set_from_buffer_at_size

Description:

public bool set_from_buffer_at_size (owned uint8[] buffer, DestroyNotify? buffer_free_func, int width, int height) throws Error

Set the image data from unencoded image data, stored in memory, and scales it while loading.

In case of failure, false is returned and error is set. It is expected that buffer will remain accessible for the duration of the load. Once it is finished with, buffer_free_func will be called. The aspect ratio will always be maintained.

Parameters:

this	An Image
buffer	A buffer pointing to encoded image data
buffer_free_func	A function to free `buffer`, or `null`
width	Width to scale the image to, or -1
height	Height to scale the image to, or -1
buffer_size	The size of `buffer`, in bytes

Returns:

true if the image was successfully updated
