Gegl – 0.4

An opaque type representing a metadata iterator.

Struct to describe how a metadata variable is mapped from the name used by the image file module to the name used by Gegl. An optional transform function may be specified, e.g. to transform from a GDatetime to a string.

Flags controlling the mapping strategy.

An enumerated type specifying resolution (density) units. If resolution units are unknown, X and Y resolution specify the pixel aspect ratio.

Specifies the type of function passed to gegl_parallel_distribute_area().

Specifies the type of function passed to gegl_parallel_distribute().

Specifies the type of function passed to gegl_parallel_distribute_range().

Apply the operation to buffer, overwritting the contents of buffer.

Apply the operation to buffer, overwritting the contents of buffer.

Allocated 0’d memory.

Disable OpenCL.

Initialize and enable OpenCL, calling this function again will re-enable OpenCL if it has been disabled.

Check if OpenCL is enabled.

Returns a GeglConfig object with properties that can be manipulated to control GEGLs behavior.

Create a node chain from an unparsed commandline string.

Create a node chain from argv style list of op data.

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.

Apply the operation to source_buffer, returning the result in a new buffer.

Apply the operation to source_buffer, returning the result in a new buffer.

Returns a value sutable to pass to the GeglBuffer constructor or any other property that expects a Babl format.

Frees the memory pointed to by mem. If mem is NULL, does nothing.

Returns a GOptionGroup for the commandline arguments recognized by GEGL. You should add this group to your GOptionContext with g_option_context_add_group() if you are using g_option_context_parse() to parse your commandline arguments.

This function fetches the version of the GEGL library being used by the running process.

Dump the bounds and format of each node in the graph to stdout.

Dump the region that will be rendered for each node to fulfill the request.

Call this function before using any other GEGL functions. It will initialize everything needed to operate GEGL and parses some standard command line options. argc and argv are adjusted accordingly so your own code will never see those standard arguments.

Load all gegl modules found in the given directory.

Allocates n_bytes of memory. If n_bytes is 0, returns NULL.

Checks if all the bytes of the memory block ptr, of size size, are equal to zero.

Fill dst_ptr with count copies of the bytes in src_ptr.

Distributes the execution of a function across multiple threads, by calling it with a different index on each thread.

Distributes the processing of a planar data-structure across multiple threads, by calling the given function with different sub-areas on different threads.

Distributes the processing of a linear data-structure across multiple threads, by calling the given function with different sub-ranges on different threads.

Creates a new GParamSpec instance specifying a GeglAudioFragment property.

Creates a new GParamSpec instance specifying a GeglColor property.

Creates a new GParamSpec instance specifying a GeglColor property.

Get the default color value of the param spec.

Creates a new GParamSpec instance specifying a GeglCurve property.

Creates a new GeglParamSpecDouble instance.

Creates a new GeglParamSpecEnum instance.

Creates a new GeglParamSpecFilePath instance.

Creates a new GeglParamSpecFormat instance specifying a Babl format.

Creates a new GeglParamSpecInt instance.

Creates a new GParamSpec instance specifying a GeglPath property.

Creates a new GeglParamSpecSeed instance specifying an integer random seed.

Creates a new GeglParamSpecString instance.

Creates a new GeglParamSpecUri instance.

Apply the operation to source_buffer, writing the results to target_buffer.

Apply the operation to source_buffer, writing the results to target_buffer.

Resets the cumulative data gathered by the GeglStats object returned by #gegl_stats().

Allocates size bytes of scratch memory.

Allocates size bytes of scratch memory, initialized to zero.

Frees the memory pointed to by ptr.

Returns a GeglStats object with properties that can be read to monitor GEGL statistics.

Allocates n_bytes of memory. If allocation fails, or if n_bytes is 0, returns NULL.

Evaluates to the height of the buffer’s extent.

Returns the number of pixels of the extent of the buffer.

Evaluates to the width of the buffer’s extent.

Evaluates to the X coordinate of the upper left corner of the buffer’s extent.

Evaluates to the Y coordinate of the upper left corner of the buffer’s extent.

Allocates n elements of type type using scratch memory. The returned pointer is cast to a pointer to the given type. Care is taken to avoid overflow when calculating the size of the allocated block.

Allocates n elements of type type using scratch memory, initialized to 0. The returned pointer is cast to a pointer to the given type. Care is taken to avoid overflow when calculating the size of the allocated block.
