* @filename: file to load

*
|

* Read a virtual slide supported by the OpenSlide library into a VIPS image.
|
||||
* OpenSlide supports images in Aperio, Hamamatsu VMS, Hamamatsu VMU, MIRAX,
|
||||
* and Trestle formats. It also supports generic tiled TIFF images, but
|
||||
* im_openslide2vips() does not.
|
||||
*
|
||||
* To facilitate zooming, virtual slide formats include multiple scaled-down
|
||||
* versions of the high-resolution image. These are typically called
|
||||
* "levels", though OpenSlide and im_openslide2vips() call them "layers".
|
||||
* By default, im_openslide2vips() reads the highest-resolution layer
|
||||
* (layer 0). To read a different layer, specify the layer number as part
|
||||
* of the filename (for example, "CMU-1.mrxs:3").
|
||||
*
|
||||
* In addition to the slide image itself, virtual slide formats sometimes
|
||||
* include additional images, such as a scan of the slide's barcode.
|
||||
* OpenSlide calls these "associated images". To read an associated image,
|
||||
* specify the image's name as part of the filename (for example,
|
||||
* "CMU-1.mrxs:label"). A slide's associated images are listed in the
|
||||
* "slide-associated-images" metadata item.
|
||||
*
|
||||
* See also: #VipsFormat
|
||||
*
|
||||
* Returns: 0 on success, -1 on error.
