For big endian CPUs, the byte order is ARGB. - enumerator SNPE\_IMAGE\_ENCODING\_RGBA = 3 - The RGBA format consists of 4 bytes per pixel: one byte for Red, one for Green, one for Blue, and one for the alpha channel. The alpha channel is ignored. The byte ordering is endian independent and is always in RGBA byte order. - enumerator SNPE\_IMAGE\_ENCODING\_GRAYSCALE = 4 - The GRAYSCALE format is for 8-bit grayscale. - enumerator SNPE\_IMAGE\_ENCODING\_NV21 = 5 - NV21 is the Android version of YUV. The Chrominance is down sampled and has a subsampling ratio of 4:2:0. Note that this image format has 3 channels, but the U and V channels are subsampled. For every four Y pixels there is one U and one V pixel. - enumerator SNPE\_IMAGE\_ENCODING\_BGR = 6 - The BGR format consists of 3 bytes per pixel: one byte for Red, one for Green and one for Blue. The byte ordering is endian independent and is always BGR byte order. - enum Snpe\_LogLevel\_t - Enumeration that lists the supported LogLevels that can be set by users. *Values:* - enumerator SNPE\_LOG\_LEVEL\_FATAL = 0 - Enumeration variable to be used by user to set logging level to FATAL. - enumerator SNPE\_LOG\_LEVEL\_ERROR = 1 - Enumeration variable to be used by user to set logging level to ERROR. - enumerator SNPE\_LOG\_LEVEL\_WARN = 2 - Enumeration variable to be used by user to set logging level to WARN. - enumerator SNPE\_LOG\_LEVEL\_INFO = 3 - Enumeration variable to be used by user to set logging level to INFO. - enumerator SNPE\_LOG\_LEVEL\_VERBOSE = 4 - Enumeration variable to be used by user to set logging level to VERBOSE. - enum Snpe\_IOBufferDataType\_t - Enumeration that list the supported data types for buffers *Values:* - enumerator SNPE\_IO\_BUFFER\_DATATYPE\_UNSPECIFIED = 0 - Unspecified. - enumerator SNPE\_IO\_BUFFER\_DATATYPE\_FLOATING\_POINT\_32 = 1 - 32-bit floating point - enumerator SNPE\_IO\_BUFFER\_DATATYPE\_FLOATING\_POINT\_16 = 2 - 16-bit floating point - enumerator SNPE\_IO\_BUFFER\_DATATYPE\_FIXED\_POINT\_8 = 3 - 8-bit fixed point - enumerator SNPE\_IO\_BUFFER\_DATATYPE\_FIXED\_POINT\_16 = 4 - 16-bit fixed point - enum Snpe\_CacheCompatibility\_t - Enumeration that list the mode of checking compatibility *Values:* - enumerator SNPE\_CACHE\_COMPATIBILITY\_PERMISSIVE = 0 - A binary cache is compatible if it could run on the device. This is the default. - enumerator SNPE\_CACHE\_COMPATIBILITY\_STRICT = 1 - A binary cache is compatible if it could run on the device and fully utilize hardware capability. - enumerator SNPE\_CACHE\_COMPATIBILITY\_ALWAYS\_GENERATE\_NEW\_CACHE = 2 - A binary cache is always incompatible. SNPE will generate new cache. Last Published: Jun 04, 2026
