Gegl.LookupFunction(value, data)

Parameters:

• value (float)

• data (object or None)

Return type:

float

Gegl.NodeFunction(node, *user_data)

Parameters:

• node (Gegl.PathItem)

• user_data (object or None)

Gegl.ParallelDistributeAreaFunc(area, *user_data)

Parameters:

• area (Gegl.Rectangle) – the current sub-area

• user_data (object or None) – user data pointer

Specifies the type of function passed to Gegl.parallel_distribute_area().

The function should process the sub-area specified by area.

Gegl.ParallelDistributeFunc(i, n, *user_data)

Parameters:

• i (int) – the current thread index, in the range [0,`n`)

• n (int) – the number of threads execution is distributed across

• user_data (object or None) – user data pointer

Specifies the type of function passed to Gegl.parallel_distribute().

The function should process the i-th part of the data, out of n equal parts. n may be less-than or equal-to the max_n argument passed to Gegl.parallel_distribute().

Gegl.ParallelDistributeRangeFunc(offset, size, *user_data)

Parameters:

• offset (int) – the current data offset

• size (int) – the current data size

• user_data (object or None) – user data pointer

Specifies the type of function passed to Gegl.parallel_distribute_range().

The function should process size elements of the data, starting at offset.

Gegl.SamplerGetFun(self, x, y, scale, output, repeat_mode)

Parameters:

• self (Gegl.Sampler)

• x (float)

• y (float)

• scale (Gegl.BufferMatrix2)

• output (object or None)

• repeat_mode (Gegl.AbyssPolicy)

Gegl.TileCallback(tile, *user_data)

Parameters:

• tile (Gegl.Tile)

• user_data (object or None)

Gegl.TileSourceCommand(gegl_tile_source, command, x, y, z, data)

Parameters:

• gegl_tile_source (Gegl.TileSource)

• command (Gegl.TileCommand)

• x (int)

• y (int)

• z (int)

• data (object or None)

Return type:

object or None
