Functions
| apply_op |
Apply the operation to buffer, overwritting the contents of buffer. |
| apply_op_valist |
Apply the operation to buffer, overwritting the contents of buffer. |
| babl_variant | |
| calloc |
Allocated 0’d memory. |
| cl_disable |
Disable OpenCL. |
| cl_init |
Initialize and enable OpenCL, calling this function again will re-enable OpenCL if it has been disabled. |
| cl_is_accelerated |
Check if OpenCL is enabled. |
| config |
Returns a GeglConfig object with properties that can be manipulated to control GEGLs behavior. |
| create_chain |
Create a node chain from an unparsed commandline string. |
| create_chain_argv |
Create a node chain from argv style list of op data. |
| exit |
Call this function when you’re done using GEGL. It will clean up caches and write/dump debug information if the correct debug flags are set. |
| filter_op |
Apply the operation to source_buffer, returning the result in a new buffer. |
| filter_op_valist |
Apply the operation to source_buffer, returning the result in a new buffer. |
| format |
Returns a value sutable to pass to the GeglBuffer constructor or any other property that expects a Babl format. |
| format_get_name | |
| free |
Frees the memory pointed to by |
| get_option_group |
Returns a GOptionGroup for the commandline arguments recognized
by GEGL. You should add this group to your GOptionContext with |
| get_version |
This function fetches the version of the GEGL library being used by the running process. |
| graph_dump_outputs |
Dump the bounds and format of each node in the graph to stdout. |
| graph_dump_request |
Dump the region that will be rendered for each node to fulfill the request. |
| has_operation | |
| init |
Call this function before using any other GEGL functions. It will
initialize everything needed to operate GEGL and parses some
standard command line options. |
