)
Description [src]
Fetch a rectangular linear buffer of pixel data from the GeglBuffer.
This method is renamed to gegl_buffer_get() in language bindings
Parameters
rect-
Type:
GeglRectangleThe coordinates we want to retrieve data from.
The data is owned by the caller of the function. scale-
Type:
gdoubleSampling scale, 1.0 = pixel for pixel 2.0 = magnify, 0.5 scale down.
format_name-
Type:
const gchar*The format to store data in, if NULL the format of the buffer is used.
The argument can be NULL.The data is owned by the caller of the function. The value is a NUL terminated UTF-8 string. repeat_mode-
Type:
GeglAbyssPolicyHow requests outside the buffer extent are handled. Valid values: GEGL_ABYSS_NONE (abyss pixels are zeroed), GEGL_ABYSS_WHITE (abyss pixels are white), GEGL_ABYSS_BLACK (abyss pixels are black), GEGL_ABYSS_CLAMP (coordinates are clamped to the abyss rectangle), GEGL_ABYSS_LOOP (buffer contents are tiled if outside of the abyss rectangle).
data_length-
Type:
guint*The length of the returned buffer.
The argument will be set by the function.
