Static variables
staticinlineread onlyCOMPRESSED_RG11_EAC:Int = 37490
Two-channel (red and green) unsigned format compression.
staticinlineread onlyCOMPRESSED_RGB8_PUNCHTHROUGH_ALPHA1_ETC2:Int = 37494
Similar to RGB8_ETC, but with ability to punch through the alpha channel, which means to make it completely opaque or transparent.
staticinlineread onlyCOMPRESSED_RGBA8_ETC2_EAC:Int = 37496
Compresses RGBA8 data. The RGB part is encoded the same as RGB_ETC2, but the alpha part is encoded separately.
staticinlineread onlyCOMPRESSED_SIGNED_R11_EAC:Int = 37489
One-channel (red) signed format compression.
staticinlineread onlyCOMPRESSED_SIGNED_RG11_EAC:Int = 37491
Two-channel (red and green) signed format compression.
staticinlineread onlyCOMPRESSED_SRGB8_ALPHA8_ETC2_EAC:Int = 37497
Compresses sRGBA8 data. The sRGB part is encoded the same as SRGB_ETC2, but the alpha part is encoded separately.
staticinlineread onlyCOMPRESSED_SRGB8_PUNCHTHROUGH_ALPHA1_ETC2:Int = 37495
Similar to SRGB8_ETC, but with ability to punch through the alpha channel, which means to make it completely opaque or transparent.
