Constructor

VipsImagewebpload_buffer

Declaration [src]

int
vips_webpload_buffer (
  void* buf,
  size_t len,
  VipsImage** out,
  ...
)

Description [src]

Read a WebP-formatted memory block into a VIPS image. Exactly as vips_webpload(), but read from a memory buffer.

You must not free the buffer while out is active. The VipsObject::postclose signal on out is a good place to free.

::: tip “Optional arguments” * page: gint, page (frame) to read * n: gint, load this many pages * scale: gdouble, scale by this much on load

::: seealso vips_webpload()
