Method

VipsImageget_data

Declaration [src]

void*
vips_image_get_data (
  VipsImage* image
)

Description [src]

Return a pointer to the image’s pixel data, if possible. This can involve allocating large amounts of memory and performing a long computation. Image pixels are laid out in band-packed rows.

Since this function modifies image, it is not threadsafe. Only call it on images which you are sure have not been shared with another thread.

Return value

Returns:	`void*`
	A pointer to pixel data, if possible.
	The data is owned by the instance.
	The return value can be `NULL`.
