function ImageSplitter¶

ImageSplitter() =default

function ImageSplitter¶

ImageSplitter(
    const char * filename,
    uint64_t blockstride,
    uint64_t blocklinestride,
    uint64_t blocklen,
    int channels
)

Parameters:

filename - path/to/file.ext
blockstride - Stride to use for access pattern
blocklinestride - Line stride in bytes to get to next block start
blocklen - Block Length in bytes

Split an image loaded from file

function ImageSplitter¶

ImageSplitter(
    const std::vector< char > & buffer,
    uint64_t blockstride,
    uint64_t blocklinestride,

    int channels
)

Parameters:

buffer - Raw data of image file
blockstride - Stride to use for access pattern
blocklinestride - Line stride in bytes to get to next block start
blocklen - Block Length in bytes

Split an image loaded from raw data of a file loaded elsewhere, i.e. asynciomanager
