Constructor

VipsImagenew_from_buffer

Declaration [src] 

VipsImage*
vips_image_new_from_buffer (
  void* buf,
  size_t len,
  const char* option_string,
  ...
)

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, use vips_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.
