Method

GeglBuffercopy

Declaration [src]

void
gegl_buffer_copy (
  GeglBuffer* src,
  const GeglRectangle* src_rect,
  GeglAbyssPolicy repeat_mode,
  GeglBuffer* dst,
  const GeglRectangle* dst_rect
)

Description [src]

Copy a region from source buffer to destination buffer.

If the babl_formats of the buffers are the same, and the tile boundaries align, this will create copy-on-write tiles in the destination buffer.

This function never does any scaling. When src_rect and dst_rect do not have the same width and height, the size of src_rect is used.

Parameters

src_rect

Type: GeglRectangle

Source rectangle (or NULL to copy entire source buffer)

The data is owned by the caller of the function.

repeat_mode

Type: GeglAbyssPolicy

The abyss policy to be using if src_rect is outside src’s extent.

dst

Type: GeglBuffer

Destination buffer.

The data is owned by the caller of the function.

dst_rect

Type: GeglRectangle

Position of upper left destination pixel (or NULL to match src_rect)

The data is owned by the caller of the function.
