annotate m4/ax_blas.m4 @ 17367:cf5d41cc3695
Expand imfinfo to read Exif tags and GPS information.
* __magick_read__.cc (is_valid_exif, fill_exif, fill_exif_ints,
fill_exif_floats): New functions to parse the strings returned
from GraphicsMagick's attribute() and get actual value in the
Exif tag.
(__magick_finfo): implement reading of Exif tags. New fields
in the base struct being returned: Software, Make, Model,
DateTime, ImageDescription, Artist, Copyright, DigitalCamera,
and GPSInfo. The last two are structs in their own that contain
the rest of values from Exif (a rather long list of possible
values). Move obtaining DisposalMethod outside of the main loop
since it is only done for GIF files.
* imfinfo.m: document new fields on output.

| 5 # SYNOPSIS | |
| 6 # | |
| 7 # AX_BLAS([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]]) | |
| 8 # | |
| 9 # DESCRIPTION | |
| 10 # | |
| 11 # This macro looks for a library that implements the BLAS linear-algebra | |
| 12 # interface (see http://www.netlib.org/blas/). On success, it sets the | |
| 13 # BLAS_LIBS output variable to hold the requisite library linkages. | |
| 14 # | |
| 15 # To link with BLAS, you should link with: | |
| 16 # | |
| 17 # $BLAS_LIBS $LIBS $FLIBS | |
| 18 # | |
| 19 # in that order. FLIBS is the output variable of the | |
| 20 # AC_F77_LIBRARY_LDFLAGS macro (called if necessary by AX_BLAS), and is | |
| 21 # sometimes necessary in order to link with F77 libraries. Users will also | |
| 22 # need to use AC_F77_DUMMY_MAIN (see the autoconf manual), for the same | |
| 23 # reason. | |
| 24 # | |
| 25 # Many libraries are searched for, from ATLAS to CXML to ESSL. The user | |
| 26 # may also use --with-blas=<lib> in order to use some specific BLAS | |
| 27 # library <lib>. In order to link successfully, however, be aware that you | |
| 28 # will probably need to use the same Fortran compiler (which can be set | |
| 29 # via the F77 env. var.) as was used to compile the BLAS library. | |
| 30 # | |
| 31 # ACTION-IF-FOUND is a list of shell commands to run if a BLAS library is | |
| 32 # found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it is | |
| 33 # not found. If ACTION-IF-FOUND is not specified, the default action will | |
| 34 # define HAVE_BLAS. | |
