public uint8[] introspectable_get (Rectangle rect, double scale, string? format_name, AbyssPolicy repeat_mode)
Fetch a rectangular linear buffer of pixel data from the GeglBuffer.
| this |
the buffer to retrieve data from. |
| rect |
the coordinates we want to retrieve data from. |
| scale |
sampling scale, 1.0 = pixel for pixel 2.0 = magnify, 0.5 scale down. |
| format_name |
the format to store data in, if NULL the format of the buffer is used. |
| repeat_mode |
how 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 |
The length of the returned buffer |
|
A copy of the requested data |
