Types

OpenImageInput (object)

The OpenImageInput is used to read images in OpenImageIO. You also get access to the image’s specification as a OpenImageSpec. The main relevant method on the OpenImageInput is the `read_image` method. Please see the example below.

Please refer to the official OpenImageIO documentation for more details (https://sites.google.com/site/openimageio/documentation).

/*
** Example: OpenImageInput
*/

require OpenImageIO;
require FileIO;

operator entry() {
  FilePath path = FilePath('${FABRIC_SCENE_GRAPH_DIR}/Python/Apps/Resources/images/brick_d.png').expandEnvVars();

  OpenImageInput img(path.string());
  OpenImageSpec spec = img.spec();

  report(spec.get_full_width());
  report(spec.get_full_height());

  OpenImageTypeDesc desc = OpenImageTypeDesc(OpenImage_BASETYPE_UINT8, OpenImage_AGGREGATE_SCALAR, OpenImage_VECSEMANTICS_NOXFORM);

  Byte bytes[];
  bytes.resize(spec.get_full_width() * spec.get_full_height() * spec.get_nchannels());
  Data data = bytes.data();
  
  img.read_image(desc, data, 0, 0, 0);

  report(bytes[0]);
  report(bytes[1]);
  report(bytes[2]);
}
