Vips Imagenew_from_buffer

Declaration [src]

Description [src]

Loads an image from the formatted area of memory buf, len using the loader recommended by vips_foreign_find_load_buffer(). To load an unformatted area of memory, usevips_image_new_from_memory().

VIPS does not take responsibility for the area of memory, it’s up to you to make sure it’s freed when the image is closed. See for example VipsObject::close.

Load options may be given in option_string as [name=value,...] or given as a NULL-terminated list of name-value pairs at the end of the arguments. Options given in the function call override options given in the filename.

This constructor is not directly available to language bindings.
