Pixbuf.with_unowned_data
Description:
public Pixbuf.with_unowned_data (uint8[] data, Colorspace colorspace, bool has_alpha, int bits_per_sample, int width, int height, int rowstride, PixbufDestroyNotify? destroy_fn = null)
Creates a new Pixbuf out of in-memory image data.
Currently only RGB images with 8 bits per sample are supported.
Since you are providing a pre-allocated pixel buffer, you must also specify a way to free that data. This is done with a function of type `GdkPixbufDestroyNotify`. When a pixbuf created with is finalized, your destroy notification function will be called, and it is its responsibility to free the pixel array.

Parameters:
| data |
Image data in 8-bit/sample packed format |
| colorspace |
Colorspace for the image data |
| has_alpha |
Whether the data has an opacity channel |
| bits_per_sample |
Number of bits per sample |
| width |
Width of the image in pixels, must be > 0 |
| height |
Height of the image in pixels, must be > 0 |
| rowstride |
Distance in bytes between row starts |
| destroy_fn |
Function used to free the data when the pixbuf's reference count drops to zero, or |
| destroy_fn_data |
Closure data to pass to the destroy notification function |
Returns:
|
A newly-created pixbuf |
