.SH DESCRIPTION
|
|
|
|
|
im_fexists(3) returns non-zero if the named file exists and is readable. Args
|
|
|
|
|
as printf(3).
|
|
|
|
|
|
|
|
|
|
im_isvips(3) tests a file for vips-ness.
|
|
|
|
|
|
|
|
|
|
im_isMSBfirst(3) returns true (1) if the file is in most-significant-byte first
|
|
|
|
|
form. This is the byte order used on the SPARC architecture, and others. It
|
|
|
|
|
returns false (0)for intel-order images.
|
|
|
|
|
|
|
|
|
|
im_amiMSBfirst(3) returns true (1) if this processor is MSB first.
|
|
|
|
|
|
|
|
|
|
im_isfile(3) returns true if the descriptor corresponds to some disc object,
|
|
|
|
|
that is, was opened with modes "r", "rw" or "w".
|
|
|
|
|
|
|
|
|
|
im_ispartial(3) returns true if the descriptor is partial,
|
|
|
|
|
that is, was opened with mode "p".
|
|
|
|
|
|
|
|
|
|
The rest of these functions test im\-\>BandFmt, returning logical truth
|
|
|
|
|
(non-zero) if BandFmt is one of a number of possibles, and returning zero if
|
|
|
|
|
it is not.
|
|
|
|
|
|
|
|
|
|
im_isint(3) (is integer type) returns true if im\-\>BandFmt is one of FMTUCHAR,
|
|
|
|
|
FMTCHAR, FMTUSHORT, FMTSHORT, FMTUINT or FMTINT.
|
|
|
|
|
|
|
|
|
|
im_isuint(3) (is unsigned integer type) returns true if im\-\>BandFmt is one of
|
|
|
|
|
FMTUCHAR, FMTUSHORT or FMTUINT.
|
|
|
|
|
|
|
|
|
|
im_isfloat(3) (is floating point type) returns true if im\-\>BandFmt is one of
|
|
|
|
|
FMTFLOAT or FMTDOUBLE.
|
|
|
|
|
|
|
|
|
|
im_isscalar(3) (is scalar type) returns true if im\-\>BandFmt is one of FMTUCHAR,
|
|
|
|
|
FMTCHAR, FMTUSHORT, FMTSHORT, FMTUINT, FMTINT, FMTFLOAT or FMTDOUBLE.
|
|
|
|
|
|
|
|
|
|
im_iscomplex(3) (is complex type) returns true if im\-\>BandFmt is one of
|
|
|
|
|
FMTCOMPLEX or FMTDPCOMPLEX.
