XmippRaw

Xmipp RAW Format

No header information is in the file, only the pixel information row by row. An auxiliary file (usually with the same name as the data file plus extension inf) may be provided with file dimension and some extra information: the bits per sample and samples per pixel, max and minimum values and type (signed/unsigned) of sort is mapped to each point when appropriate.

Ainf file looks like

# Bits per sample
bitspersample= 8
# Samples per pixel
samplesperpixel= 1
# Image width
Xdim= 2000
# Image length
Ydim= 3000
# offset in bytes (Optional, zero by default)
offset= 0
# Is a signed or Unsigned int (Optional, by default true)
is_signed = true

NOTE: bitspersample= 32 is understood as float.
