Declaration [src]
GeglBufferIterator*
gegl_buffer_iterator_new (
GeglBuffer* buffer,
const GeglRectangle* roi,
gint level,
const Babl* format,
GeglAccessMode access_mode,
GeglAbyssPolicy abyss_policy,
gint max_slots
)
Description [src]
Create a new buffer iterator, this buffer will be iterated through in linear chunks, some chunks might be full tiles the coordinates, see the documentation of gegl_buffer_iterator_next for how to use it and destroy it.
This method is not directly available to language bindings.
Parameters
roi-
Type:
GeglRectangleThe rectangle to iterate over.
The data is owned by the caller of the function. level-
Type:
gintThe level at which we are iterating, the roi will indicate the extent at 1:1, x,y,width and height are/(2^level)
format-
Type:
BablThe format we want to process this buffers data in, pass 0 to use the buffers format.
The data is owned by the caller of the function. access_mode-
Type:
GeglAccessModeWhether we need reading or writing to this buffer one of GEGL_BUFFER_READ, GEGL_BUFFER_WRITE and GEGL_BUFFER_READWRITE.
abyss_policy-
Type:
GeglAbyssPolicyHow request outside the buffer extent are handled.
max_slots-
Type:
gintNo description available.
Return value
Type: GeglBufferIterator
A new buffer iterator that can be used to iterate through the buffers pixels.
| The data is owned by the instance. |
