A4 Image File Formats
There are five file formats available for saving camera images with
Camware.
BMP
Windows Bitmap Format, b/w or color 8 bit format-images, which have
been saved in BMP format can be loaded later only as 8 bit images, i.e. part
of the original information (10bit, 12bit or 14bit) is lost.
TIFF
Tag Image File Format, version 6.0 and lower. There is a 16bit monochrome
and color image format.
FTS
Flexible Image Transport System, Version 3.1. There is a 16 bit image
format. The NASA/Science Office of Standards and Technology (NOST) has
defined this format. Some programs use the FIT extension for this format.
ASCII
16 bit format, some mathematical programs prefer ASCII data.
b16
The “b16” 16 bit format is similar to the bmp format. However, 16 bit pixel
values are used instead of 8 bit pixel values. The 16 bit pixel values
represent "unsigned integer values", where the camera (12 bit values) sets
the higher 4 bits to zero.
The file format consists either of a "Basic Header" (6 Long-parameter) or of
an "Extended Header" (32 Long-parameter), the latter of which is optionally
for additional information. There might follow a variable comment field
(ASCII code). Finally, there is the actual data set that is saved linearly (as in
the case of BMP files).
With the exception of the first value, all parameters are "Long Integers" (4
Byte). The first 6 parameters must always exist. The rest of the parameters,
as well as the comment field, are optional.
