VIPS function listUsing VIPS — List of VIPS functions and operators |
Function list
VIPS has a set of operators each of which computes some useful image processing operation. Each operator is implemented as aGObject class, for exampleVipsGamma. Classes are identified by their uniquenickname, in this casegamma. From the command-line, C++ and most language bindings, you use the nickname to call the operator. For example in C++:
vips::VImage fred = ...; vips::VImage jim = fred.gamma();
or Python:
fred = jim.gamma()
VIPS has a set of C wrapper functions for calling operators, in this casevips_gamma():
VipsImage *fred = ...; VipsImage *jim; if (vips_gamma(fred, &jim, NULL)) ...error;
Some operators have many C convenience functions.
This table lists all the VIPS operators with their C convenience functions and a short description. It's supposed to be useful for searching. See the API docs each function links to for more details.
