 To enable fixed-rate compression, two options were considered:
33 . Add new fixed-rate compressed formats
