	)

Attempt to read the next keyword, returning the string value if it is a continuation of the previous string keyword value. This uses the HEASARC convention for continuing long string values over multiple keywords. Each continued string is terminated with a backslash character, and the continuation follows on the next keyword which must have the name CONTINUE without an equal sign in column 9 of the card. If the next card is not a continuation, then the returned value string will be null.

Parameters

[in]	fptr	FITS file pointer
[out]	value	continued string value
[out]	comm	continued comment string
[in,out]	status	error status

	)

Parse the image compression specification that was give in square brackets following the output FITS file name, as in these examples:

myfile.fits[compress] - default Rice compression, row by row myfile.fits[compress TYPE] - the first letter of TYPE defines the compression algorithm: R = Rice G = GZIP H = HCOMPRESS HS = HCOMPRESS (with smoothing) B - BZIP2 P = PLIO

myfile.fits[compress TYPE 100,100] - the numbers give the dimensions of the compression tiles. Default is NAXIS1, 1, 1, ...

other optional parameters may be specified following a semi-colon

myfile.fits[compress; q 8.0] q specifies the floating point mufile.fits[compress TYPE; q -.0002] quantization level; myfile.fits[compress TYPE 100,100; q 10, s 25] s specifies the HCOMPRESS integer scaling parameter

The compression parameters are saved in the fptr->Fptr structure for use when writing FITS images.

convert an input string to a quoted string. Leading spaces are significant. FITS string keyword values must be at least 8 chars long so pad out string with spaces if necessary. Example: km/s ==> 'km/s ' Single quote characters in the input string will be replace by two single quote characters. e.g., o'brian ==> 'o''brian'

Parameters

[in]	instr	null terminated input string
[in,out]	outstr	null terminated quoted output string
[in,out]	status	error status

		int *	status
	)

Check if the file to be opened is already open. If so, then attach to it.

the input strings must not exceed the standard lengths of FLEN_FILENAME, MAX_PREFIX_LEN, etc.

   this function was changed so that for files of access method FILE://
   the file paths are compared using standard URL syntax and absolute
   paths (as opposed to relative paths). This eliminates some instances
   where a file is already opened but it is not realized because it
   was opened with another file path. For instance, if the CWD is
   /a/b/c and I open /a/b/c/foo.fits then open ./foo.fits the previous
   version of this function would not have reconized that the two files
   were the same. This version does recognize that the two files are
   the same.

Parameters

[in,out]	fptr	FITS file pointer
[in]	mode	0 = open readonly; 1 = read/write
[out]	isopen	1 = file is already open
[in,out]	status	error status

Read a consecutive set of pixels from a compressed image. This routine interpretes the n-dimensional image as a long one-dimensional array. This is actually a rather inconvenient way to read compressed images in general, and could be rather inefficient if the requested pixels to be read are located in many different image compression tiles.

The general strategy used here is to read the requested pixels in blocks that correspond to rectangular image sections.

Here is the caller graph for this function:

int fits_translate_pixkeyword	(	char *	inrec,
		char *	outrec,
		char *	patterns[][2],
		int	npat,
		int	naxis,
		int *	colnum,
		int *	pat_num,
		int *	i,
		int *	j,
		int *	n,
		int *	m,
		int *	l,
		int *	status
	)

Translate a keyword name to a new name, based on a set of patterns. The user passes an array of patterns to be matched. Input pattern number i is pattern[i][0], and output pattern number i is pattern[i][1]. Keywords are matched against the input patterns. If a match is found then the keyword is re-written according to the output pattern.

Order is important. The first match is accepted. The fastest match will be made when templates with the same first character are grouped together.

Several characters have special meanings:

 i,j - single digits, preserved in output template
 n, m - column number of one or more digits, preserved in output template
 k - generic number of one or more digits, preserved in output template
 a - coordinate designator, preserved in output template
 # - number of one or more digits
 ? - any character
   - only allowed in first character position, to match all
     keywords; only useful as last pattern in the list

i, j, n, and m are returned by the routine.

For example, the input pattern "iCTYPn" will match "1CTYP5" (if n_value is 5); the output pattern "CTYPEi" will be re-written as "CTYPE1". Notice that "i" is preserved.

The following output patterns are special

Special output pattern characters:

"-" - do not copy a keyword that matches the corresponding input pattern

"+" - copy the input unchanged

The inrec string could be just the 8-char keyword name, or the entire 80-char header record. Characters 9 = 80 in the input string simply get appended to the translated keyword name.

If n_range = 0, then only keywords with 'n' equal to n_value will be considered as a pattern match. If n_range = +1, then all values of 'n' greater than or equal to n_value will be a match, and if -1, then values of 'n' less than or equal to n_value will match.

Parameters

[in]	inrec	input string
[out]	outrec	output converted string, or a null string if input does not match any of the patterns
[in]	patterns	pointer to input / output string
[in]	npat	number of templates passed
[in]	naxis	number of columns to be binned
[in]	colnum	numbers of the columns to be binned
[out]	pat_num	matched pattern number (0 based) or
[out]	i
[out]	j
[out]	n
[out]	m
[out]	l
[in,out]	status	error status

int imcomp_calc_max_elem	(	int	comptype,

Here is the caller graph for this function:

int imcomp_compress_image	(	fitsfile *	infptr,
		fitsfile *	outfptr,
		int *	status
	)

This routine does the following:

reads an image one tile at a time
if it is a float or double image, then it tries to quantize the pixels into scaled integers.
it then compressess the integer pixels, or if the it was not possible to quantize the floating point pixels, then it losslessly compresses them with gzip

writes the compressed byte stream to the output FITS file

		void *	tiledata,
		long	tilelen,
		long	tilenx,
		long	tileny,
		int	nullcheck,
		void *	nullflagval,
		int *	status
	)

This is the main compression routine.

This routine does the following to the input tile of pixels:

if it is a float or double image, then it quantizes the pixels
compresses the integer pixel values
writes the compressed byte stream to the FITS file.

If the tile cannot be quantized than the raw float or double values are losslessly compressed with gzip and then written to the output table.

This input array may be modified by this routine. If the array is of type TINT or TFLOAT, and the compression type is HCOMPRESS, then it must have been allocated to be twice as large (8 bytes per pixel) to provide scratch space.

Note that this routine does not fully support the implicit datatype conversion that is supported when writing to normal FITS images. The datatype of the input array must have the same datatype (either signed or unsigned) as the output (compressed) FITS image in some cases.

Parameters

row	tile number = row in the binary table that holds the compressed data
